Hi Shane
I have the exact same combo. I have not jumpered pin 6 (force SE mode).
ALl I have is the scsi ID jumper(s) and pin 5 (enable auto spin up)
In the Adaptec bios (ctrl-A on boot) I have it se to 80 mb/sec
I couldn't even install on this combo with Red Hat 5.2, so it migh be that
you need a newer driver to get 80mb/s
