Appendix C – Power-On Self-Test Messages

POST Messages

During the Power-On Self-Test (POST) if the BIOS detects an error, 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

There are two kinds of beep codes in BIOS:
Single long beep followed by three short beeps—This code indicates that a video
error has occurred and the BIOS cannot initialize the video screen to display any
additional information.
Repeating long beep—This code indicates that a DRAM error has occurred.

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.

Table B–1. Error Messages
Cause/Solution
CMOS battery is no longer functional. It should be replaced.
Checksum of CMOS is incorrect. A weak battery may have caused this error;
replace if necessary. It may also indicate that CMOS has become corrupt.
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 (formatted as a boot device) 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, then reboot the
system.
Type of diskette drive installed in the system is different from the CMOS
definition. Run Setup to reconfigure the drive type correctly.
The display switch on the motherboard 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.
