  13. INTRODUCTION TO ARCNET
  14. ----------------------
  15. ARCnet is a network type which works in a way similar to popular Ethernet
  16. networks but which is also different in some very important ways.
  17. First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
  18. (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
  19. there are others as well, but these are less common. The different hardware
  20. types, as far as I'm aware, are not compatible and so you cannot wire a
  21. 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
  22. work with 100 Mbps cards, but I haven't been able to verify this myself,
  23. since I only have the 2.5 Mbps variety. It is probably not going to saturate
  24. your 100 Mbps card. Stop complaining. :)
  25. You also cannot connect an ARCnet card to any kind of Ethernet card and
  26. expect it to work.
  27. There are two "types" of ARCnet - STAR topology and BUS topology. This
  28. refers to how the cards are meant to be wired together. According to most
  29. available documentation, you can only connect STAR cards to STAR cards and
  30. BUS cards to BUS cards. That makes sense, right? Well, it's not quite
  31. true; see below under "Cabling."
  32. Once you get past these little stumbling blocks, ARCnet is actually quite a
  33. well-designed standard. It uses something called "modified token passing"
  34. which makes it completely incompatible with so-called "Token Ring" cards,
  35. but which makes transfers much more reliable than Ethernet does. In fact,
  36. ARCnet will guarantee that a packet arrives safely at the destination, and
  37. even if it can't possibly be delivered properly (ie. because of a cable
  38. break, or because the destination computer does not exist) it will at least
  39. tell the sender about it.
  40. Because of the carefully defined action of the "token", it will always make
  41. a pass around the "ring" within a maximum length of time. This makes it
  42. useful for realtime networks.
  43. In addition, all known ARCnet cards have an (almost) identical programming
  44. interface. This means that with one ARCnet driver you can support any
  45. card, whereas with Ethernet each manufacturer uses what is sometimes a
  46. completely different programming interface, leading to a lot of different,
  47. sometimes very similar, Ethernet drivers. Of course, always using the same
  48. programming interface also means that when high-performance hardware
  49. facilities like PCI bus mastering DMA appear, it's hard to take advantage of
  50. them. Let's not go into that.
  51. One thing that makes ARCnet cards difficult to program for, however, is the
  52. limit on their packet sizes; standard ARCnet can only send packets that are
  53. up to 508 bytes in length. This is smaller than the Internet "bare minimum"
  54. of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
  55. level of encapsulation is defined by RFC1201, which I call "packet
  56. splitting," that allows "virtual packets" to grow as large as 64K each,
  57. although they are generally kept down to the Ethernet-style 1500 bytes.
  58. For more information on the advantages and disadvantages (mostly the
  59. advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

