Removing
You may need to remove an option card to access components
on the main system board-to change a jumper setting, for
example. You may also want to remove a card if you no longer
need it. Refer to the option card illustration on page 4-18 and
follow these steps:
1. Remove the retaining screw securing the option card to the
computer. Then pull the card straight out of the slot.
2. Set the card aside with the component side facing up.
3. If you are not replacing an option card, replace the option
slot cover and retaining screw.

Adding video Memory

Your computer comes with 1MB of video memory. You can
increase your video memory to 2MB by installing two video
DRAM, 256KB x 16-bit, 40-pin, ZIP (Zig-zag Inline Package)
chips. This is useful for running graphics-intensive applications
or for supporting high resolutions with many colors.
The following table lists the video DRAM ZIP chips you can
install on the main system board.
