Setting The Cache Test And User Control Options; Setting The High Vertical Refresh Rate; Saving Your Settings - Epson NX Service Manual

Setting the Cache Test and User Control Options

Using SETUP, you can enable or disable the computer's internal cache (built into the
microprocessor) or external cache (built into an optional cache module). The default setting
for both cache options is Enabled.
Disable the cache if it malfunctions or if you are using timing-loop-dependent software that
requires a slower system speed.
Power-on diagnostic testing of the cache can also be disabled, if you are receiving cache
errors that prevent you from using the computer. The default setting is Enabled.

Setting the High Vertical Refresh Rate

SETUP allows you to set the vertical refresh rare for system screen resolutions. The default
rates and optional settings are shown in the table below:

Saving Your Settings

After you have made your selections for SETUP, press Esc to exit. You see the following
prompt:

Return to Setup
To save the settings in the CMOS RAM, highlight
To exit SETUP without saving your changes, press / to highlight No Save and Exit;
then press Enter. To remain in SETUP, select Return to Setup and press Enter;
the exit menu disappears.
Note You can also save your settings and remain in SETUP by pressing F1O any time in
the program. You see a message Changes Saved; then press any key and return
to SETUP.
If you saved your changes, the SETUP program resets your system and the computer
performs its power-on diagnostic tests (except if you are using the SETUP program on the
Reference disk).
If power-on diagnostics detects a problem, however, you see an error message and a prompt
to run SETUP. Follow the instructions on the screen to run SETUP again to correct it. (You
may need to turn the computer off and then on again.)