  64. This section was rewritten by
  65. Vojtech Pavlik <vojtech@suse.cz>
  66. using information from several people, including:
  67. Avery Pennraun <apenwarr@worldvisions.ca>
  68. Stephen A. Wood <saw@hallc1.cebaf.gov>
  69. John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
  70. Joachim Koenig <jojo@repas.de>
  71. and Avery touched it up a bit, at Vojtech's request.
  72. ARCnet (the classic 2.5 Mbps version) can be connected by two different
  73. types of cabling: coax and twisted pair. The other ARCnet-type networks
  74. (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
  75. cabling (Type1, Fiber, C1, C4, C5).
  76. For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
  77. also work fine, because ARCnet is a very stable network. I personally use 75
  78. Ohm TV antenna cable.
  79. Cards for coax cabling are shipped in two different variants: for BUS and
  80. STAR network topologies. They are mostly the same. The only difference
  81. lies in the hybrid chip installed. BUS cards use high impedance output,
  82. while STAR use low impedance. Low impedance card (STAR) is electrically
  83. equal to a high impedance one with a terminator installed.
  84. Usually, the ARCnet networks are built up from STAR cards and hubs. There
  85. are two types of hubs - active and passive. Passive hubs are small boxes
  86. with four BNC connectors containing four 47 Ohm resistors:
  87. | | wires
  88. R + junction
  89. -R-+-R- R 47 Ohm resistors
  90. R
  91. |
  92. The shielding is connected together. Active hubs are much more complicated;
  93. they are powered and contain electronics to amplify the signal and send it
  94. to other segments of the net. They usually have eight connectors. Active
  95. hubs come in two variants - dumb and smart. The dumb variant just
  96. amplifies, but the smart one decodes to digital and encodes back all packets
  97. coming through. This is much better if you have several hubs in the net,
  98. since many dumb active hubs may worsen the signal quality.
  99. And now to the cabling. What you can connect together:
  100. 1. A card to a card. This is the simplest way of creating a 2-computer
  101. network.
  102. 2. A card to a passive hub. Remember that all unused connectors on the hub
  103. must be properly terminated with 93 Ohm (or something else if you don't
  104. have the right ones) terminators.
  105. (Avery's note: oops, I didn't know that. Mine (TV cable) works
  106. anyway, though.)
  107. 3. A card to an active hub. Here is no need to terminate the unused
  108. connectors except some kind of aesthetic feeling. But, there may not be
  109. more than eleven active hubs between any two computers. That of course
  110. doesn't limit the number of active hubs on the network.
  111. 4. An active hub to another.
  112. 5. An active hub to passive hub.
  113. Remember that you cannot connect two passive hubs together. The power loss
  114. implied by such a connection is too high for the net to operate reliably.
  115. An example of a typical ARCnet network:
  116. R S - STAR type card
  117. S------H--------A-------S R - Terminator
  118. | | H - Hub
  119. | | A - Active hub
  120. | S----H----S
  121. S |
  122. |
  123. S
  124. The BUS topology is very similar to the one used by Ethernet. The only
  125. difference is in cable and terminators: they should be 93 Ohm. Ethernet
  126. uses 50 Ohm impedance. You use T connectors to put the computers on a single
  127. line of cable, the bus. You have to put terminators at both ends of the
  128. cable. A typical BUS ARCnet network looks like:
  129. RT----T------T------T------T------TR
  130. B B B B B B
  131. B - BUS type card
  132. R - Terminator
  133. T - T connector
  134. But that is not all! The two types can be connected together. According to
  135. the official documentation the only way of connecting them is using an active
  136. hub:
  137. A------T------T------TR
  138. | B B B
  139. S---H---S
  140. |
  141. S
  142. The official docs also state that you can use STAR cards at the ends of
  143. BUS network in place of a BUS card and a terminator:
  144. S------T------T------S
  145. B B
  146. But, according to my own experiments, you can simply hang a BUS type card
  147. anywhere in middle of a cable in a STAR topology network. And more - you
  148. can use the bus card in place of any star card if you use a terminator. Then
  149. you can build very complicated networks fulfilling all your needs! An
  150. example:
  151. S
  152. |
  153. RT------T-------T------H------S
  154. B B B |
  155. | R
  156. S------A------T-------T-------A-------H------TR
  157. | B B | | B
  158. | S BT |
  159. | | | S----A-----S
  160. S------H---A----S | |
  161. | | S------T----H---S |
  162. S S B R S
  163. A basically different cabling scheme is used with Twisted Pair cabling. Each
  164. of the TP cards has two RJ (phone-cord style) connectors. The cards are
  165. then daisy-chained together using a cable connecting every two neighboring
  166. cards. The ends are terminated with RJ 93 Ohm terminators which plug into
  167. the empty connectors of cards on the ends of the chain. An example:
  168. ___________ ___________
  169. _R_|_ _|_|_ _|_R_
  170. | | | | | |
  171. |Card | |Card | |Card |
  172. |_____| |_____| |_____|
  173. There are also hubs for the TP topology. There is nothing difficult
  174. involved in using them; you just connect a TP chain to a hub on any end or
  175. even at both. This way you can create almost any network configuration.
  176. The maximum of 11 hubs between any two computers on the net applies here as
  177. well. An example:
  178. RP-------P--------P--------H-----P------P-----PR
  179. |
  180. RP-----H--------P--------H-----P------PR
  181. | |
  182. PR PR
  183. R - RJ Terminator
  184. P - TP Card
  185. H - TP Hub
  186. Like any network, ARCnet has a limited cable length. These are the maximum
  187. cable lengths between two active ends (an active end being an active hub or
  188. a STAR card).
  189. RG-62 93 Ohm up to 650 m
  190. RG-59/U 75 Ohm up to 457 m
  191. RG-11/U 75 Ohm up to 533 m
  192. IBM Type 1 150 Ohm up to 200 m
  193. IBM Type 3 100 Ohm up to 100 m
  194. The maximum length of all cables connected to a passive hub is limited to 65
  195. meters for RG-62 cabling; less for others. You can see that using passive
  196. hubs in a large network is a bad idea. The maximum length of a single "BUS
  197. Trunk" is about 300 meters for RG-62. The maximum distance between the two
  198. most distant points of the net is limited to 3000 meters. The maximum length
  199. of a TP cable between two cards/hubs is 650 meters.
  200. SETTING THE JUMPERS
  201. -------------------
  202. All ARCnet cards should have a total of four or five different settings:
  203. - the I/O address: this is the "port" your ARCnet card is on. Probed
  204. values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
  205. your card has additional ones, which is possible, please tell me.) This
  206. should not be the same as any other device on your system. According to
  207. a doc I got from Novell, MS Windows prefers values of 0x300 or more,
  208. eating net connections on my system (at least) otherwise. My guess is
  209. this may be because, if your card is at 0x2E0, probing for a serial port
  210. at 0x2E8 will reset the card and probably mess things up royally.
  211. - Avery's favourite: 0x300.
  212. - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
  213. on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
  214. Make sure this is different from any other card on your system. Note
  215. that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
  216. "cat /proc/interrupts" for a somewhat complete list of which ones are in
  217. use at any given time. Here is a list of common usages from Vojtech
  218. Pavlik <vojtech@suse.cz>:
  219. ("Not on bus" means there is no way for a card to generate this
  220. interrupt)
  221. IRQ 0 - Timer 0 (Not on bus)
  222. IRQ 1 - Keyboard (Not on bus)
  223. IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
  224. IRQ 3 - COM2
  225. IRQ 4 - COM1
  226. IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
  227. IRQ 6 - Floppy disk controller
  228. IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP)
  229. IRQ 8 - Realtime Clock Interrupt (Not on bus)
  230. IRQ 9 - FREE (VGA vertical sync interrupt if enabled)
  231. IRQ 10 - FREE
  232. IRQ 11 - FREE
  233. IRQ 12 - FREE
  234. IRQ 13 - Numeric Coprocessor (Not on bus)
  235. IRQ 14 - Fixed Disk Controller
  236. IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
  237. Note: IRQ 9 is used on some video cards for the "vertical retrace"
  238. interrupt. This interrupt would have been handy for things like
  239. video games, as it occurs exactly once per screen refresh, but
  240. unfortunately IBM cancelled this feature starting with the original
  241. VGA and thus many VGA/SVGA cards do not support it. For this
  242. reason, no modern software uses this interrupt and it can almost
  243. always be safely disabled, if your video card supports it at all.
  244. If your card for some reason CANNOT disable this IRQ (usually there
  245. is a jumper), one solution would be to clip the printed circuit
  246. contact on the board: it's the fourth contact from the left on the
  247. back side. I take no responsibility if you try this.
  248. - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
  249. - the memory address: Unlike most cards, ARCnets use "shared memory" for
  250. copying buffers around. Make SURE it doesn't conflict with any other
  251. used memory in your system!
  252. A0000 - VGA graphics memory (ok if you don't have VGA)
  253. B0000 - Monochrome text mode
  254. C0000 \ One of these is your VGA BIOS - usually C0000.
  255. E0000 /
  256. F0000 - System BIOS
  257. Anything less than 0xA0000 is, well, a BAD idea since it isn't above
  258. 640k.
  259. - Avery's favourite: 0xD0000
  260. - the station address: Every ARCnet card has its own "unique" network
  261. address from 0 to 255. Unlike Ethernet, you can set this address
  262. yourself with a jumper or switch (or on some cards, with special
  263. software). Since it's only 8 bits, you can only have 254 ARCnet cards
  264. on a network. DON'T use 0 or 255, since these are reserved (although
  265. neat stuff will probably happen if you DO use them). By the way, if you
  266. haven't already guessed, don't set this the same as any other ARCnet on
  267. your network!
  268. - Avery's favourite: 3 and 4. Not that it matters.
  269. - There may be ETS1 and ETS2 settings. These may or may not make a
  270. difference on your card (many manuals call them "reserved"), but are
  271. used to change the delays used when powering up a computer on the
  272. network. This is only necessary when wiring VERY long range ARCnet
  273. networks, on the order of 4km or so; in any case, the only real
  274. requirement here is that all cards on the network with ETS1 and ETS2
  275. jumpers have them in the same position. Chris Hindy <chrish@io.org>
  276. sent in a chart with actual values for this:
  277. ET1 ET2 Response Time Reconfiguration Time
  278. --- --- ------------- --------------------
  279. open open 74.7us 840us
  280. open closed 283.4us 1680us
  281. closed open 561.8us 1680us
  282. closed closed 1118.6us 1680us
  283. Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
  284. network.
  285. Also, on many cards (not mine, though) there are red and green LED's.
  286. Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:
  287. GREEN RED Status
  288. ----- --- ------
  289. OFF OFF Power off
  290. OFF Short flashes Cabling problems (broken cable or not
  291. terminated)
  292. OFF (short) ON Card init
  293. ON ON Normal state - everything OK, nothing
  294. happens
  295. ON Long flashes Data transfer
  296. ON OFF Never happens (maybe when wrong ID)
  297. The following is all the specific information people have sent me about
  298. their own particular ARCnet cards. It is officially a mess, and contains
  299. huge amounts of duplicated information. I have no time to fix it. If you
  300. want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
  301. The model # is listed right above specifics for that card, so you should be
  302. able to use your text viewer's "search" function to find the entry you want.
  303. If you don't KNOW what kind of card you have, try looking through the
  304. various diagrams to see if you can tell.
  305. If your model isn't listed and/or has different settings, PLEASE PLEASE
  306. tell me. I had to figure mine out without the manual, and it WASN'T FUN!
  307. Even if your ARCnet model isn't listed, but has the same jumpers as another
  308. model that is, please e-mail me to say so.

