Hi,



My LiteOn DVD burner fails (reading) when put into DMA mode (and runs real slow if I run in PIO mode). Any possiblility of reprogramming the



8237 (style) DMA controller for a wait state or two? Or any other suggestions?

I've had a PC slowly corrupt a hard drive from being set to 66/100 -- this was in the early days of such drives/motherboard combos, though, so I can't complain _too_ much. (I'd have felt far worse with the early motherboard with USB that that silicon bugs that simply couldn't be worked around in software -- at least with the hard drives, DMA33 worked and was still faster than the drive could transfer data anyway...)

Bonnzzzaaaaaiiiii!!!

Changing the IDE drive cable BIOS setting from 66/100 to 33 (Mhz?) totally fixes the problem.
