Promise Technologies, Inc. DC4030VL-2 IDE caching controller card
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.
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
The above procedure assumes that you're using the newest Promise Technologies device driver, version 1.41, dated 12-12-94. It is obtainable by calling the Promise Technologies, Inc. BBS at 1-408-452-1267 or by downloading the driver from various FTP sites (hobbes.cdrom.com and hobbes.nmsu.edu come to mind!).
For our controller BIOS setup, we have the Cache Mode set to ...
Turbo[Cache Enabled/Deferred Write]
and Disk I/O Handler set to ...
Turbo[DC4030VL-2 BIOS Remapped]
Remember to reset any ROM shadowing within the motherboard CMOS setup to account for the shadowing of the DC4030VL-2 BIOS.
We have been very pleased with the performance of this controller card within Warp, once the kinks were all worked out!