  512. Setting the Base Memory (RAM) buffer Address
  513. --------------------------------------------
  514. The memory buffer requires 2K of a 16K block of RAM. The base of this
  515. 16K block can be located in any of eight positions.
  516. Switches 4-6 of switch group S1 select the Base of the 16K block.
  517. Within that 16K address space, the buffer may be assigned any one of four
  518. positions, determined by the offset, switches 7 and 8 of group S1.

  561. *) To enable the 8K Boot PROM install the jumper ROM.
  562. The default is jumper ROM not installed.
  563. Setting the Timeouts and Interrupt
  564. ----------------------------------
  565. The jumpers labeled EXT1 and EXT2 are used to determine the timeout
  566. parameters. These two jumpers are normally left open.
  567. To select a hardware interrupt level set one (only one!) of the jumpers
  568. IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
  569. Configuring the PC130E for Star or Bus Topology
  570. -----------------------------------------------
  571. The single jumper labeled STAR is used to configure the PC130E board for
  572. star or bus topology.
  573. When the jumper is installed, the board may be used in a star network, when
  574. it is removed, the board can be used in a bus topology.
  575. Diagnostic LEDs
  576. ---------------
  577. Two diagnostic LEDs are visible on the rear bracket of the board.
  578. The green LED monitors the network activity: the red one shows the
  579. board activity:
  580. Green | Status Red | Status
  581. -------|------------------- ---------|-------------------
  582. on | normal activity flash/on | data transfer
  583. blink | reconfiguration off | no data transfer;

  591. STANDARD MICROSYSTEMS CORPORATION (SMC) ARCNET-PC500/PC550 Long Board
  592. =====================================================================
  593. Note: There is another Version of the PC500 called Short Version, which
  594. is different in hard- and software! The most important differences
  595. are:
  596. - The long board has no Shared memory.
  597. - On the long board the selection of the interrupt is done by binary
  598. coded switch, on the short board directly by jumper.
  599. [Avery's note: pay special attention to that: the long board HAS NO SHARED
  600. MEMORY. This means the current Linux-ARCnet driver can't use these cards.
  601. I have obtained a PC500Longboard and will be doing some experiments on it in
  602. the future, but don't hold your breath. Thanks again to Juergen Seifert for
  603. his advice about this!]

