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

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

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

- Activate this option if your system only have EISA bus
- (no PCI slots).
- When in doubt, say Y.
- config EISA_NAMES
- bool "EISA device name database"
- depends on EISA
- default y
- help
- By default, the kernel contains a database of all known EISA
- device names to make the information in sysfs comprehensible
- to the user. This database increases size of the kernel
- image by about 40KB, but it gets freed after the system
- boots up, so it doesn't take up kernel memory. Anyway, if
- you are building an installation floppy or kernel for an
- embedded system where kernel image size really matters, you
- can disable this feature and you'll get device ID instead of
- names.
- When in doubt, say Y.
