Expanding Your Server

Installing Video Memory
The server’s main logic board comes with 512 KB of onboard video
memory. Increasing the video memory buffer size to 1 MB by installing
a 256 K x 16,
70 ns fast-page video DRAM chip enables the video controller to support
132-column text modes and high resolution graphics with 1280 x 1024 x
16 colors. Depending on the environment, the controller displays up to
64,000 colors in some video resolutions. To install video memory:
1. Turn off your server.
2. Disconnect external devices, ac power, and monitor power.
3. Unlock and remove left side panel.
4. If necessary, remove the CPU module from the CPU 1 (primary)
slot.
Refer to the CPU module removal procedures described earlier in this chapter.
5. Install the video DRAM chip. Make sure pin 1 of the video DRAM
chip is aligned with pin one on the socket (A, Figure 3-12).
6. If necessary, install the CPU module removed in step 4.
7. Replace and lock left side panel.
8. Connect external devices and restore power.
9. Run the SCU to configure your server for the additional video
memory.
Refer to Chapter 2, “Server Utilities,” for information on running the SCU.
