Adaptec 1542 and me: no joy

I borrowed an Adaptec 1542B to use in my machine for a while to see how things would go. Sadly, they don't go very well. I made a backup and then reformatted the disk using as suggested in the manual. Restored from backup, and everything was just fine. Everything would work just as it used to. Except when I pound on the disk reading and writing files. Then, BOOM---internal processing error. It seems that under heavy disk activity, the whole system is flakey. It causes some program to halt with access violations. When the disk activity stops, and I rerun the exact same program, everything goes just fine. Other times the whole thing stops with an internal processing error. Usually trap e at the same location. Some specifics: AHA1542B, default settings, except 5MB/sec DMA. Termination resistors removed. Mylex 386 motherboard Conner internal harddrive, SCSI ID 0, terminated. Archive tape drive, SCSI ID 4, external, terminated. Beta aha154x.add from Adaptec BBS. 12/92 version The SP aha154x.add was really flakey. The beta version was MUCH better---at least I can get some stuff done if I'm careful to single-task everything :-(. Does anyone have any suggestions and/or comments? Since the 1542 is such a popular controller, I have to believe it MUST work better than this. I'm doing something stupid I hope. Thanks for your help!

I have precisely the same symptoms as you describe, and with a similer environment -- only I have *two* IDE drives on my IDE controller, in addition to the SCSI drive. And I have a Wangtek tape drive. I have just about given up on getting the SCSI drive to work under OS/2 for now; I'm hoping that the 2.1 beta will behave better. Oh -- I do know this is not a hardware problem. The system works fine under DOS and Dell Unix. Sridhar -- M. A.

What I found was that the DMA speed on the adaptec was set from 5.0MB/sec to 5.7MB/sec. Changing it to 5.0MB did the trick. The jumper is J5 (I believe), pins 12 and 13 open. good luck... -- Todd Scalzott, Systems Programmer todd@kastle.com Kastle Development Associates ...!uunet!friend!todd

Uh oh! I have gotten a few of those TRAP E's, here. 1542B. OS/2 2.1b. I just assumed that it has nothing to do with disk access, and is simply some new OS/2 bugs :-( In article <sridhar.728173274@fir.cs.scarolina.edu> sridhar@cs.scarolina.edu (M. A.
