OS/2 Trap Messages
Trap Messages. Those OS/2 error messages that cause the weak to faint and the strong to cower. :{)>
Well, it's not THAT bad. Trap messages can be informative of a program that is misbehaving, or a hardware problem. Here is a quick table of trap messages from Gebran Krikor:
============================================================================== Trap # Function OS/2 HELP MSG (SYSxxxx) Likely cause under OS/2: ============================================================================== 0000 Divide error 3184 division by zero by OS/2 0001 Debug exception shouldn't occur 0002 NMI Interrupt memory parity or 387 error 0003 One Byte Interrupt shouldn't occur 0004 Interrupt on Overflow 3185 from INTO instruction 0005 Array Bounds Check 3191 from BOUND instruction 0006 Invalid OP-Code 3176 usually a corrupted .EXE 0007 Device not Available from ESC or WAIT instruction 0008 Double Fault shouldn't happen 0009 Reserved by Intel 000A Invalid TSS (Task State Segment) OS/2 bug - not a common bug 000B Segment not Present Can be a program or OS/2 bug 000C Stack Fault stack was ruined (not common) 000D General Protection Fault invalid pointer (most common) 000E Page Fault OS/2 bug, error in virtual mem 000F Reserved by Intel ============================================================================== (C)1992 Gebran Krikor * Freely distributable
And all is not lost. A CONFIG.SYS statement could be a big help for most TRAP errors. Add this line in your CONFIG.SYS and you get a text file named POPUPLOG.OS2 on the drive selected:
SUPPRESSPOPUPS=C
The misbehaving program is shutdown and OS/2 writes to the POPUPLOG.OS2. Most the information is generally of use to an IBM software Engineer or the author of the program.
Here is a sample entry from the POPUPLOG.OS2 from my system:
------------------------------------------------------------ 03-15-1997 22:49:02 SYS3175 PID 001d TID 0017 Slot 00b1 C:\OS2\PMSHELL.EXE c0000005 1f9a905a P1=00000001 P2=00001000 P3=XXXXXXXX P4=XXXXXXXX EAX=17921134 EBX=00001000 ECX=00000000 EDX=00001010 ESI=00000000 EDI=00000010 DS=0053 DSACC=d0f3 DSLIM=1fffffff ES=0053 ESACC=d0f3 ESLIM=1fffffff FS=150b FSACC=00f3 FSLIM=00000030 GS=0000 GSACC=**** GSLIM=******** CS:EIP=005b:1f9a905a CSACC=d0df CSLIM=1fffffff SS:ESP=0053:00d43f0c SSACC=d0f3 SSLIM=1fffffff EBP=00d43f40 FLG=00012206 SEAMLESS.DLL 0001:0000905a ------------------------------------------------------------
If you want further information, TRAP.ZIP contains an OS/2 INF file that lists all the OS/2 trap messages in more detail.
For a little fun, TRAPJOKE.ZIP is a joke program, that only displays a trap screen on an unsuspecting co-worker. (To get rid of the screen, DO NOT REBOOT! Use CTRL-C to clear the screen!) :{)>
Also here, is the full graphic image of a trap message, TRAP.BMP.