  659. Setting one of the switches to Off/Open means "1", On/Closed means "0".
  660. Setting the Node ID
  661. -------------------
  662. The eight switches in group SW3 are used to set the node ID. Each node
  663. attached to the network must have an unique node ID which must be
  664. different from 0.
  665. Switch 1 serves as the least significant bit (LSB).
  666. The node ID is the sum of the values of all switches set to "1"
  667. These values are:
  668. Switch | Value
  669. -------|-------
  670. 1 | 1
  671. 2 | 2
  672. 3 | 4
  673. 4 | 8
  674. 5 | 16
  675. 6 | 32
  676. 7 | 64
  677. 8 | 128
  678. Some Examples:
  679. Switch | Hex | Decimal
  680. 8 7 6 5 4 3 2 1 | Node ID | Node ID

  693. 1 1 1 1 1 1 1 1 | FF | 255
  694. Setting the I/O Base Address
  695. ----------------------------
  696. The first six switches in switch group SW1 are used to select one
  697. of 32 possible I/O Base addresses using the following table
  698. Switch | Hex I/O
  699. 6 5 4 3 2 1 | Address
  700. -------------|--------

  732. 1 1 1 1 1 1 | 3F0
  733. Setting the Interrupt
  734. ---------------------
  735. Switches seven through ten of switch group SW1 are used to select the
  736. interrupt level. The interrupt level is binary coded, so selections
  737. from 0 to 15 would be possible, but only the following eight values will
  738. be supported: 3, 4, 5, 7, 9, 10, 11, 12.
  739. Switch | IRQ
  740. 10 9 8 7 |
  741. ---------|--------
  742. 0 0 1 1 | 3
  743. 0 1 0 0 | 4
  744. 0 1 0 1 | 5
  745. 0 1 1 1 | 7
  746. 1 0 0 1 | 9 (=2) (default)
  747. 1 0 1 0 | 10
  748. 1 0 1 1 | 11
  749. 1 1 0 0 | 12
  750. Setting the Timeouts
  751. --------------------
  752. The two jumpers JP2 (1-4) are used to determine the timeout parameters.
  753. These two jumpers are normally left open.
  754. Refer to the COM9026 Data Sheet for alternate configurations.
  755. Configuring the PC500 for Star or Bus Topology
  756. ----------------------------------------------
  757. The single jumper labeled JP6 is used to configure the PC500 board for
  758. star or bus topology.
  759. When the jumper is installed, the board may be used in a star network, when
  760. it is removed, the board can be used in a bus topology.
  761. Diagnostic LEDs
  762. ---------------
  763. Two diagnostic LEDs are visible on the rear bracket of the board.
  764. The green LED monitors the network activity: the red one shows the
  765. board activity:
  766. Green | Status Red | Status
  767. -------|------------------- ---------|-------------------
  768. on | normal activity flash/on | data transfer
  769. blink | reconfiguration off | no data transfer;
  770. off | defective board or | incorrect memory or
  771. | node ID is zero | I/O address

  775. ------------------
  776. - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
  777. Note: this data is gathered by experimenting and looking at info of other
  778. cards. However, I'm sure I got 99% of the settings right.
  779. The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
  780. LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:

  799. The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
  800. labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
  801. IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
  802. S1 and S2 perform the same function as on the PC270, only their numbers
  803. are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
  804. I know it works when connected to a PC110 type ARCnet board.

  808. ---------------------------------
  809. - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
  810. - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
  811. LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
  812. only (the JP0 jumper is hardwired), and BNC only.
  813. This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
  814. nowhere else, not even on the few Xeroxed sheets from the manual).

  901. - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
  902. are mostly the same as this. PDI508Plus cards appear to be mainly
  903. software-configured.
  904. Jumpers:
  905. There is a jumper array at the bottom of the card, near the edge
  906. connector. This array is labelled J1. They control the IRQs and
  907. something else. Put only one jumper on the IRQ pins.
  908. ETS1, ETS2 are for timing on very long distance networks. See the
  909. more general information near the top of this file.
  910. There is a J2 jumper on two pins. A jumper should be put on them,
  911. since it was already there when I got the card. I don't know what
  912. this jumper is for though.
  913. There is a two-jumper array for J3. I don't know what it is for,
  914. but there were already two jumpers on it when I got the card. It's
  915. a six pin grid in a two-by-three fashion. The jumpers were
  916. configured as follows:
  917. .-------.
  918. o | o o |
  919. :-------: ------> Accessible end of card with connectors
  920. o | o o | in this direction ------->
  921. `-------'
  922. Carl de Billy <CARL@carainfo.com> explains J3 and J4:

