Adding Video Memory

Your computer comes with 512KB of video memory soldered onto the main system board. You can increase your video memory to 1MB by installing four video DRAM, 20-pin, 70ns or Sons, 256KB x 4-bit, DIP (Dual Inline Package) chips. This is useful for running graphics-intensive applications or for supporting resolutions up to 1024 x 768 in 256 colors.

For the memory to work properly, you must install chips in one of the following configurations (each bank consists of two video memory sockets).

Video memory chip configuration

* Standard video memory

Installing the Video Chips

Follow these steps to install additional video DIP chips:

1.Locate the memory chip sockets on the main system board, shown on page 4-5.

Bank 0 contains two chips soldered onto the main system

board, so you cannot

add video memory in this bank. Bank

1 contains the two filled sockets closest to the soldered

chips. Bank 2 is the

two middle sockets and Bank 3 consists

of the remaining two

sockets.

2.If there is an option card in your way, remove it. See page 4-18 for instructions.
