- I am trying to use Quantum 105mb SCSI drive in my 486 system that
- already has Microscience 65mb RLL drive. Both the drives have their original
- controllers. The probelm is that when I boot the system and the device driver
- for the Quantum drive (ATDOSIMP.SYS) is loaded, it generates an error saying
- "Drive #xxx of controller port #xx is not a quantum drive".I tried all the
- possible combinations of BIOS, I/O address and interrupt switches on the
- SCSI controller but it didn't work.
-
-
- Then I tried an IDE controller without IDE HD to drive my floppy
- drives and tried to boot the system again. Same problem showed up again.
- Notice that the drive works with both RLL and HD controllers in my 286
- machines without any problems.
-
- My 486 motherboard is using FOREX chipset. I don't know whether the
- problem is with the BIOS (AMI '91) or there is some hardware incompatiblity.
- If anyone has any solution for this problem, please let me know because all
- of my efforts are exhausted.
-
- Thanks.
- Zafar.
