With the cylinder limitation jumper unset, the BIOS hung during auto-detection, as expected for the Award 4.51PG BIOS. I tried applying the "hack" found at this site to my BIOS:
Specifically, I replaced the following bytes:
26 66 83 7d 78 ff 74 1a 26 81 7d 7a f0 0f 77 12
26 81 7d 7a f0 03 72 02 b2 ff 90 90 90 90 90 90
At first the patch seemed to work; the HD was detected as ~60 GB, 7476 Cyls, 255 heads, 63 Sectors/Cyl (LBA mode). However, PartionMagic and DiskEdit reported 29437 Cyls, 16 Heads, 255 Sectors/Cyl. As a result, I was able to create partitions initially, but was unable to subsequently modify them after creation using PartionMagic (due to a too-large cylinder number in the partition table); furthermore, Fdisk would report the drive's size incorrectly. Even stranger, the drive partition table would report my 60 GB drive as a 2 GB drive with some strange CHS parameters that I'd never seen before, although it would auto-detect properly! No matter how many times I auto-detected, the info in the drive table would revert to those weird numbers. These incorrect parameters would only show up when I had one or more partitions on the drive. Once I deleted the partition(s), the drive info went back to normal.
I hope I haven't given you way too much info. I appreciate any help you could give me. Thanks!
