SETUP SYSTEM CONFIGURATION
A setup program has been built into the system BIOS so the configurations
stored in the CMOSRAM can be changed. This program should be executed
only after:
User has changed system configuration.
(1)
User has changed system backup battery.
(2)
System has detected a configuration error and has asked the user to run
(3)
the setup program.
After power-on RAM testing, the message: TO ENTER SETUP BEFORE
BOOT PRESS CTRL-ALT-ESC” is displayed on the screen. Press
“CTRL+ ALT+ ESC” to run setup or do nothing to bypass. If the
“CTRL+
ALT+ ESC” is pressed, the following message will be displayed:

STATUS PAGE SETUP
The setup program is completely menu-driven. Use the arrow keys to select
an entry; “+
/-”
keys to change an entry; and
“FlO”
key to exit. Help messages
are displayed in the window on the screen.
If this option is chosen then the screen above is displayed. System BIOS
automatically detects memory size, thus no changes are necessary. After the
changes are made, press
?I? 10”
to exit.
OPTIONS PAGE SETUP
The Options Page Setup program functions the same way as the status page
Setup, as shown below.
Users are not encouraged to run the status page Setup program, as your
system should have been fme tuned before shipping. Improper setup may
cause the system to fail, so consult your dealer before making any changes.
