Does IDE DMA work? I use the CD-ROM on the onboard IDE port so that I have DOS access and when in Windows, I don't recall if there is the DMA check box option under the CD-ROM. I thought not, but I'll have to check.
EDIT: What happens when you put a check mark in DMA for the CD-ROM then reboot? Think back now, I recall doing this, rebooting, but the DMA check box disappeared. What date do your IDE drivers have? Mine 6-30-2001. I'm not sure where they are from.

The latest update for this board, which is a package called updtpi31.exe, Revision 3.1 - 8 April 1996, doesn't have any mention of IDE DMA drivers. It provides the DTC branded EZIDE.EXE for Windows 3.1 only, so I assume we are left to rely on Windows 95 for drivers. WIN4BM.386 is the DMA IDE driver for Windows 3.1x, but if you read v3.1 notes, it says "*** NOTE!! *** Do not use these drivers with Windows 95."
The previous revision update utility, v3.0, contained a DTC benchmark utility, DTCSPEED.EXE. Have you played with this and determined if DMA is working?
