Re: Problems with a S3 Card

Hi !

handbook never tell the truth :-).

Yes - otherwise it would complain.

That is the actual problem. This might be related to using the VGA dac
driver, but I am not sure.

BTW (for Jon): this translates to "Device or ressource busy".

Yes - The VGA clock/ramdac drivers cannot handle the MMIO mode or e.g.
VRAM devices. They work when in VGA compatibility mode, but when you take the
card into their "native" operating mode, they cease working, because things
work differently then, and this needs to be set up in these devices, too.
