The
Extended Industry Standard Architecture (
EISA) is a bus standard for [IBM compatibles]
? that extends the
ISA bus architecture to 32
bits and allows more than one
CPU to share the bus. The [bus mastering]
? support is also enhanced to provide access to 4 GB of memory. Unlike
MCA, EISA can accept older
XT bus architecture and ISA boards.
EISA was announced in late 1988 by compatible vendors as a counter to IBM's MCA in its PS/2? series. Although somewhat inferior to the MCA it became much more popular due to the proprietary nature of MCA.
