Having some SCSI headaches here... I have a Miniscribe 8425S SCSI drive I want to use as boot disk.At 425MB it's by no means large, either for BIOS or for FAT16. Still, both DOS 6.22 and DOS 7.1 FDISK identify it as a 20MB drive. Regardless, I can format it to the full ~400MB net space and use it in DOS - but even though the single partition on it is set to active, I can't boot off it.
It's definitely not a size issue vs BIOS or DOS, as the same combination of motherboard and DOS 6.22 or 7.1 happily accept a Seagate ST3660A 660MB IDE HDD, detect its full size in FDISK and boot from it.
The SCSI drive is connected via an Adaptec AHA-1542C, which shows up during boot, initializes its BIOS and proclaims the 8425S as drive C:. For troubleshooting purposes I've removed all other I/O controllers in the system, it's just the MG TK8498F motherboard, a Miro Crystal 24S (S3 928 3MB VLB VGA) and this AHA-1542C. Only other drive is a Gotek on its floppy controller, which boots happily.
I'm pretty sure the problem is with incorrect partitioning, but can't figure out why it should be such a problem. Any tips?
