IBM PC and PS/2 - Error codes

Applicable to: World-Wide

Service Information:
-- Error Codes and Beep Codes -- Revised 04/15/94

The Personal Computer has a habit of displaying error codes when first turned on (and at other times, too!). This listing, which consists mostly of error codes and sounds that are displayed during POST (Power-On Self-Test) may be of use to users in problem determination. If you don't find the exact error code you're looking for, try looking for the first few non-zero digits of the code.

Note:
This is not generally a complete or definitive list of codes. If you don't find what you're looking for here, try the relevant Hardware Maintenance and Service Manual (if you can find one).

| Recent changes to the list are marked with a bar.

Notes:
BEEP codes that may occur during POST (Power-On Self Test):

Beeps Failure
==========================================
No display and No beeps Power
Continuous Beep Power
Repeating Short beeps Power or stuck keyboard key
1 long and 1 short high beep Clock speed too fast
1 long and 2 short beeps Display
1 short beep Display
2 short beeps Display
1 long and 3 short beeps EGA -- check the video RAM

The power-on routines for the PC Convertible use similar audible signals :-
- One short beep: No errors found
- Two short beeps: Nonfatal errors found
- One long and one short beep: Fatal errors found
- One long and two short beeps: Fatal errors found; LCD controller
failed, or, if LCD is detached, CRT display adaptor failed.
- Three short beeps: Low battery without external power (fatal error)
- No beeps: The power-on self-test routines could not run, speaker failed.

For a 90 or 95 with no beep, fan runs, power-on light lights, memory count
and blinking curser continuously loops, suspect Processor Board Cache

A long beep followed by two short beeps on POST indicates that the primary display adapter is malfunctioning. The first thing to check is the switch settings to be sure that they are set properly for the display adapter(s) installed. If the switches are correct the primary display adapter is probably bad, and needs to be replaced.

An audible click at power-on indicates "power-good". A click followed by no beeps, means power-good, but cannot run POST.

ROM BIOS TEST.08 (Page A-12 in an early Tech Ref) describes the Display Adapter tests in detail. For the mono display adapter, the 4K bytes of display memory at B0000 are tested, then the set/reset of two CRT interface lines (Video Enable and Horizontal Sync) are checked. Any failure will cause one long and two short beeps. You can tell if the memory portion ran OK by seeing if (-STATUS SEL), pin 13 of U50, is made active in the second test.

All personal computer error codes for the DIAGNOSTIC and ADVANCED DIAGNOSTIC package are represented with the device number followed by two digits other than 00. The device number plus 00 represents successful completion of the test.

According to the PCC (PC Convertible) Tech. Ref. Vol 1, Appendix D, all Power-On Self Test test errors are depicted by an icon, error code or both.
Time and date errors -- PC Convertible

Errors such as time or date not set are indicated by an icon. The time/date not set icon means that the real-time clock value is not valid, because it has never been set or that the system has lost standby power.
Low battery warning -- PC Convertible

The power-on and BIOS routines provide functions to monitor the condition of the battery. If a low-battery condition is detected and external power is not being supplied during power on, the power-on routines issue three short beeps through the speaker and then power-down the system. If a low-battery condition is detected and external power is being supplied during power on, either a low-battery icon is displayed prior to an IPL or two short beeps are issued before an application resumes.

If during normal operation, the low-battery warning is enabled, a low- battery condition is detected, and the system is operating without external power, BIOS issues three short beeps through the speaker, causes the LCD screen to blink off and on at 1-second intervals, and stops all main level processing. This stops all noninterrupt-driven processing; however, interrupt-driven processing continues. When a key on the keyboard is pressed, the screen stops blinking and main-level processing is resumed. If the low-battery condition remains and external power is not supplied, the low-battery warning is repeated every 2 minutes. If keyboard activity does not occur or if external power is not supplied to the system unit within the 2 minutes, BIOS automatically suspends the application and powers off the system in order to conserve power.

