1-8 Technical Information
The memory configuration consists of two banks (bank 0 and bank 1) with two sockets
each. The SIMM memory sockets accept 32-bit (non-parity) 4-, 8-, 16-, or 32-MB 60 ns
Fast Page (FP) mode SIMMs.
NOTE:
36-bit SIMMs may be used, but parity
bits are ignored.
The SIMMs are 1 MB x 32 bit (4 MB), 2 MB x 32 bit (8 MB), 4 MB x 32 bit (16 MB), and
8 MB x 32 bit (32 MB). When the standard SIMMs are removed, four 32-MB SIMMs may
be installed for a total of 128 MB.
CAUTION:
SIMMs must match the tin metal
plating used on the system board SIMM sockets.
When adding SIMMs, use tin-plated SIMMs.
SIMMs install directly in the four sockets on the system board. The four sockets are
assigned as Bank 0 (2 sockets) and Bank 1 (2 sockets). All configurations have two SIMMs
are installed in bank 1. SIMM banks can be populated in either order.
SIMMs must be installed in pairs of the same memory type and size. Both sockets must be
populated within a bank for the system to work. No switch or jumpers are required to set
when the memory is changed. The system BIOS automatically detects the SIMMs. See
“Checking the Memory in the System” in Section 3 for the valid configurations.
Interrupt Controller
The interrupt controller operates as an interrupt manager for the entire system environment.
The controller accepts requests from peripherals, issues interrupt requests to the processor,
resolves interrupt priorities, and provides vectors for the processor to determine which
interrupt routine to execute. The interrupt controller has priority assignment modes that can
be reconfigured at any time during system operations.
