Pressing "Y" stores the selections made in the menus in CMOS – a special section of memory
that stays on after you turn your system off. The next time you boot your computer, the BIOS
configures your system according to the Setup selections stored in CMOS. After saving the
values the system is restarted again.
Exit Without Saving
Pressing <Enter> on this item asks for confirmation:
Quit without saving (Y/N)? Y
This allows you to exit Setup without storing in CMOS any change. The previous selections
remain in effect. This exits the Setup utility and restarts your computer.
3-13 POST Messages
During the Power On Self-Test (POST), if the BIOS detects an error requiring you to do
something to fix, it will either sound a beep code or display a message.
If a message is displayed, it will be accompanied by:
PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP
POST Beep
Currently there are two kinds of beep codes in BIOS. This code indicates that a video error has
occurred and the BIOS cannot initialize the video screen to display any additional information.
This beep code consists of a single long beep followed by two short beeps. The other code
indicates that your DRAM error has occurred. This beep code consists of a single long beep
repeatedly.
Error Messages
One or more of the following messages may be displayed if the BIOS detects an error during
the POST. This list includes messages for both the ISA and the EISA BIOS.
CMOS BATTERY HAS FAILED
CMOS battery is no longer functional. It should be replaced.
CMOS CHECKSUM ERROR
Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This error
may have been caused by a weak battery. Check the battery and replace if necessary.
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
No boot device was found. This could mean that either a boot drive was not detected or the
drive does not contain proper system boot files. Insert a system disk into Drive A: and press
<Enter>. If you assumed the system would boot from the hard drive, make sure the controller
is inserted correctly and all cables are properly attached. Also be sure the disk is formatted as
a boot device. Then reboot the system.
DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP
Type of diskette drive installed in the system is different from the CMOS definition. Run Setup
to reconfigure the drive type correctly.
DISPLAY SWITCH IS SET INCORRECTLY
Display switch on the motherboard can be set to either monochrome or color. This indicates
the switch is set to a different setting than indicated in Setup. Determine which setting is
correct, and then either turn off the system and change the jumper, or enter Setup and change
the VIDEO selection.
