  11. The Extended Industry Standard Architecture (EISA) bus was
  12. developed as an open alternative to the IBM MicroChannel bus.
  13. The EISA bus provided some of the features of the IBM MicroChannel
  14. bus while maintaining backward compatibility with cards made for
  15. the older ISA bus. The EISA bus saw limited use between 1988 and
  16. 1995 when it was made obsolete by the PCI bus.
  17. Say Y here if you are building a kernel for an EISA-based machine.
  18. Otherwise, say N.

  24. Activate this option if your system contains a Vesa Local
  25. Bus (VLB) card that identify itself as an EISA card (such as
  26. the Adaptec AHA-284x).
  27. When in doubt, say N.

  32. help
  33. Activate this option if your system contains a PCI to EISA
  34. bridge. If your system have both PCI and EISA slots, you
  35. certainly need this option.
  36. When in doubt, say Y.

  44. Activate this option if your system only have EISA bus
  45. (no PCI slots). The Alpha Jensen is an example of such
  46. a system.
  47. When in doubt, say Y.

  52. help
  53. By default, the kernel contains a database of all known EISA
  54. device names to make the information in sysfs comprehensible
  55. to the user. This database increases size of the kernel
  56. image by about 40KB, but it gets freed after the system
  57. boots up, so it doesn't take up kernel memory. Anyway, if
  58. you are building an installation floppy or kernel for an
  59. embedded system where kernel image size really matters, you
  60. can disable this feature and you'll get device ID instead of
  61. names.
  62. When in doubt, say Y.
