3.2.16 Memory Setting

(1) DRAM Configuration

There are two 32-bit memory banks on the AR-B1462 board. It can be one-side or double-side SIMM (Single-Line

Memory Modules) which is designed to accommodate 256KX36 bit to 16MX36-bit SIMMs. This provides the user

with up to 128MB of main memory. The 32-bit SIMM (without parity bit) also can be used on AR-B1462 board.

There are listing on-board memory configurations available. Please refer to the following table for details:

SIMM1 SIMM2 Total Memory

256KX32(X36) None 1MB

(2) Cache RAM Select (JP10)

The AR-B1462 can be configured to provide a write-back or write-through cache scheme and support 512KB

cache systems. A write-back cache system may provide better performance than a write-through cache system.

The BIOS Setup program allows you to set the cache scheme either write-back or write-through, either the internal

cache selection.
