Controller UDMA/133

Disk UDMA/100

So we settle on UDMA/33 (which probably explains your slow disk
performance. Even if you were happy with 33MB/s the disk should end up
in udma5 mode which should make the bottleneck the disk not the bus (as
it in currently).

So probably failing to negotiate ATA/100 is the root issue, and would
explain the slow boot.

Does the BIOS let you force the IDE to start at ATA/100 rather than ATA/133?

Definitely an 80 pin cable?