If external power is supplied during the warning, the blinking stops and normal processing is restored.
There are (at least) three non-Diagnostic or POST errors which are included :-
1. Internal Processing Error -- Message issued by OS/2 DOS box when a program running in the DOS box corrupts the DOS environment.
2. 113 DOS Internal Stack Overflow -- DOS error *not* POST or Diagnostics You may be able to make the 113 go away by making a non-resident program resident
3. C0000005: is from OS/2 2.0, the "BVHSVGA.DLL" file should be replaced. Page 14 of the OS/2 Tips and Techniques document has some information on the error.

Another common cause of the C0000005 error -- you have an advanced video adapter (8514/A, XGA, Image Adapter) installed and configured under OS/2, but your display is plugged into the planar VGA port. Typically, this error is seen immediately after moving or recabling your system.

OS/2 Trap 2 errors (spurious NMI or adapter parity check error): Replace memory options until fixed; if unsuccessful, replace motherboard.

Trap reports seem to follow the Intel exceptions fairly well. This doesn't help much for a Trap 0002, but for the others, the registers AX, BX, CX, etc are the values in those registers at the time the exception occurred.

CSLIM, DSLIM, ESLIM, SSLIM are the maximum (minimum for SSLIM) addresses that are valid for the segment descriptor in the register, i.e. the segment limit defined in the descriptor table.

CSACC, SSACC, DSACC, ESACC are the access codes from the segment descriptors. The format for a data descriptor access code is :-

|A|W|ED|0|1|DPL|P| (DPL is two bits, the others are one bit each)
------------------
where A is the accessed bit
W is the writeable bit
ED is the expansion direction bit
DPL is the Descriptor Privilege level
P is the present bit

The format for a code descriptor access code is
|A|R|C|1|1|DPL|P| (DPL is two bits, the others are one bit each
------------------
where A is the accessed bit
R is the readable bit
C is the Conforming bit
DPL is the Descriptor Privilege level
P is the present bit

ERRCD, ERLIM, ERACC
Exceptions that might involve a particular segment push a error code onto the stack. If the error code is not zero, it is interpreted as follows :-

| EX | I | TI | INDEX |
-----------------------------

The EX (external) bit is set when the problem is not a task problem (usually a system problem, not a software problem).

The I (IDT) bit is set if the INDEX refers to an interrupt gate descriptor. If the I bit is set, ignore the TI bit, if reset the TI bit identifies the GDT or the LDT as containing the problem selector (TI set => LDT).

The INDEX identifies the selector (if any) that is associated with the exception.

ERLIM and ERACC are apparently the access code and limit for the suspect selector.

CS:IP usually points to the failing instruction. For some exceptions it will point to the next instruction, and for some the CS:IP is totally unrelated.

Trap exception CS:IP pts to error code
----- --------- ------------ ----------
0 Divide error failing inst NO
1 Single step next inst NO
3 Breakpoint next inst NO
4 Overflow next inst NO
5 Bound chk failing inst NO
6 Bad opcode failing inst NO
7 Processor ext unrelated NO
not available
8 Double fault failing inst Yes (but it's always 0
9 Processor ext unrelated NO
segment overrun
A Invalid TSS failing inst YES
B Seg Not Present failing inst YES
C Stack Exception failing inst YES
D General Protection failing inst YES
10 Processor ext unrelated NO
error

The reason that the TRAP 002 display doesn't help much is that it is not an exception condition. It is the NMI (Non-maskable interrupt) for the processor. This condition is raised whenever a piece of hardware places a signal on the NMI pin on the chip and is used to report hardware failures. Since the condition is not raised by the processor, the above information doesn't mean much. The executing instruction may have no relation to the faulty memory. (For example if the 80287 accesses memory and triggers a parity error while running in parallel with the 80286, the CS:IP doesn't point to the instruction that raised the NMI.)

The Trap 002 attempts to remedy this by displaying a "location", but from the example that Joe sent me, it appears that it displays it in selector:offset format. If this is the case, the location isn't very useful since a selector can point to any memory in the machine.

