- In my C:\OS2 directory, I have found these files:
- OS2DASD.DMD OS2SCSI.DMD IBM1FLPY.ADD IBM1S506.ADD
-
- In config.sys file I have found these basedev:
- =PRINT01.SYS =IBM1FLPY.ADD =IBM1S506.ADD =OS2DASD.DMD
-
- Adaptec literature mentions two things I have not found:
- (1) AHA154x.add. (2) a basedev line in config.sys using (1).
-
- Q#1: Has anyone sayed that Toshiba 5200 controllers require bus
- mastering be disabled? Q#2: Can you see any solutions?
