Subject[PATCH] drivers/video/mdacon.c
This patch is against linux-2417/drivers/video/mdacon.c to get 
non-Hercules MDA working. Actually it does nothing, than assume a non
Hercules-MDA is compatible to "normal" Hercules. The current behaviour
is something confussing...

The problem whith the current version is, if you have such a
non-Hercules MDA it will detected while booting the kernel and you see a
message like "MDA with 8k RAM detected". Unfortunatley this message is
printed, but your card will _not_ be initialized, is it not recognized
as Hercules-compatible. So you will see the boot-message (and assume it
is working), but nothing on your MDA-console/monitor. So we have to
change this. It would be correct, to modify mdacon.c to _not_ print a
message about detecting a MDA is it not Hercules-compatible. But as i
mentioned above, at least my card is detected as non-Hercules but seems
fully compatible. So I would prefer, to consider any detected
non-Hercules MDA as Hercules-compatible. Please note, there is also some
special detection of "HerculesPlus" and "HerculesColor" in mdacon.c.
Does anybody know about any non Hercules compatible MDA ?

TiA,
Jan
