- 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.
