Let me check tonight, I'll come back to you!

Also good to know, since I haven't used this mainboard earlier I've already checked for screw marks around the video port and I could't find any (in case the former owner used a longer screw to install the GDROM).

(I guess the last resort would be to heatgun the mainboard with solder flux on the DAC pins and video output port.)
