For a system I built about a year and a half ago, it started (out of
the box) limiting the Ultra-Wide disks to 10MHz. I had to go into the
SCSI BIOS menus to enable the 20MHz speed for each target. It would
be nice (particularly for non-x86 platforms...) if the driver would
provide some way to do this for you..
