If the BIOS detects error 2C, 2E, or 30 (base 64K RAM error), it displays an additional word
of information reflecting the bit or address line that failed. For example, if "2C 0002" is
displayed, address line 1 (represented by bit one) has failed. If "2E 1020" is displayed, then
data bits 12 and 5 have failed in the upper 16 bits.
The BIOS sends the same information to the port 80h LED display. The check point code is
followed by a delay, the high order byte, another delay, and then the low order byte of the
error. This is be repeated continuously.
Warning Messages
The following is an alphabetic list of error and status messages which the PhoenixBIOS can
generate and an explanation of each message. Many of the messages below refer to the built
in Setup program.
Message
Description
nnnn Cache SRAM Passed
nnnn is the amount of system cache in kilobytes
successfully tested.
Diskette drive A error
Drive A: 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 attached correctly.
Entering SETUP
Starting Setup program
Extended RAM Failed at offset: nnnn
Extended memory not working or not configured
properly.
nnnn Extended RAM Passed
nnnn is the amount of RAM in kilobytes successfully
tested.
Failing Bits: nnnn
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 0 Failure or Fixed Disk 1
Failure or Fixed Disk Controller
Failure
Fixed disk is not working or not configured properly.
Check to see if fixed disk is attached properly. Run
Setup to ensure that the fixed-disk type is correctly
identified.
Incorrect Drive A type run SETUP
Type of floppy drive A: not correctly identified in
Setup.
Invalid NVRAM media type
Problem with NVRAM access.
Keyboard controller error
The keyboard controller failed test. You may have to
replace keyboard or controller.
Keyboard error
Keyboard not working.
Keyboard error nn
BIOS discovered a stuck key and displays the scan
code for the stuck key.
Keyboard locked Unlock key switch
Unlock the system to proceed.
Monitor type does not match CMOS
Run SETUP Monitor type not correctly identified in
Setup
Operating system not found
Operating system cannot be located on either drive
A: or drive C:. Enter Setup and see if fixed disk and
drive A: are properly identified.
Parity Check 1 nnnn Parity error
found in the system bus
BIOS attempts to locate the address but failed and
display it on the screen.
Parity Check 2 nnnn Parity error
found in the I/O bus
BIOS attempts to locate the address but failed and
