13	  The Extended Industry Standard Architecture (EISA) bus was
14	  developed as an open alternative to the IBM MicroChannel bus.
15
16	  The EISA bus provided some of the features of the IBM MicroChannel
17	  bus while maintaining backward compatibility with cards made for
18	  the older ISA bus.  The EISA bus saw limited use between 1988 and
19	  1995 when it was made obsolete by the PCI bus.
20
21	  Say Y here if you are building a kernel for an EISA-based machine.
22
23	  Otherwise, say N.

29	help
30	  Activate this option if your system contains a Vesa Local
31	  Bus (VLB) card that identify itself as an EISA card (such as
32	  the Adaptec AHA-284x).
33
34	  When in doubt, say N.

39	default y
40	help
41	  Activate this option if your system contains a PCI to EISA
42	  bridge. If your system have both PCI and EISA slots, you
43	  certainly need this option.
44
45	  When in doubt, say Y.

52	depends on EISA && (ALPHA || X86)
53	default y
54	help
55	  Activate this option if your system only have EISA bus
56	  (no PCI slots). The Alpha Jensen is an example of such
57	  a system.
58
59	  When in doubt, say Y.

61config EISA_NAMES

63	depends on EISA
64	default y
65	help
66	  By default, the kernel contains a database of all known EISA
67	  device names to make the information in sysfs comprehensible
68	  to the user. This database increases size of the kernel
69	  image by about 40KB, but it gets freed after the system
70	  boots up, so it doesn't take up kernel memory. Anyway, if
71	  you are building an installation floppy or kernel for an
72	  embedded system where kernel image size really matters, you
73	  can disable this feature and you'll get device ID instead of
74	  names.
75
76	  When in doubt, say Y.
