Unfortunately, not even Borland can figure out a way to autodetect the 6300
display.  I asked them the same question last month.  One way to do it
(a real kludge -- but it should work is to look for the copyright notice from
AT&T &/or Olivetti in the Bios Roms).  I may try to do this myself in the future
but I haven't tried it yet.

Before complaining about the problem -- the reason we've got the autodetect
difficulty is the extremely good cga emulation that Olivetti designed into the
M24/M25 machines.  Everything I've tried on the video installs for a CGA and
runs beautifully -- so I guess we should be glad for the small problem. :->
