Hello Xperts
Sorry I have made this post twice but I just noticed that my name
was not appearing on my posts. I fixed that thinking that folks
might not want to answer anonymous posts. Anyhow...
I have a general VGA question. I see from Ferraro\\\'s book that
the legacy port 0x3C2 (bit 7) reports on whether a vertical
retrace interrupt has occured. Is this bit cleared after reading
it so that it can be used properly in the case of shared interrupts?
Do most cards support this port and bit?
Thanks,
Daniel
