Problems with QNX4 Demo and Savage MX


Does anyone know about problems with mode switching on a S3 Savage MX.

I have a notebook (ASUS 8400K) with an integrated Savage MX chipset. When
starting the QNX demo and choosing a 256 color graphics mode, it’s only
possible to change the resolution 1-3 times before the OS completely hangs.
I think the demo uses VESA-BIOS for mode-switching.
Does anyone know about such problems and/or how to solve?

Thanks in advance,