  934. - If using coax cable in a bus topology the J4 jumper must be removed;
  935. place it on one pin.
  936. - If using bus topology with twisted pair wiring move the J3
  937. jumpers so they connect the middle pin and the pins closest to the RJ11
  938. Connectors. Also the J4 jumper must be removed; place it on one pin of
  939. J4 jumper for storage.
  940. - If using star topology with twisted pair wiring move the J3
  941. jumpers so they connect the middle pin and the pins closest to the RJ11
  942. connectors.
  943. DIP Switches:
  944. The DIP switches accessible on the accessible end of the card while
  945. it is installed, is used to set the ARCnet address. There are 8
  946. switches. Use an address from 1 to 254.
  947. Switch No.
  948. 12345678 ARCnet address
  949. -----------------------------------------
  950. 00000000 FF (Don't use this!)
  951. 00000001 FE
  952. 00000010 FD
  953. ....
  954. 11111101 2
  955. 11111110 1
  956. 11111111 0 (Don't use this!)
  957. There is another array of eight DIP switches at the top of the
  958. card. There are five labelled MS0-MS4 which seem to control the
  959. memory address, and another three labelled IO0-IO2 which seem to
  960. control the base I/O address of the card.
  961. This was difficult to test by trial and error, and the I/O addresses
  962. are in a weird order. This was tested by setting the DIP switches,
  963. rebooting the computer, and attempting to load ARCETHER at various
  964. addresses (mostly between 0x200 and 0x400). The address that caused
  965. the red transmit LED to blink, is the one that I thought works.
  966. Also, the address 0x3D0 seem to have a special meaning, since the
  967. ARCETHER packet driver loaded fine, but without the red LED
  968. blinking. I don't know what 0x3D0 is for though. I recommend using
  969. an address of 0x300 since Windows may not like addresses below
  970. 0x300.
  971. IO Switch No.
  972. 210 I/O address
  973. -------------------------------
  974. 111 0x260
  975. 110 0x290
  976. 101 0x2E0
  977. 100 0x2F0
  978. 011 0x300
  979. 010 0x350
  980. 001 0x380
  981. 000 0x3E0
  982. The memory switches set a reserved address space of 0x1000 bytes
  983. (0x100 segment units, or 4k). For example if I set an address of
  984. 0xD000, it will use up addresses 0xD000 to 0xD100.
  985. The memory switches were tested by booting using QEMM386 stealth,
  986. and using LOADHI to see what address automatically became excluded
  987. from the upper memory regions, and then attempting to load ARCETHER
  988. using these addresses.
  989. I recommend using an ARCnet memory address of 0xD000, and putting
  990. the EMS page frame at 0xC000 while using QEMM stealth mode. That
  991. way, you get contiguous high memory from 0xD100 almost all the way
  992. the end of the megabyte.
  993. Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
  994. on my card. It could be malfunctioning on my card. Experiment with
  995. it ON first, and if it doesn't work, set it to OFF. (It may be a
  996. modifier for the 0x200 bit?)
  997. MS Switch No.
  998. 43210 Memory address
  999. --------------------------------
  1000. 00001 0xE100 (guessed - was not detected by QEMM)
  1001. 00011 0xE000 (guessed - was not detected by QEMM)
  1002. 00101 0xDD00
  1003. 00111 0xDC00
  1004. 01001 0xD900
  1005. 01011 0xD800
  1006. 01101 0xD500
  1007. 01111 0xD400
  1008. 10001 0xD100
  1009. 10011 0xD000
  1010. 10101 0xCD00
  1011. 10111 0xCC00
  1012. 11001 0xC900 (guessed - crashes tested system)
  1013. 11011 0xC800 (guessed - crashes tested system)
  1014. 11101 0xC500 (guessed - crashes tested system)

  1082. Setting the Node ID
  1083. -------------------
  1084. The eight switches in SW2 are used to set the node ID. Each node attached
  1085. to the network must have an unique node ID which must be different from 0.
  1086. Switch 1 (ID0) serves as the least significant bit (LSB).
  1087. The node ID is the sum of the values of all switches set to "1"
  1088. These values are:
  1089. Switch | Label | Value
  1090. -------|-------|-------
  1091. 1 | ID0 | 1
  1092. 2 | ID1 | 2
  1093. 3 | ID2 | 4
  1094. 4 | ID3 | 8

  1114. 1 1 1 1 1 1 1 1 | FF | 255
  1115. Setting the I/O Base Address
  1116. ----------------------------
  1117. The last three switches in switch block SW1 are used to select one
  1118. of eight possible I/O Base addresses using the following table
  1119. Switch | Hex I/O
  1120. 6 7 8 | Address
  1121. ------------|--------
  1122. ON ON ON | 260
  1123. OFF ON ON | 290
  1124. ON OFF ON | 2E0 (Manufacturer's default)
  1125. OFF OFF ON | 2F0
  1126. ON ON OFF | 300
  1127. OFF ON OFF | 350
  1128. ON OFF OFF | 380
  1129. OFF OFF OFF | 3E0
  1130. Setting the Base Memory (RAM) buffer Address
  1131. --------------------------------------------
  1132. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1133. located in any of eight positions. The address of the Boot Prom is
  1134. memory base + 8K or memory base + 0x2000.
  1135. Switches 1-5 of switch block SW1 select the Memory Base address.
  1136. Switch | Hex RAM | Hex ROM
  1137. 1 2 3 4 5 | Address | Address *)
  1138. --------------------|---------|-----------
  1139. ON ON ON ON ON | C0000 | C2000
  1140. ON ON OFF ON ON | C4000 | C6000
  1141. ON ON ON OFF ON | CC000 | CE000
  1142. ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
  1143. ON ON ON ON OFF | D4000 | D6000
  1144. ON ON OFF ON OFF | D8000 | DA000
  1145. ON ON ON OFF OFF | DC000 | DE000
  1146. ON ON OFF OFF OFF | E0000 | E2000
  1147. *) To enable the Boot ROM install the jumper JP1
  1148. Note: Since the switches 1 and 2 are always set to ON it may be possible
  1149. that they can be used to add an offset of 2K, 4K or 6K to the base
  1150. address, but this feature is not documented in the manual and I
  1151. haven't tested it yet.
  1152. Setting the Interrupt Line
  1153. --------------------------
  1154. To select a hardware interrupt level install one (only one!) of the jumpers
  1155. JP2, JP3, JP4, JP5, JP6. JP2 is the default.
  1156. Jumper | IRQ
  1157. -------|-----

  1187. Setting the Timeout Parameters
  1188. ------------------------------
  1189. The jumpers labeled EXT1 and EXT2 are used to determine the timeout
  1190. parameters. These two jumpers are normally left open.

