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 an 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
