Modifying the System Board

Installing Video Memory

The following sections provide procedures for upgrading
and configuring the system board in your system. Topics
covered include:
Installing video memory DRAMs
Replacing the Non-Volatile Memory
Replacing the real-time clock battery
Installing or removing a processor
Installing or removing DIMMs.
Notice: Electrostatic discharge (ESD) can damage add-
in boards and other components; place them on an
antistatic surface. Modify the system board only at an
ESD workstation. Otherwise, wear an antistatic wrist
strap attached to chassis ground.
The base system includes two 512K video memory
DRAM chips and two sockets on the system board. If
you add two additional 512K video memory DRAMs into
the sockets shown in Figure 4-2, the base video memory
size is increased from 1 MB to 2 MB.
Notice: Observe static precautions. Use an antistatic
wrist strap.
1. Power off the system and remove the side panel as
described earlier in this chapter.
2. Align the beveled edge of the DRAMs with the
notched corner of the DRAM sockets. Refer to Figure
4-2 for the DRAM socket locations.
3. Press the DRAMs down firmly until they are fully
seated in their sockets.
4. Replace the side panel and power on the system.
