I have a pentium 133 (or is it a 166) I forget, with that scsi controller
and I have no problems under 2.1.5.
I did have problems with lockups and panics when I first put it together -
the mother board is a triton HX, and there was a cmos jobber I had to turn
off - I cant remember exactly what it as called. Something to the effect
of Enable HX special features - or something close - the 'special
features' apparently are what was doing me.
I have 2 2940UW controllers, each running 2 4 wide giggers on a high
volume news server - they do not run any non wide units, or non disks.
