OSOTHWRP - DURING STARTUP, SYSTEM HALTS WITH A TRAP0003
09/26/96
=======================================================================
During Startup, System Halts with a TRAP0003
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
During startup, the system halts with a TRAP0003.
This is usually caused by a corrupt PREVIOUS.DAT file existing either
in the root directory of the startup drive, or in the \OS2\BOOT
subdirectory of the startup drive.
The PREVIOUS.DAT file should reside in the \OS2\BOOT directory.
It is created or read at startup time when Hardware Detection is
enabled (which it is, by default).
If this file should become corrupt, the trap will occur during startup.
To disable Hardware Detection:
1. Restart the system.
2. When the OS/2 appears in the top left corner of the screen,
press Alt-F1 to bring up the Recovery Choices Screen.
3. Press F6 to disable hardware detection.
RESOLUTION
To repair or replace the PREVIOUS.DAT file and prevent the Trap error:
1. Insert the OS/2 Warp 4 Installation Diskette in drive A:,
then restart the system. Insert Diskette #1 and Diskette #2 when
prompted.
2. At the Welcome screen, Press F3 to get to a command prompt.
3. From the command prompt, locate the PREVIOUS.DAT file (either in the
root directory or in the \OS2\BOOT directory).
4. Either delete or (preferably) rename the PREVIOUS.DAT file.
5. Remove the diskette from drive A: and restart the system.
6. If Hardware Detection is enabled, a new PREVIOUS.DAT file will be
created.
Because PREVIOUS.DAT is ignored if hardware detection is disabled, no
new file will be created in this case.
You can turn Hardware Detection on and off follows:
1. Restart the system. When the small white rectangle appears in the
upper left corner of the screen, press Alt-F1 to get to the Recovery
Choices screen.
2. Press F6 to disable Hardware Detection, or,
Press F5 to re-enable to Hardware Detection.
