This implies that the "SiliconExpress" driver we commonly use with the SE-IV is the correct control panel for this card as well, since the A/V Utility is the same between the two.
It also implies that the SE-III existed, but was actually just the differential-SCSI version of the SE-II.
I'm guessing the SE-II is a disk-controller-only board much like the SE-IV. If so, you might get some luvvin from the formatting utilities on my website.
