I posted something earlier this week about how to take those first, tentative steps
down the slippery slope to VGA madness. To do any more than 640x480x[18] you need the
datasheets for the parts on the card: the VGA chip, the RAMDAC and the clock-generator.
You can often get by without any RAMDAC programming for resolutions up to 1024x768.
Sometimes there's more than one way for the VGA and clock-generator to interact and
although VGA cards from different manufacturers may contain the same major components,
they may require different initialisation sequences.
That's why I like the S3 Trio64 and Cirrus CL-GD54xx GUI chips, they contain the RAMDAC
and clock-generator too.
