I got 54 emails from the linux-kernel list in 7 hours, including a Czech
guy who responded to my request for help with mda-con, asking if my card
is Hercules or generic. Generic. The others are mostly discussing
patches and kernel 2.6.6. Interesting if I could understand it.
I asked what portion of vgacon.c to copy over to mdacon.c so I could
compile with scroll buffer. Maybe it already has a buffer that works with
the original Hercules card only? There was some talk elsewhere about them
not being quite the same.
What a great community!
I need to set my spam filter to stop mails about patch or 2.6.
