0013 The Extended Industry Standard Architecture (EISA) bus was
0014 developed as an open alternative to the IBM MicroChannel bus.
0015
0016 The EISA bus provided some of the features of the IBM MicroChannel
0017 bus while maintaining backward compatibility with cards made for
0018 the older ISA bus. The EISA bus saw limited use between 1988 and
0019 1995 when it was made obsolete by the PCI bus.
0020
0021 Say Y here if you are building a kernel for an EISA-based machine.
0022
0023 Otherwise, say N.

0030 Activate this option if your system contains a Vesa Local
0031 Bus (VLB) card that identify itself as an EISA card (such as
0032 the Adaptec AHA-284x).
0033

0041 Activate this option if your system contains a PCI to EISA
0042 bridge. If your system have both PCI and EISA slots, you
0043 certainly need this option.

0045 When in doubt, say Y.

0055 Activate this option if your system only have EISA bus
0056 (no PCI slots). The Alpha Jensen is an example of such
0057 a system.

0064 default y
0065 help
0066 By default, the kernel contains a database of all known EISA
0067 device names to make the information in sysfs comprehensible
0068 to the user. This database increases size of the kernel
0069 image by about 40KB, but it gets freed after the system
0070 boots up, so it doesn't take up kernel memory. Anyway, if
0071 you are building an installation floppy or kernel for an
0072 embedded system where kernel image size really matters, you
0073 can disable this feature and you'll get device ID instead of
0074 names.
0075
0076 When in doubt, say Y.
