POWER ON SELF TEST MESSAGES
The following is an alphabetic list of error-and-status
messages that Phoenix BIOS and/or your operating
system can generate and an explanation of each message.
Error messages are marked with an *. The most
common errors are marked with a #. If an error message
is displayed that is not in this list, write it down and
check your operating system documentation both on
screen and in the manual. If you can find no reference
to the message and its meaning is not clear, contact
your support representative for assistance.
nnnn Cache SRAM Passed
Where nnnn is the amount of system cache in kilobytes
successfully tested by the Power On Self Test. (This can
only appear if you have an SRAM PC Card installed.)
*Diskette drive A error or Diskette drive B error
Drive A: or B: is present but fails the BIOS Power On Self
Test diskette tests. Check to see that the drive is defined
with the proper diskette type in the Setup Utility,
(See
BIOS Setup Utility page 29 for more information) and
that the diskette drive is installed correctly. If the disk
drive is properly defined and installed, avoid using it
and contact your support representative.
*Extended RAM Failed at offset: nnnn
Extended memory not working or configured improp-
erly. If you have an installed memory upgrade module,
verify that the module is properly installed. If it is prop-
erly installed, check your Windows Setup to be sure it is
not using unavailable memory until you can contact
your support representative.
nnnn Extended RAM Passed
Where nnnn is the amount of memory in kilobytes
successfully tested.
*Failing Bits: nnnn The hex number nnnn
This is a map of the bits at the memory address (in
System, Extended, or Shadow memory) which failed the
memory test. Each 1 (one) in the map indicates a failed
bit. This is a serious fault that may cause you to lose data
if you continue. Contact your support representative.
*Fixed Disk x Failure or Fixed Disk Controller
Failure (where x = 1-4)
The fixed disk is not working or not configured prop-
erly. This may mean that the hard drive type identified
in your setup utility does not agree with the type
detected by the Power On Self Test. Run the setup utility
to check for the hard drive type settings and correct
them if necessary. If the settings are OK and the message
appears when you restart the system, there may be a
serious fault which might cause you to lose data if you
continue. Contact your support representative.
*Incorrect Drive A type – run SETUP
Type of floppy drive A: not correctly identified in Setup.
This means that the floppy disk drive type identified in
your setup utility does not agree with the type detected
by the Power On Self Test. Run the setup utility to
correct the inconsistency.
*Incorrect Drive B type – run SETUP
Type of floppy drive B: not correctly identified in Setup.
This means that the floppy disk drive type identified in
your setup utility does not agree with the type detected
by the Power On Self Test. Run the setup utility to
correct the inconsistency.
*Invalid NVRAM media type
Problem with NVRAM access. In the unlikely case that
you see this message you may have some display prob-
lems. You can continue operating but should contact
your support representative for more information.
*Keyboard controller error
The keyboard controller test failed. You may have to
replace your keyboard or keyboard controller but may
be able to use an external keyboard until then.
*Keyboard error
Keyboard not working. You may have to replace your
keyboard or keyboard controller but may be able to use
an external keyboard until then. Contact your support
representative.
*Keyboard error nn
BIOS discovered a stuck key and displays the scan code
for the stuck key. You may have to replace your keyboard
but may be able to use an external keyboard until then.
Contact your support representative.
*Monitor type does not match CMOS – Run SETUP
Monitor type not correctly identified in Setup. This error
probably means your BIOS is corrupted, run the setup
utility and set all settings to the default conditions. If you
still get this error, contact your support representative.
#*Operating system not found
Operating system cannot be located on either drive A: or
drive C:. Enter the setup utility and see if both the fixed
disk, and drive A: are properly identified and that the
boot sequence is set correctly. Unless you have changed
your installation greatly, the operating system should be
on drive C:. If the setup utility is correctly set, your hard
drive may be corrupted and your system may have to be
reinstalled from your back up media.
*Parity Check 1 nnnn
Parity error found in the system bus. BIOS attempts to
locate the address and display it on the screen. If it
cannot locate the address, it displays ????. This is a