  1280. Setting the I/O Base Address
  1281. ----------------------------
  1282. The first six switches in switch block SW1 are used to select the I/O Base
  1283. address using the following table:
  1284. Switch | Hex I/O
  1285. 1 2 3 4 5 6 | Address
  1286. ------------------------|--------
  1287. OFF ON ON OFF OFF ON | 260
  1288. OFF ON OFF ON ON OFF | 290
  1289. OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)

  1291. OFF OFF ON ON ON ON | 300
  1292. OFF OFF ON OFF ON OFF | 350
  1293. OFF OFF OFF ON ON ON | 380
  1294. OFF OFF OFF OFF OFF ON | 3E0
  1295. Note: Other IO-Base addresses seem to be selectable, but only the above
  1296. combinations are documented.
  1297. Setting the Base Memory (RAM) buffer Address
  1298. --------------------------------------------
  1299. The switches 7-10 of switch block SW1 are used to select the Memory
  1300. Base address of the RAM (2K) and the PROM.
  1301. Switch | Hex RAM | Hex ROM
  1302. 7 8 9 10 | Address | Address
  1303. ----------------|---------|-----------
  1304. OFF OFF ON ON | C0000 | C8000
  1305. OFF OFF ON OFF | D0000 | D8000 (Default)
  1306. OFF OFF OFF ON | E0000 | E8000
  1307. Note: Other MEM-Base addresses seem to be selectable, but only the above
  1308. combinations are documented.
  1309. Setting the Interrupt Line
  1310. --------------------------
  1311. To select a hardware interrupt level install one (only one!) of the jumpers
  1312. JP3 through JP13 using the following table:
  1313. Jumper | IRQ
  1314. -------|-----------------
  1315. 3 | 14
  1316. 4 | 15
  1317. 5 | 12
  1318. 6 | 11
  1319. 7 | 10
  1320. 8 | 3
  1321. 9 | 4
  1322. 10 | 5
  1323. 11 | 6
  1324. 12 | 7
  1325. 13 | 2 (=9) Default!
  1326. Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
  1327. Controller
  1328. - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
  1329. Hard Disk, it may conflict with their controllers
  1330. Setting the Timeout Parameters
  1331. ------------------------------
  1332. The jumpers labeled JP1 and JP2 are used to determine the timeout
  1333. parameters. These two jumpers are normally left open.

  1377. observe that some of those addresses are unusual and I didn't probe them; I
  1378. used a memory dump in DOS to identify them. For the 00000 configuration and
  1379. some others that I didn't write here the card seems to conflict with the

  1464. Setting the Node ID
  1465. -------------------
  1466. The eight switches in SW2 are used to set the node ID. Each node attached
  1467. to the network must have an unique node ID which must not be 0.
  1468. Switch 1 (ID0) serves as the least significant bit (LSB).
  1469. Setting one of the switches to OFF means "1", ON means "0".
  1470. The node ID is the sum of the values of all switches set to "1"
  1471. These values are:
  1472. Switch | Value
  1473. -------|-------
  1474. 1 | 1
  1475. 2 | 2
  1476. 3 | 4
  1477. 4 | 8
  1478. 5 | 16
  1479. 6 | 32
  1480. 7 | 64
  1481. 8 | 128
  1482. Don't set this to 0 or 255; these values are reserved.
  1483. Setting the I/O Base Address
  1484. ----------------------------
  1485. The switches 1 to 6 of switch block SW1 are used to select one
  1486. of 32 possible I/O Base addresses using the following tables
  1487. | Hex
  1488. Switch | Value
  1489. -------|-------
  1490. 1 | 200
  1491. 2 | 100
  1492. 3 | 80
  1493. 4 | 40
  1494. 5 | 20
  1495. 6 | 10
  1496. The I/O address is sum of all switches set to "1". Remember that
  1497. the I/O address space bellow 0x200 is RESERVED for mainboard, so
  1498. switch 1 should be ALWAYS SET TO OFF.
  1499. Setting the Base Memory (RAM) buffer Address
  1500. --------------------------------------------
  1501. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1502. located in any of sixteen positions. However, the addresses below
  1503. A0000 are likely to cause system hang because there's main RAM.
  1504. Jumpers 7-10 of switch block SW1 select the Memory Base address.
  1505. Switch | Hex RAM
  1506. 7 8 9 10 | Address
  1507. ----------------|---------
  1508. OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
  1509. OFF OFF OFF ON | E0000
  1510. OFF OFF ON OFF | D0000
  1511. OFF OFF ON ON | C0000 (conflicts with video BIOS)
  1512. OFF ON OFF OFF | B0000 (conflicts with mono video)
  1513. OFF ON OFF ON | A0000 (conflicts with graphics)
  1514. Setting the Interrupt Line
  1515. --------------------------
  1516. Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
  1517. shorted, OFF means open.
  1518. Jumper | IRQ
  1519. 1 2 3 4 5 |
  1520. ----------------------------
  1521. ON OFF OFF OFF OFF | 7
  1522. OFF ON OFF OFF OFF | 5
  1523. OFF OFF ON OFF OFF | 4
  1524. OFF OFF OFF ON OFF | 3
  1525. OFF OFF OFF OFF ON | 2
  1526. Unknown jumpers & sockets
  1527. -------------------------
  1528. I know nothing about these. I just guess that J16&J17 are timeout
  1529. jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
  1530. J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
  1531. guess the purpose.

  1607. Setting the Base Memory (RAM) buffer Address
  1608. --------------------------------------------
  1609. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1610. located in any of eight positions. The address of the Boot Prom is
  1611. memory base + 0x2000.
  1612. Jumpers 3-5 of switch block SW1 select the Memory Base address.

