# CONFIG_EISA configuration

config CONFIG_HAVE_EISA
	bool

menuconfig CONFIG_EISA
	bool "EISA support"
	depends on CONFIG_HAVE_EISA
	---help---
	  The Extended Industry Standard Architecture (CONFIG_EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The CONFIG_EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older CONFIG_ISA bus.  The CONFIG_EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the CONFIG_PCI bus.

	  Say Y here if you are building a kernel for an CONFIG_EISA-based machine.

	  Otherwise, say N.

config CONFIG_EISA_VLB_PRIMING
	bool "Vesa Local Bus priming"
	depends on CONFIG_X86 && CONFIG_EISA
	default n
	---help---
	  Activate this option if your system contains a Vesa Local
	  Bus (VLB) card that identify itself as an CONFIG_EISA card (such as
	  the Adaptec AHA-284x).

	  When in doubt, say N.

config CONFIG_EISA_PCI_EISA
	bool "Generic PCI/EISA bridge"
	depends on !CONFIG_PARISC && CONFIG_PCI && CONFIG_EISA
	default y
	---help---
	  Activate this option if your system contains a CONFIG_PCI to CONFIG_EISA
	  bridge. If your system have both CONFIG_PCI and CONFIG_EISA slots, you
	  certainly need this option.

	  When in doubt, say Y.

# Using CONFIG_EISA_VIRTUAL_ROOT on something other than an Alpha or
# an CONFIG_X86 may lead to crashes...

config CONFIG_EISA_VIRTUAL_ROOT
	bool "EISA virtual root device"
	depends on CONFIG_EISA && (CONFIG_ALPHA || CONFIG_X86)
	default y
	---help---
	  Activate this option if your system only have CONFIG_EISA bus
	  (no CONFIG_PCI slots). The Alpha Jensen is an example of such
	  a system.

	  When in doubt, say Y.

config CONFIG_EISA_NAMES
	bool "EISA device name database"
	depends on CONFIG_EISA
	default y
	---help---
	  By default, the kernel contains a database of all known CONFIG_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.
