Phoenix BIOS Text Error Messages:

Diskette drive A errorDrive A: is present
but fails the POST diskette tests.  Check that the drive
is defined with the proper diskette type in Setup and that the
disk is installed correctly
Extended RAM failed
at offset: nnn
Extended memory not
working or not configured properly at offset: nnn
Failing Bits: nnnnThe hexadecimal number
nnnn is a map of the bits at the RAM address that failed the memory
test.  Each 1 in the map indicates a failed bit
Fixed Disk 0 FailureFixed disk is not working
or not configured properly.  Check to see if fixed disk is
installed properly.  Run Setup to be sure the fixed disk
type is correctly identified
Fixed Disk 1 FailureFixed disk is not working
or not configured properly.  Check to see if fixed disk is
installed properly.  Run Setup to be sure the fixed disk
type is correctly identified
Fixed Disk Controller
Failure
Fixed disk is not working
or not configured properly.  Check to see if fixed disk is
installed properly.  Run Setup to be sure the fixed disk
type is correctly identified
Incorrect Drive A:
type — run Setup
Type of diskette for
drive A: not correctly identified in Setup
Invalid NVRAM media
type
Problem with NVRAM
(CMOS) access
Keyboard controller
error
The keyboard controller
failed test.   Try replacing the keyboard
Keyboard errorKeyboard not working
Keyboard error nnBIOS discovered a stuck
key and displays the scan code nn 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 A: or C:.  Enter Setup and see if fixed
disk and drive A: are properly identified
Parity Check 1Parity error found
in the system bus.   BIOS attempts to locate the address
and display it on screen.  If it cannot locate the address,
it displays ???
Parity Check 2Parity error found
in the I/O bus.   BIOS attempts to locate the address and
display it on screen.  If it cannot locate the address, it
displays ???
Press <F1> to
resume, <F2> to Setup
Displayed after any
recoverable error message.  Press F1 to start the boot process
or F2 to enter Setup and change any settings
Real-time clock errorReal-time clock fails
BIOS test.   Might require motherboard repair
Shadow RAM failed at
offset: nnnn
Shadow RAM failed at
offset nnnn of the 64KB block at which the error was detected
System battery is dead

 

— Replace and run Setup

The CMOS clock battery
indicator shows the battery is dead.  Replace the battery
and run Setup to reconfigure the system
System cache error
— Cache disabled
RAM cache failed the
BIOS test.   BIOS disabled the cache
System CMOS checksum
bad — run Setup
System CMOS RAM has
been corrupted or modified incorrectly.  Perhaps by an application
program that changes data stored in CMOS.  Run Setup and
reconfigure the system either by getting the default values or
making your own selections
System RAM failed at
offset: nnnn
System RAM failed at
offset nnnn of the 64KB block at which the error was detected
System timer errorThe timer test failed.
Requires repair of system motherboard

Phoenix BIOS Post Procedures:

CPUCheck internal operations
i.e. ALE/IRQ status, Request, LA and memory read/write
CMOS RAMTest with walking bit
pattern
ROM BIOSPerform checksum on
ROM BIOS where all bits are added and compared to a factory set
total
PITCheck to ensure interrupt
requests are properly executed
DMACheck DMA from CPU
to memory without BIOS.  Also check page registers
Base 64KCheck first 4K block
Serial and Parallel
Ports
I/O data areas for
any devices found are assigned but are not tested
PICCheck that proper interrupt
request levels are addressed
Keyboard ControllerCheck 8240 for proper
operation, including scan code response and Gate A20 which allows
CPU operation in protected mode
CMOSCheck data within CMOS
and compare to BIOS information.  Failure of the extended
area is often due to wrong data setup.   Constant failure
after resetting CMOS is either battery CMOS chip or RTC
Video ControllerTest and initialize
controller and ROM on the video adapter
RTCCheck to ensure proper
frequencies are on proper lines for the Video Color CPU and DMA
frequency.  Check RTC and PIT or the system crystal if a
failure occurs
CPUReturn from protected
mode.  CPU is put into protected mode and returns to the
POST at the point indicated by the CMOS ROM data area byte 0F.
Failure here is normally due to the CPU, keyboard controller,
CMOS chip or an address line
PICTest counter 2
NMICheck for non maskable
interrupt request vector for active status.  Failure is normally
due to the CMOS but could also be the BIOS IRQ or CPU chips
KeyboardCheck for NumLock and/or
Caps and Shift keys
MouseInitialize through
the keyboard controller.  This is only done if a mouse ispresent and it is initialized in this way
RAM Above 64KTest in 64KB blocks
with a walking bit pattern and parity enabled
Fixed and Floppy ControllersTest for proper response
to BIOS calls
Shadow RAM AreasLook in CMOS for settings
on which adapter or system ROM’s are to be shadowed
Option ROMLook for ROM signatures
of 55AA in extended memory then initialize the ROM and halt testing
while internal checks are carried out
External CacheCheck controller chip
for external cache
CPU Internal CacheThe CPU’s internal
cache is tested
Hardware InterruptsInitialize and test
video, floppy, hard I/O adapters, serial and parallel ports
CassetteTest internal or external
cassette drives
Boot Code ErrorsErrors occurring after
this point are normally a corrupt boot record
