Last Updated: January 14, 1995

Symptoms
Workplace Shell is corrupted or does not come up upon booting OS/2. OS2.INI and OS2SYS.ini files become corrupted.

Hardware
Promise Technologies, Inc. DC4030VL-2 IDE caching controller card

Problem
The above mentioned caching controller card, when used in conjunction with the Promise Technologies PTI1S506.ADD device driver and OS/2 installed on a HPFS partition, will not correctly write the OS2.INI and OS2SYS.INI files to the \OS2 subdirectory. The following procedure assumes that your system consists of both FAT and HPFS partitions.

Procedure
A solution to this is to copy your OS2.INI and OS2SYS.INI files to a subdirectory on a FAT partition. Then in your CONFIG.SYS file for OS/2, edit the following lines to correctly reference the files in their new position, i.e.

Using a FAT partition D: and the files placed in \OS2 subdirectory ....

SET USER_INI=D:\OS2\OS2.INI SET SYSTEM_INI=D:\OS2\OS2SYS.INI
