Removing an Option Card
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 illustration on page 3-17 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 installing another option card, replace the
option slot cover and retaining screw.
Adding Video Memory
Your computer comes with at least 512KB of video memory. If
you have 512KB of video memory, you can increase it to 1MB
by installing four video DRAM DIP (dual inline package) chips.
The chips must be 20-pin, 256KB, 80ns or 80ns. Additional video
memory is useful for running graphics-intensive applications
or for supporting high resolutions up to 1280 x 1024 in 16 colors
(interlaced) on your monitor. See Appendix A for a table
identifying supported colors and resolutions for each amount
of video memory.
Installing the Video Chips
You need to install four video DRAM DIP chips to upgrade the
memory. For the memory to work properly, you must install
one chip in each empty video memory socket on the system
board. Note that your video memory sockets may not look
exactly like the ones in the illustrations. If you are not sure how
to install video memory chips, contact the EPSON Connection.
