This is something that will have to be built into the video
controller. Perhaps opcode 4 should be a set sync mode operation with
the bottom eight bits being the sync mode bits:
7: reserved
6: reserved
5: reserved
4: reserved
3: hsync polarity (1 - positive, 0 - negative)
2: vsync polarity (1 - positive, 0 - negative)
1: composite sync
0: sync on green
Knew I was forgetting something. Yes we need two more bits for sync
polarity when using the NVRAM -- I hope that VGA/VESA and TV are standard.
