At these times (Windows 3.1x was the time for 1MB SVGA cards) we
also found video drivers by Diamond and Spea to be rather instable
for us. The problems were various, from lock ups in either full
screen or windowed DOS boxes, to incompatibilities with a secondary
video adapter in the same system (HGC) (for debugging), to strange
mouse effects. In our institution when then switched to only use
video cards based on Tseng Lab s ET4000 or ET6000 chips, or cards
manufactured by ELSA (usually were S3 based at these times), as
ELSA is known for extremely high quality of their drivers,
reliability, and good service. Probably also because we could
ask them directly in case of problems, since their headquarters
are located here in Aachen. (BTW. Some trivia: Although Elsa is a
rather old-fashioned girl s nick-name for Elisabeth, it actually just
means "Elektronische Sachen" here, that is "electronic devices". ;-)
Right now, I cannot remember any more, what it was exactly, but
many (older) Cirrus VGA chips don t supported some peculiarities
of the original VGA. During the K3PLUS development (aka FreeKEYB
now) I often had other non-Windows related video problems with
Cirrus based VGA designs, that s why I have come to avoid them
whereever I can...
