Table 5-2. BIOS Messages
Where nnnn is the amount of system cache in kilobytes successfully
tested.
Diskette Drive is present but fails the BIOS POST diskette tests. Check
to see that the drive is defined with the proper diskette type in Setup
and that the diskette drive is correctly attached.
The Setup program is starting.
Extended memory is not working or is not properly configured at offset
nnnn .
Where nnnn is the amount of RAM in kilobytes successfully tested.
The hex number nnnn is a map of the bits at the RAM address (in
System, Extended, or Shadow memory) which failed the memory test.
Each 1 (one) in the map indicates a failed bit.
Fixed disk is not working or not properly configured. Check to see if the
fixed disk is attached properly. Run Setup to be sure the fixed disk type
is correctly identified.
Type of floppy drive is not correctly identified in Setup.
Problem with NVRAM (CMOS) access.
The keyboard controller test failed. You may have to replace the
keyboard or controller.
The keyboard is not working. BIOS discovered a stuck key and displays
the scan code nn for the stuck key.
Unlock the system to proceed.
Monitor type is not correctly identified in Setup.
The operating system cannot be located on either drive A: or drive C:.
Enter Setup and see if the fixed disk and floppy are properly identified.
A parity error was found in the system bus (Parity Check 1) or the I/O
bus (Parity Check 2). BIOS attempts to locate and display the address
on the screen. If it cannot locate the address, it displays ????.
Displayed after any recoverable error message.
Optional message displayed during POST. Can be turned off in Setup.
Previous POST did not successfully complete. POST loads default
values and offers to run Setup. If the failure was caused by incorrect
values and they are not corrected, the next boot will likely fail. On
systems with control of wait states, improper Setup settings can also
terminate POST and cause this error on the next boot. Run Setup and
verify that the wait-state configuration is correct. This error is cleared
the next time the system is booted.
Real time clock fails BIOS test. May require board repair.
Shadow RAM failed at offset nnnn of the 64K block at which the error
was detected.
Where nnnn is the amount of shadow RAM in kilobytes successfully
tested.
The CMOS clock battery indicator shows the battery is dead. Replace
the battery and run Setup to reconfigure the system.
The system BIOS is copied to shadow RAM.
The RAM cache failed the BIOS test and BIOS has disabled the cache.
