I'm using a CONTAQ/UMC VESA motherboard with a 66MHz DX2, Orchid Fahrenheit
VLB video card, UltraStor 34F LB SCSI.

I've had several problems - In windows I get lines left on the screen from
dragging large windows or cut boxes in Paint, occasionally areas of the
screen are filled with a pattern of dots, the mouse cursor occasionally
aquires a box that moves with it. Orchid claims this is a known UMC problem.

I have no problems with the disk or internal CD in windows or DOS, however
I have not yet been able to install NT yet. UltraStor is currently
looking into this.
