Installing The Cache Memory
Warning: SRAM chips are highly static sensitive de-
vices. Precautions should be taken to prevent static
damage to these components.
Installation Steps:
1. Locate U60 which is the connector for the
cache SRAM module.
2. Carefully insert the Cache module into U60.
Make sure to orient Pin 1 in the correct
position. Visually inspect the module to check
that it is properly installed into the connector
U60.
3. Set the jumpers for the new cache size. See
the tables below.
4. When the system is powered back on, setup
the Cache type (standard or Burst) and enable
the secondary Cache, in the CMOS, through
the BIOS SETUP.
Note: You can also setup secondary Cache to oper-
ate in Write-Thru or Write-Back mode.
