13 The Extended Industry Standard Architecture (EISA) bus was
14 developed as an open alternative to the IBM MicroChannel bus.
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.
25 config EISA_VLB_PRIMING
26 bool "Vesa Local Bus priming"
27 depends on X86 && EISA
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).
37 bool "Generic PCI/EISA bridge"
38 depends on !PARISC && PCI && EISA
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.
47 # Using EISA_VIRTUAL_ROOT on something other than an Alpha or
48 # an X86 may lead to crashes...
50 config EISA_VIRTUAL_ROOT
51 bool "EISA virtual root device"
52 depends on EISA && (ALPHA || X86)
55 Activate this option if your system only have EISA bus
56 (no PCI slots). The Alpha Jensen is an example of such
62 bool "EISA device name database"
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