  1806. There is a DIP-switch with 8 switches, used to set the shared memory address
  1807. to be used. The first 6 switches set the address, the 7th doesn't have any
  1808. function, and the 8th switch is used to select "compatible" or "enhanced".
  1809. When I got my two cards, one of them had this switch set to "enhanced". That
  1810. card didn't work at all, it wasn't even recognized by the driver. The other
  1811. card had this switch set to "compatible" and it behaved absolutely normally. I
  1812. guess that the switch on one of the cards, must have been changed accidentally
  1813. when the card was taken out of its former host. The question remains
  1814. unanswered, what is the purpose of the "enhanced" position?
  1815. [Avery's note: "enhanced" probably either disables shared memory (use IO
  1816. ports instead) or disables IO ports (use memory addresses instead). This
  1817. varies by the type of card involved. I fail to see how either of these
  1818. enhance anything. Send me more detailed information about this mode, or
  1819. just use "compatible" mode instead.]

  1824. - from Robert Michael Best <rmb117@cs.usask.ca>
  1825. [Avery's note: these don't work with my driver for some reason. These cards
  1826. SEEM to have settings similar to the PDI508Plus, which is
  1827. software-configured and doesn't work with my driver either. The "Waterloo
  1828. chip" is a boot PROM, probably designed specifically for the University of
  1829. Waterloo. If you have any further information about this card, please
  1830. e-mail me.]
  1831. The probe has not been able to detect the card on any of the J2 settings,
  1832. and I tried them again with the "Waterloo" chip removed.

  1953. Setting the Node ID
  1954. -------------------
  1955. The eight switches in group SW1 are used to set the node ID.
  1956. Each node attached to the network must have an unique node ID which
  1957. must be different from 0.
  1958. Switch 8 serves as the least significant bit (LSB).
  1959. The node ID is the sum of the values of all switches set to "1"
  1960. These values are:
  1961. Switch | Value
  1962. -------|-------
  1963. 8 | 1
  1964. 7 | 2
  1965. 6 | 4
  1966. 5 | 8
  1967. 4 | 16
  1968. 3 | 32
  1969. 2 | 64
  1970. 1 | 128
  1971. Some Examples:
  1972. Switch | Hex | Decimal
  1973. 1 2 3 4 5 6 7 8 | Node ID | Node ID
  1974. ----------------|---------|---------

  1986. 1 1 1 1 1 1 1 1 | FF | 255
  1987. Setting the I/O Base Address
  1988. ----------------------------
  1989. The first three switches in switch group SW2 are used to select one
  1990. of eight possible I/O Base addresses using the following table
  1991. Switch | Hex I/O
  1992. 1 2 3 | Address
  1993. ------------|--------
  1994. ON ON ON | 260
  1995. ON ON OFF | 290
  1996. ON OFF ON | 2E0 (Manufacturer's default)
  1997. ON OFF OFF | 2F0
  1998. OFF ON ON | 300
  1999. OFF ON OFF | 350
  2000. OFF OFF ON | 380
  2001. OFF OFF OFF | 3E0
  2002. Setting the Base Memory (RAM) buffer Address
  2003. --------------------------------------------
  2004. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2005. 16K block can be located in any of eight positions.
  2006. Switches 4-6 of switch group SW2 select the Base of the 16K block.
  2007. Within that 16K address space, the buffer may be assigned any one of four
  2008. positions, determined by the offset, switches 7 and 8 of group SW2.
  2009. Switch | Hex RAM | Hex ROM

  2051. *) To enable the 8K Boot PROM install the jumper ROM.
  2052. The default is jumper ROM not installed.
  2053. Setting Interrupt Request Lines (IRQ)
  2054. -------------------------------------
  2055. To select a hardware interrupt level set one (only one!) of the jumpers
  2056. IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
  2057. Setting the Timeouts
  2058. --------------------
  2059. The two jumpers labeled ET1 and ET2 are used to determine the timeout
  2060. parameters (response and reconfiguration time). Every node in a network
  2061. must be set to the same timeout values.
  2062. ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
  2063. --------|--------------------|--------------------------
  2064. Off Off | 78 | 840 (Default)

  2066. On Off | 563 | 1680
  2067. On On | 1130 | 1680
  2068. On means jumper installed, Off means jumper not installed
  2069. NONAME 16-BIT ARCNET
  2070. ====================
  2071. The manual of my 8-Bit NONAME ARCnet Card contains another description
  2072. of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
  2073. because there are missing two pages in the manual booklet. (The table
  2074. of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
  2075. the booklet there is a different way of counting ... 2-9, 2-10, A-1,
  2076. (empty page), 3-1, ..., 3-18, A-1 (again), A-2)
  2077. Also the picture of the board layout is not as good as the picture of
  2078. 8-Bit card, because there isn't any letter like "SW1" written to the
  2079. picture.
  2080. Should somebody have such a board, please feel free to complete this
  2081. description or to send a mail to me!

  2159. Setting the Base Memory (RAM) buffer Address
  2160. --------------------------------------------
  2161. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2162. 16K block can be located in any of eight positions.
  2163. Switches 6-8 of switch group SW1 select the Base of the 16K block.
  2164. Within that 16K address space, the buffer may be assigned any one of four
  2165. positions, determined by the offset, switches 4 and 5 of group SW1.

  2217. -----------
  2218. - from Vojtech Pavlik <vojtech@suse.cz>
  2219. I have named this ARCnet card "NONAME", since I got only the card with
  2220. no manual at all and the only text identifying the manufacturer is
  2221. "MADE IN TAIWAN R.O.C" printed on the card.

