Removing an Option Card
You may need to remove an option card installed in your
computer 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. 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.
Adding Video Memory
Your computer comes with 256KB of video memory. You can
increase your video memory to either 512KB or 1024KB by
installing four or six video DRAM, 20-pin, 70ns or 80ns, 44256
DIP (Dual Inline Package) chips. This is useful for running
graphics-intensive applications or for supporting resolutions
up to 1024 x 768 on your monitor. See Appendix A for a table
identifying supported colors and resolutions for each amount
of video memory.
For the memory to work properly, you must install chips in the
following configuration (each bank contains two video memory
chips).
