BLOOOOOOPP!! Erazor 3 TNT2 coldstart is operational!! Wow! Small note: I probably need to really setup FIFO watermarks now, can't deny it anymore. Cards works beautifully as full secondary card in system in 640x480 8-32bit color, 800x600 8-16 bit color, and 1024x768 in 8 bit color (60Hz tested).

Go above that and you'll probably witness CRTC memory fetch errors (distortions, maybe like snow ;-)