  2247. 90C65 ARCNET Chip
  2248. SW1 1-5: Base Memory Address Select
  2249. 6-8: Base I/O Address Select
  2250. SW2 1-8: Node ID Select (ID0-ID7)
  2251. SW3 1-5: IRQ Select
  2252. 6-7: Extra Timeout
  2253. 8 : ROM Enable
  2254. JP1 Led connector
  2255. BNC Coax connector
  2256. Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
  2257. switches.
  2258. Setting the jumpers to ON means connecting the upper two pins, off the bottom
  2259. two - or - in case of IRQ setting, connecting none of them at all.
  2260. Setting the Node ID
  2261. -------------------
  2262. The eight switches in SW2 are used to set the node ID. Each node attached
  2263. to the network must have an unique node ID which must not be 0.
  2264. Switch 1 (ID0) serves as the least significant bit (LSB).
  2265. Setting one of the switches to Off means "1", On means "0".
  2266. The node ID is the sum of the values of all switches set to "1"
  2267. These values are:
  2268. Switch | Label | Value
  2269. -------|-------|-------
  2270. 1 | ID0 | 1
  2271. 2 | ID1 | 2
  2272. 3 | ID2 | 4
  2273. 4 | ID3 | 8
  2274. 5 | ID4 | 16
  2275. 6 | ID5 | 32
  2276. 7 | ID6 | 64
  2277. 8 | ID7 | 128
  2278. Some Examples:
  2279. Switch | Hex | Decimal
  2280. 8 7 6 5 4 3 2 1 | Node ID | Node ID

  2293. 1 1 1 1 1 1 1 1 | FF | 255
  2294. Setting the I/O Base Address
  2295. ----------------------------
  2296. The last three switches in switch block SW1 are used to select one
  2297. of eight possible I/O Base addresses using the following table
  2298. Switch | Hex I/O
  2299. 6 7 8 | Address
  2300. ------------|--------
  2301. ON ON ON | 260
  2302. OFF ON ON | 290
  2303. ON OFF ON | 2E0 (Manufacturer's default)
  2304. OFF OFF ON | 2F0
  2305. ON ON OFF | 300
  2306. OFF ON OFF | 350
  2307. ON OFF OFF | 380
  2308. OFF OFF OFF | 3E0
  2309. Setting the Base Memory (RAM) buffer Address
  2310. --------------------------------------------
  2311. The memory buffer (RAM) requires 2K. The base of this buffer can be
  2312. located in any of eight positions. The address of the Boot Prom is
  2313. memory base + 0x2000.
  2314. Jumpers 3-5 of jumper block SW1 select the Memory Base address.
  2315. Switch | Hex RAM | Hex ROM
  2316. 1 2 3 4 5 | Address | Address *)
  2317. --------------------|---------|-----------
  2318. ON ON ON ON ON | C0000 | C2000
  2319. ON ON OFF ON ON | C4000 | C6000
  2320. ON ON ON OFF ON | CC000 | CE000
  2321. ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
  2322. ON ON ON ON OFF | D4000 | D6000
  2323. ON ON OFF ON OFF | D8000 | DA000
  2324. ON ON ON OFF OFF | DC000 | DE000
  2325. ON ON OFF OFF OFF | E0000 | E2000
  2326. *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
  2327. The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
  2328. Setting the Interrupt Line
  2329. --------------------------
  2330. Jumpers 1-5 of the jumper block SW3 control the IRQ level.
  2331. Jumper | IRQ
  2332. 1 2 3 4 5 |
  2333. ----------------------------
  2334. ON OFF OFF OFF OFF | 2
  2335. OFF ON OFF OFF OFF | 3
  2336. OFF OFF ON OFF OFF | 4
  2337. OFF OFF OFF ON OFF | 5
  2338. OFF OFF OFF OFF ON | 7
  2339. Setting the Timeout Parameters
  2340. ------------------------------
  2341. The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
  2342. parameters. These two jumpers are normally left in the OFF position.

  2392. SW1: Timeouts, Interrupt and ROM
  2393. ---------------------------------
  2394. To select a hardware interrupt level set one (only one!) of the dip switches
  2395. up (on) SW1...(switches 1-5)
  2396. IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
  2397. The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
  2398. are used to determine the timeout parameters. These two dip switches
  2399. are normally left off (down).
  2400. To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
  2401. The default is jumper ROM not installed.
  2402. Setting the I/O Base Address
  2403. ----------------------------
  2404. The last three switches in switch group SW2 are used to select one
  2405. of eight possible I/O Base addresses using the following table
  2406. Switch | Hex I/O
  2407. 4 5 6 | Address
  2408. -------|--------
  2409. 0 0 0 | 260

  2416. 1 1 1 | 3E0
  2417. Setting the Base Memory Address (RAM & ROM)
  2418. -------------------------------------------
  2419. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2420. 16K block can be located in any of eight positions.
  2421. Switches 1-3 of switch group SW2 select the Base of the 16K block.
  2422. (0 = DOWN, 1 = UP)
  2423. I could, however, only verify two settings...
  2424. Switch| Hex RAM | Hex ROM

  2434. 1 1 1 | ????? | ?????
  2435. Setting the Node ID
  2436. -------------------
  2437. The eight switches in group SW3 are used to set the node ID.
  2438. Each node attached to the network must have an unique node ID which
  2439. must be different from 0.
  2440. Switch 1 serves as the least significant bit (LSB).
  2441. switches in the DOWN position are OFF (0) and in the UP position are ON (1)
  2442. The node ID is the sum of the values of all switches set to "1"
  2443. These values are:
  2444. Switch | Value
  2445. -------|-------
  2446. 1 | 1
