My Motorola PowerStack has an on-board Cirrus CL-GD5434-HC-B which I would like to disable as it can only manage 1024 x 768 x 16-bit colour.

After some checking I found Windows NT V4.00 SP2 has an S3 driver that worked with my S3 Vision 968 which can manage 1600 x 1200 x 16-bit colour.

When I install the S3 Vision 968 initially the post information is on the Cirrus and switches to the S3 968 part way through, but I would like the initial post information to be on the S3 968.

I have looked for jumpers on the motherboard and there don't seem to be any, also there does not seem to be an option in the ARC setup options to achieve this, anyway ARC get's run after the initial post has done all it's testing.
