Hello all, Recently purchased new motherboard (ECS 755-a2). Installed, no probs there. Running XP Home. For the life of me can't get DMA enabled on primary channel. In BIOS, when I enable IDE DMA transfer access, computer acts like it can't find OS. When off computer runs, albeit in PIO mode for HD. ECS 755-a2 mainboard (SIS 755 chipset) 160gb seagate HD HP DVDR/W drive 512mb pc3200 DDR GF Fx5200 128mb GPU Athlon64 3200+ processor Really ticking me off, PIO is slow as snail snot! Thanks for the help!
