Extended Industry-Standard Architecture
EISA

    (EISA) /eesa/ 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.
