18281da177e4SLinus Torvalds	  The Extended Industry Standard Architecture (EISA) bus was
18291da177e4SLinus Torvalds	  developed as an open alternative to the IBM MicroChannel bus.
18301da177e4SLinus Torvalds
18311da177e4SLinus Torvalds	  The EISA bus provided some of the features of the IBM MicroChannel
18321da177e4SLinus Torvalds	  bus while maintaining backward compatibility with cards made for
18331da177e4SLinus Torvalds	  the older ISA bus.  The EISA bus saw limited use between 1988 and
18341da177e4SLinus Torvalds	  1995 when it was made obsolete by the PCI bus.
18351da177e4SLinus Torvalds
