   The VESA spec says: "Bus mastering on both the VL-Bus or system I/O bus are
fully supported."  What this means to me is that if the motherboard does not
allow bus mastering, its not VESA compatible.  I believe Micronics was on the
VESA committee (along with Zeos) and doubt seriously if they would handicap
their boards like that. IMHO.