Trap E is a page fault (i.e., referencing a page that is not present). Trap 0418 "memory error on adapter card" but diagnostics can't find it but wiggling one of the motherboard memory cards on a Model 80 seems to have fixed it for now.

General Troubleshooting procedure :-
1. Boot the Advanced Diagnostics and run all the diagnostics. You are looking for 2 things in particular: memory errors and adapters that are not known to the diagnostics.
2. Assuming that the diagnostics find nothing (quite likely), remove all adapters except the display card and the FD/HD controller, re-run SETUP (if necessary), and try both cold and warm boots. Warm boots probably work OK now.
3. Put back the other adapter cards, one at a time, doing the cold and warm boot test after each. Either you will find one of the conflicting cards, or all of this activity will scare away the gremlins that were causing the Parity 2 (or other) checks.

SYSxxxxx errors (where xxxxx are digits, as in SYS02025) are usually OS/2 error codes. If you installed the OS/2 on-line help files, you can type 'HELP SYSxxxxx' in an OS/2 window, and you will get help on that error code if it is documented.

I999001X Invalid hard disk Initial Microcode Load record
A valid master IML record was not found on the hard disk
I9990015 on a 90 or 95 followed by 96-8N1 means that the system could find no
output display. Check that cable is connected.
I999002X Hard Disk Initial Microcode Load Record Load Error
I999003X Incompatible Disk Initial Microcode Load Record/Planar. The Initial

101 Main system board failure/Processor error.
PS/2 - Interrupt failure
PCC - Interrupt controller failure
102 BIOS ROM checksum error. (Try reseating the ROM chips!)
PS/2 - Timer failure or Real time clock 64 byte CMOS RAM test
PCC - System timer 2 failure
103 BASIC ROM(s) checksum error.
PS/2 - Timer interrupt failure or 2Kb CMOS RAM test
PCC - System timer 0 failure
104 8259 interrupt controller error.
PS/2 - Protect mode failure or Real time clock timing test
105 8253 timer error.
PS/2 - last 8042 command not accepted
PCC - DMA controller failure
106 (PS/2) Converting logic test failure
107 Interrupt failure on 339 AT
Remove cards one at a time until you find the failing adapter.
If problem persists after all cards except Fixed Disk adapter,
or the primary display adapter, then the system board is failing.
PS/2 - Hot NMI test
108 (PS/2) Timer bus test
(PCAT) Memory error, or memory too slow for CPU
109 Direct memory access test error
PS/2 - Low meg chip select test or DMA or arbitration error
110 (PS/2) Planar parity
111 (PS/2) I/O parity or 80286 type protect mode test
-- POSSIBLE IMAGE ADAPTER error if (See 20000 series messages)
111/???? is a Channel I/O Ready line problem with the 5250 emulation card. A
new ADF file for the card is necessary. It should be version 1.01, not 1.00

What 111 really means is that an NMI was signalled and the source
was the IOCK line (on PC) or the CHCK line (on MicroChannel).

On PCs, this was pulled by parity error detected on memory expansion
cards. On MicroChannel PS/2s, there may be other cards which pull this
error line active for other reasons.
If you have a memory expansion card, this is very likely to be the source.

The system BIOS cannot determine what card caused the problem.

Possible fix -- replace 3 chip SIMMS with 9 chip SIMMS (especially for OS/2)

112 (PS/2) Watchdog time out or Test 80386 new extended registers
113 (PS/2) DMA arbitration time out or Test 80386 new instructions
The hard disk drive may have to be replaced
There is a Retain reference for the PS/2 model 55: H064377

NOTE: "0002 1130" is basically a "211" error code, which is a memory error
on the planar. The "3" indicates SIMM socket A2 (1=A1,2=B1,3=A2 etc) and the
last character ("0") gives the SIMM speed.

