Does PCI bus mastering matter in Dos or offer any speed improvement (SVGA games). Using a SE440BX-2 motherboard that has PCI bus master slots I tested a few cards.
1999 Vodoo 3 3000 PCI - no bus mastering
1996 DIamond Steath 64 VIDEO VRAM PCI - no bus mastering
1994 Mach 64 PCI - supports bus mastering
1993 Mach 32 PCI - supports bus mastering
Also tested some promise PCI ide controllers just to check and they all enable bus mastering.
This was in DOS 7.1 using various utilities like NSSI that show PCI slot information. Surprised me the older cards enable it in dos but not the newer cards.
