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.

21	  Say Y here if you are building a kernel for an EISA-based machine.

23	  Otherwise, say N.

42	  bridge. If your system have both PCI and EISA slots, you
43	  certainly need this option.

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