Alternately this could be a DOS error -- see above on internal stack overflow

Also, it is possible that a PS/2 113 error can arise from certain
programming routines used with a Soundblaster MCV.

114 (PS/2) External ROM checksum error or Test 80386 32-bit addressing mode
115 (PS/2) Test 80386 protect mode (80386 TSSs, VM8086, Paging)
116 (PS/2) Test 80386 16/32 bit (mult., div., sub., add)
118 (PS/2) Logged memory error - run Adv Diags (90 and 95)
119 (PS/2) 2.88MB diskette drive is installed but not supported
120 (PS/2) Processor self test failed
121 Unexpected hardware interrupts occurred.
(PS/2) Test Hot reset of processor (via port 90H)
129 (PS/2) Processor has been changed. Run Configuration.
0129 1200 means that a watchdog timeout occurred. This usually indicates
(1) a runaway application or (2) an errant system board.
0129 1300 Indicates that a MicroChannel bus timeout has occurred -- see 12913

131 Cassette wrap test failed.
PS/2 - Test DMA compatibility registers
132 (PS/2) Test DMA extended registers
133 (PS/2) Test DMA verify logic
134 (PS/2) Test DMA arbitration logic

141 PS/2 - System-status display assembly. 80% chance it's the system board

151 SYSTEM BOARD Real Time Clock Failure (or CMOS ERROR on 5170 -- PC/AT)
152 (PS/2) Real time clock or CMOS error -- run diagnostics from a cold boot
WITHOUT a password installed -- you can get a 152 error when trying to test
the LOCKED area of the CMOS Real-Time Clock chip that CONTAINS the password.

(Try it with the password removed, and from a cold-boot. If you still
get a 152, you might have to replace either the battery or the planar)

153 (PS/2) Battery failure
160 (PS/2) Planar ID not recognized
(Check that the I/O channel riser card is firmly plugged in)
161 AT systems options not set (run SETUP)
PS/2 - Battery dead or not connected
162 AT systems options not set (run SETUP) << See 164
PS/2 - Systems options not set (Run Configuration)
163 AT time & date not set (run SETUP)
PCC - Real-time clock not updating
164 AT memory size error -- To correct it, run SETUP on Diagnostics Disk
PS/2 - Memory Size error (run Setup on Reference Disk)

Make sure that external units (like disk drives) are powered on before
powering up the system unit -- you may want to leave your external drive on

"System options are not set" means that "the configuration stored in the CMOS
doesn't match reality" but also that the code thinks that the rest of the
system is usable - and will run diagnostics for whatever it can find - memory
check, drive check, etc.

Computers are unreasonable, so minor details can cause major trouble.
You'll need the installation ("options") diskettes for any extra hardware
that's been added (modems, etc.).

165 PS/2 - systems options not set - card ID mismatch (run SETUP)
166 PS/2 - card busy error
167 PS/2 - clock not updating
If you are continually losing SETUP data, it means either the battery is
low or not connected in some way OR the system board CMOS memory is defective
which requires getting the system board replaced. It nearly always is the
battery or the battery connections.

168 - PS/2 model 55 -- a medialess box with a faulty RIPL ROM.
169 (PS/2) Planar/processor card mismatch (Run SETUP)
170 (PCC) LCD not in use when suspended (possible operator error)
(PS/2) ASCII setup conflict

On a PS/2 Mod 80 if you remove the memory card from a configured system and
plug it into the 'other' slot (either by mistake or deliberately), you will
get a 215/216 error during POST. You will not be able to run SETUP.
Fix the problem by moving the card back to the other slot.

If you really want to change the position, you will either have to disconnect
the battery (for a long time) or configure the machine with TWO memory cards
and then remove the one that you don't want and reconfigure it with one
again.

