Each model includes an EISA system board that contains the
following major components:
The CPU (central processor unit) module plugs into the system
board and contains the appropriate processor. All the processors
come equipped with an integrated cache.
The system board contains four SIMM sockets that can
accommodate 2M, 4M, 8M, 16M, or 32M SIMMs. SIMMs must
be installed in pairs of the same size for a maximum onboard
memory of 128M.
The optional memory expansion module has eight SIMM sockets
that can accommodate 2M, 4M, 8M, 16M, or 32M SIMMs.
SIMMs must be installed in pairs of the same size for a
maximum expansion memory of 256M.
Total system memory is the combined total of system board
memory and optional expansion memory. The maximum total
system memory is 384M.
The 256K FLASH ROM (read-only memory) is divided into
system ROM (180K), EISA configuration (8K), BIOS recovery
(16K) , video BIOS (32K), BIOS Setup utility (8K), POST
(power-on self-test) (4K), and the user-defined region (8K).
