Appendix B. POST Messages
POST Messages
During the Power On Self Test (POST), if the BIOS detects an error requiring you
to fix something, 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 three short beeps. The other code indicates that a 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

70
Checksum of CMOS is incorrect. This could mean 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 setting different to the one 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.
DISPLAY TYPE HAS CHANGED SINCE LAST BOOT
Since last powering off the system, the display adapter has been changed. You
must configure the system for the new display type.
EISA Configuration Checksum Error
PLEASE RUN EISA CONFIGURATION UTILITY
The EISA non-volatile RAM checksum is incorrect or cannot correctly read the
EISA slot. This can indicate either the EISA non-volatile memory has become
corrupt or the slot has been configured incorrectly. Also be sure the card is
installed firmly in the slot.
EISA Configuration Is Not Complete
PLEASE RUN EISA CONFIGURATION UTILITY
The slot configuration information stored in the EISA non-volatile memory is
incomplete.
Note: When either of these errors appear, the system will
boot in ISA mode, which allows you to run the EISA
Configuration Utility.
