- 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!
