	  The ARM series is a line of low-power-consumption RISC chip designs
	  licensed by ARM Ltd and targeted at embedded applications and
	  handhelds such as the Compaq IPAQ.  ARM-based PCs are no longer
	  manufactured, but legacy ARM-based PC hardware remains popular in
	  Europe.  There is an ARM Linux project with a web page at
	  <http://www.arm.linux.org.uk/>.

	---help---
	  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.

config SBUS
