bool "EISA support"
depends on HAVE_EISA
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.
bool "Vesa Local Bus priming"
depends on X86 && EISA
default 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.
bool "Generic PCI/EISA bridge"
depends on !PARISC && PCI && EISA
default y
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.
# Using EISA_VIRTUAL_ROOT on something other than an Alpha or
# an X86 may lead to crashes...
bool "EISA virtual root device"
depends on EISA && (ALPHA || X86)
default y
Activate this option if your system only have EISA bus
(no PCI slots). The Alpha Jensen is an example of such
a system.
When in doubt, say Y.
bool "EISA device name database"
depends on EISA
default y
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
When in doubt, say Y.
