Do you have a 2.5" to 3.5" adapter?

CD means drive C (master/primary) or drive D (slave/secondary) It seems like you have to install the jumper to short both right pins.

Considering the 2.11 BIOS work flawlessly with everything except the 73GB drive, I'm not convinced there is a hardware incompatibility. If there were, I don't think it would be working perfectly with my 9 and 4GB drives. Too bad we cannot debug your system remotely (by using a terminal and a RS232 …

Perhaps this is a socket for a dirty tag ram or the configuration with 2x 8K tag chips.

Since pipelined burst cache is what makes a Pentium fly, I don't recommend to use any boards with asynchronous L2 cache.

Naturally. Anyone happen to know offhand a DOS utility to expand an existing FAT32 partition? You don't just edit the size of your FAT32 partition. You will probably alter file system type too. There is a difference between FAT32 (CHS) = type 0Bh and FAT32 (LBA) = type 0Ch. In your place I'd do a …

Do BIOS and SCSI driver support disks > 8 GB too? Try an Adaptec 2740/2742 in narrow or wide version instead. mkarcher has patched BIOS + ASPI7DOS driver to even get past 8 GB.
