Increasing the Video Memory

Your computer comes with at least 512KB of video memory. You can increase the video memory to 1MB by installing four 256K x 4-bit DRAM, 20-pin, ZIP (Zig-zag Inline Package) chips. This is useful for running graphics-intensive applications or for supporting resolutions up to 1024 x 768 or more on your monitor.

The following table lists the video DRAM ZIP chips that you can install on the main system board.

Installing the Video Memory Chips

You need four ZIPS to install the optional memory. For the memory to work properly, you must install one chip in each of the empty video memory sockets on the system board. Follow these steps:

1.Locate the memory chip sockets on the main system board, shown on page 4-3. The chip sockets you’ll use are the empty ones, numbered VMOO through VM03.

2.If there is an option card in your way, remove it. See page 4-19 for instructions.
