Ok, the problem is that using busmaster DMA on my hard drive is not stable. OSR2/Win98 check box or VIA busmaster drivers do not work. The system always locks up while running defrag, or when unRARing certain archives.
Now, does the HDD use DMA channel 3 for busmastering? If so, it's already in use by my ECP printer port. Or am I way off base here. Anyone who can help me get busmastering running on my system will get a 500 point bonus when I have completed stability tests.
Board is a Matsonic MS-5120 VxPro+ (VIA VPX ripoff).
