3-6 Reviewing System Features
Memory can be installed in one socket or both. The memory
type, size, and speed can vary between sockets. The system
automatically detects the memory; no jumper settings are
required. The DIMMs can be either single- or double-sided.
The minimum allowable memory size for the system is
8 MB, and the maximum is 256 MB.
See Chapter 5 for DIMM option installation procedures.
The following table describes supported DIMM modules.
Supported DIMMs
DIMM TYPE CONFIGURATION TECHNOLOGY
8 MB CAS Latency 2 SDRAM 1 M x 64 16 Mbit
16 MB CAS Latency 2 SDRAM 2 M x 64 16 Mbit
32 MB CAS Latency 2 SDRAM 4 M x 64 16 Mbit
64 MB* CAS Latency 2 SDRAM 8 M x 64 16 Mbit
128 MB* CAS Latency 2 SDRAM 16 M x 64 64 Mbit
*64-MB and 128-MB modules are supported when available.
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.
