6	bool

8menuconfig EISA
9	bool "EISA support"
10	depends on HAVE_EISA
11	---help---
12	  The Extended Industry Standard Architecture (EISA) bus was
13	  developed as an open alternative to the IBM MicroChannel bus.
14
15	  The EISA bus provided some of the features of the IBM MicroChannel
16	  bus while maintaining backward compatibility with cards made for
17	  the older ISA bus.  The EISA bus saw limited use between 1988 and
18	  1995 when it was made obsolete by the PCI bus.
19
20	  Say Y here if you are building a kernel for an EISA-based machine.
21
22	  Otherwise, say N.
23
24config EISA_VLB_PRIMING
25	bool "Vesa Local Bus priming"
26	depends on X86 && EISA
27	default n
28	---help---
29	  Activate this option if your system contains a Vesa Local
30	  Bus (VLB) card that identify itself as an EISA card (such as
31	  the Adaptec AHA-284x).
32
33	  When in doubt, say N.
34
35config EISA_PCI_EISA
36	bool "Generic PCI/EISA bridge"
37	depends on !PARISC && PCI && EISA
38	default y
39	---help---
40	  Activate this option if your system contains a PCI to EISA
41	  bridge. If your system have both PCI and EISA slots, you
42	  certainly need this option.
43
44	  When in doubt, say Y.
45
46# Using EISA_VIRTUAL_ROOT on something other than an Alpha or
47# an X86 may lead to crashes...
48
49config EISA_VIRTUAL_ROOT
50	bool "EISA virtual root device"
51	depends on EISA && (ALPHA || X86)
52	default y
53	---help---
54	  Activate this option if your system only have EISA bus
55	  (no PCI slots). The Alpha Jensen is an example of such
56	  a system.
57
58	  When in doubt, say Y.
59
60config EISA_NAMES
61	bool "EISA device name database"
62	depends on EISA
63	default y
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.
