I recently bought an EGA superset (NEC GB-1) and Multisync for my
PC Designs GV386. Since they aren't shipping yet, I put it in an
XT. There were problems which resulted from the "read pixel" function
of the BIOS returning zero frequently. This was eventuall traced
to configuration of switch one, paddled 5&6. They both have to
be on "no display" for EGA to work. Hope this saves somebody a
bit of time.
