w/re the Nugent posting on detecting AT&T 640x400 by trying to set an AT&T
specific graphics mode and assuming that a rc of 0 implies that said mode is
supported - fails in too many cases...  i've learned the hard way, having been
the pc graphics support person here at SLAC for the last several years - there
are too many vendor specific BIOSs out there that when confused return a 0 rc -
the safest way i've found is to look at the BIOS copyright - see my posting of
last week.
