The IBM ROM IML routine would have detected incompatible incompatible IML record. The ROM may not be an IBM ROM so the system access error is generated. I99906xx IBM overlay errors I99980xx ThinkPad system partition error 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 171 (PCC) Base 128K checksum failure (PS/2) Failed I/O addressing test - may be battery failure 172 (PCC) Diskette active when suspended (possible operator error) (PS/2) System Board 173 (PCC) Real-time clock RAM verification error (PS/2) CMOS checksum error (Run SETUP) 174 (PCC) LCD configuration changed (possible operator error) (PS/2) Bad configuration (Run SETUP) 175 (PS/2) Security error - the system board EEPROM failed 176 (PS/2) Security error - the tamper-evident switch was tripped. This usually means that the covers were removed without using a key 177 (PS/2) Security error - passwords corrupted 178 (PS/2) Security error - passwords corrupted 179 (PS/2) The system error log is full -- clear the error log 181 (PS/2) Boot error - no RIPL adapter or SCSI hard disk (ID 6) found 182 (PS/2) Privileged-access password jumper in wrong position 183 (PS/2) Must enter Privileged-access password, not power-on password 184 (PS/2) The power-on password is corrupted 185 (PS/2) The selectable startup sequence is corrupted 186 (PS/2) Security error 187 (PS/2) Vital Product Data (VPD) error - system serial number corrupt 188 (PS/2) VPD error -- run Automatic Configuration 189 (PS/2) The wrong password was entered 3 times.

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. 216 (PS/2) Base 64k on daughter card 1 card failed -- See comment on 215 above 217 (PS/2) Multibit ECC error 221 Machine error when copying the BIOS into RAM (8580-111 only). ROM to RAM remap error. An error occurred when the system checked the 128KB that was to accept a copy of the ROM. This is a latching error; once the error is detected, the system will no longer try to move the ROM to RAM until diagnostics (SETUP) are run to clear the error. 225 Some of your memory may be defective or not fast enough for your machine. 226 (PS/2) Memory error 231 EMO memory error indicating either a defective 80386 Memory Expansion Option card or defective memory module(s) on the EMO card. 235 (PS/2) Probable memory error, may be system/processor board 240 (PS/2) Memory error 241 Incompatible or unrecognized memory module installed on 80386 Memory Expansion Option.

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. 8601 (PS/2) System board error or mouse error 8602 (PS/2) User indicated mouse error--Include DASDDRVR.SYS in your CONFIG.SYS Load Reference Diskette and type A:INSTALL 8602 POST error may be a a bad mouse 8603 (PS/2) System board or mouse error 8604 (PS/2) System board or mouse error 8611 (Thinkpad) Keyboard pointing stick error 8612 (Thinkpad) Keyboard control card error 8613 (Thinkpad) System board error 89xx IBM Music card 91xx 3363 optical drive error: Reset cables and adapters Attempt F1 after error code and run Advanced Diagnostics. 9101 Optical disk -

Check installation of memory chips or run diagnostics to locate failing chip. 20005 20105 20405 20505; yz = 05 - Pixel interface test error 20006 20106 20406 20506; yz = 06 - CRTC test error 20007 20107 20407 20507; yz = 07 - Palette test error 20008 20108 20408 20508; yz = 08 - DAC test error. With 6091, check that IA/ output cable is not plugged into the 6091 outputs. 20010 20110 20410 20510; yz = 10 - Interrupt test error 20098 20198 20498 20598; yz = 98 - Bus mastership test error 20099 20199 20499 20599; yz = 99 - Slot test error Option Card Errors 20111 20511; yz = 11 - Scanner wrap test error 20112 20512; yz = 12 - Scanner serial to parallel shift test error 20113 20513; yz = 13 - Scanner line synchronisation counter test error 20114 20514; yz = 14 - Printer wrap test error 20115 20515; yz = 15 - Printer parallel to serial shift test error 20116 20516; yz = 16 - SCC Tx/Rx loop back test error 20117 20517; yz = 17 - SCC register test error 20118 20518; yz = 18 - External conditions and external interrupt test error 20119 20519; yz = 19 - Processor failed to stop 20008 Image Adapter failure -- Accompanied by Long-Short-Short Advanced Diagnostics error was 02000860 Check that outputs of the IA card are not hooked into the OUTPUTS of the 6091 POST and Image Adapter diagnostics are misleading DO NOT attempt to F1 past the POST error into OS/2. It will actually "work" but will rewrite your OS/2 .INI files for low-resolution operation. 10 - Interrupt test error 98 - Bus mastership test error 99 - Slot test error Option Card Errors 11 - Scanner wrap test error 12 - Scanner serial to parallel shift test error 13 - Scanner line synchronization counter test error 14 - Printer wrap test error 15 - Printer parallel to serial shift test error 16 - SCC Tx/Rx loop back test error 17 - SCC register test error 18 - External conditions and external interrupt test error 19 - Processor failed to stop 208xx Any SCSI device 242xx ISDN/2 Adapter 243xx XGA-2 Display Adapter 258xx System Board video failure ---------------END