1811 Extender card wrap test failed (disabled).
1812 High order address lines failure (disabled).
1813 Wait state failure (disabled).
-*-1813 and 1815-*- There is an EC to the expansion card which
resides in the system unit. The modification is in the upper
left hand corner (component side); one trace is cut on the
printed side and one wire add component side.
1814 Enable/Disable could not be set on.
1815 Wait state failure (enabled) -- See 1813 note above
1816 Extender card wrap test failed (enabled).
1817 High order address lines failure (enabled).
1818 Disable not functioning
1819 Wait request switch not set correctly

This error condition is noted whenever either (1) there is RAM in the
SU 64K or more above the EU Switch setting or (2) if EU switches are
set for more than 640K. DMA errors can result if there is any SU RAM
above the switch settings.

Put all memory and memory expansion cards in the system unit with the
display adapters and the async adapter in the expansion box.

SU switch settings of OFF ON OFF ON (640K) are fine for all normal
system configurations including configurations of less than 640K

2201 Cluster Adapter Failure

23xx Plasma Monitor Adapter

24xx EGA or VGA or L40SX LCD display
2401 Enhanced Grahpics Adapter Failure
2401 (PS/2) Planar video error -- it can be the display or the video.
First check for a solid connection -- wiggle the plug at the system end
and check for one or more bent pins

Next swap the monitor

If a 2401 error persists after swapping the monitor, then the system board
should be replaced next. However if your monitor serial number starts with
"72" , is below 72-0374000 and you cannot find the number "61" stamped on
the bottom of the display (you may need to remove the display stand), then
a replacement monitor will probably fix this error.

If it's definitely on the planar (ie another monitor fails) check the Inmos
palette DAC (ceramic DIP module with gold colored middle) for shorts between
the pins.

2402 (PS/2) Diagnostic video error
2408 (PS/2) VGA Ground Circuit Fault -- cord may be disconnected at system end
2409 (PS/2) VGA Ground Circuit Fault -- may be related to 8602 error
FIRST, check that you have DASDDRVR in config.sys. Then replace display; if
failure repeats during video diagnostics, replace the system board.

84xx Speech Adapter errors

8530 - IBM XMA (Expanded Memory Adapter).
Determine if the XMA card appears in your Installed Devices list when
running the diagnostics. If the list does not match your configuration
(either the list says the card is present, when it is not in fact present;
or the list says the card is not present when it in fact IS present), try
re-running SETUP (menu option 4) and see if the error goes away.

If the card is present and the list shows it, verify that the amount of
memory reported matches the amount of memory on the card. If it does not,
then perhaps you have the XMA and/or system board memory jumpers set
incorrectly. Also make sure that you have no other memory adapters
addressing the 256K-640K space.

The controller has found a sector on the disk with bad ECC. This is very
easy to cause. It is usually not a hardware failure. The only way to fix
the failure besides a reformat is to find the sector and rewrite it.
There is no need for a low level format; A DOS format should fix it.

????

It indicates that one of your adapter cards has pulled the -CHCK line,
NMI indicating that it has had an error of some sort. (This line goes to
the interrupt on the processor, which puts up this cryptic message.)
It is not easy to determine which card is at fault, or why.

20xyz Image Adapter/A error codes

All Image Adapter/A error codes are of a 20xyz format. The x variable
is defined as follows:
200yz; x = 0 - Original Image adapter card error code
201yz; x = 1 - Original Image adapter card plus daughter card error code
204yz; x = 4 - Later Image adapter card error code
205yz; x = 5 - Later Image adapter card plus daughter card error code

The yz variable is defined as follows :-

FATAL INTERNAL STACK ERROR -- DOS Problem (also reported as keyboard problem)
As documented in DOS 3.2's Appendix B, just add a command to your CONFIG.SYS
file: 'STACKS=18,256'. Default for stacks is 9,128. Doubling helps when
there are many hardware interrupts.

An error code via a blinking hard-disk light... can occasionally be
interpreted -- for example: On one brand of drive one short blink followed
by three long blinks is in fact an error indication generated by the drive
electronics. It indicates that the drive is "Not Ready" after failing to
"calibrate track zero" It usually means that the drive is dead or dying.
