OSVIBAS - HANDLING DISPLAY PROBLEMS IN OS/2 2.1 AND OS/2 2.11
02/05/96
=======================================================================
Handling Display Problems in OS/2 2.1 and OS/2 2.11
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
This document describes what to do when you experience intermittent
Desktop corruption or lockups when a folder repaints, either in VGA or
SVGA.
RESOLUTION
If the problem occurs in VGA resolution, run CHKDSK, and check for
hardware conflicts. Make sure the INI files are not damaged, and that
the SWAPPER.DAT file has free space.
1. Note which video mode you are in. If SVGA, switch to VGA using the
SETVGA command. If the same problem does not occur in VGA mode, it
is most likely a problem with video. If it does occur, the problem
could be a corrupted hard disk. Continue with the following steps.
2. Start the system with the OS/2 diskettes and go to the A: prompt. Do
NOT try to access the OS/2 drive.
3. Insert Diskette 2 in drive A.
4. For a file allocation table (FAT) system, type CHKDSK x: /F and
press Enter (x is the drive you suspect is corrupted).
For a high performance file system (HPFS), type CHKDSK x: /F:2 and
press Enter.
CHKDSK repairs a corrupted drive.
5. Remove the diskette; then restart the system.
6. Open an OS/2 session and change to the OS2\SYSTEM directory.
7. Make sure the SWAPPER.DAT file has at least 5 MB of free space (15 MB
is recommended). If the file does not have enough free space, you
must make room in the partition or move the SWAPPER.DAT file to a
different place on the drive.
8. Make sure the system BIOS is at the latest revision level. AMI BIOS
should be dated no earlier than 5/9/91. PHOENIX BIOS should be dated
no earlier than 5/11/92.
9. Make sure the INI files are not damaged. Check the OS/2 documentation
for instructions. Before you delete the OS2.INI or OS2SYS.INI file,
make a backup by renaming them. For example, rename OS2.INI to
OS2.BAD.
