DDC1: Good Stuff.

[Filip S. <fs...@st...>]

Great job Jos!

After a bit of tweaking of the Mach64 driver (mostly figuring out which of
the 16 general purpose IO lines is the one that I want) I got the DDC
driver to output this neato info:

And the monitor didn't catch on fire or anything! ;-)

Now I'd like to use this stuff to actually set a mode, but that might be a
bit of a slow going since as the luck would have it, the little old
monitor I use with my test-box does not support DDC, so now I have to use
my 19 in (actually the 36x27 cm, as the DDC info helpfuly points out)
for testing and use the 14 in for coding.

Anyways, keep up the good work!
