Setting the Shadow RAM Function
A computer can access RAM (random access memory) faster than
ROM (read only memory). The Equity 386 provides a shadow RAM
feature that enables it to copy data from ROM areas in the computer
to the RAM area so it can perform certain operations faster. If you
enable the shadow RAM function through the Setup program, the
Equity 386 automatically copies the data stored in ROM to RAM
whenever you turn on or reset the computer.
Specifically, there are two ROM areas that can be copied to EXAM:
the system ROM BIOS and the video ROM. Enable both of these to
improve system performance and increase the speed with which your
screen displays text and graphics.
Follow these steps to enable (or disable) shadow RAM:
1. Highlight Shadow RAM and press Enter. You see this box:
If the displayed settings are correct, press t to return to the main
menu.
2. To enable shadow RAM for the BIOS, press Enter. You see
BIOS enabled.
3. To enable shadow RAM for the video, highlight VIDEO disabled
and press Enter. The line changes to VIDEO enabled.
4. Highlight ** SAVE SETTINGS ** and press Enter.
