I've had 2 machines and tried to run Fastback on them. Both (20Mhz 386 and 25Mhz 386) said the DMA was bad and would only run in the slow mode. After being all upset at first, I simply run Fastback in the SLOW dma mode. It takes about a minute to do 1.2M discs (reading or writing). It also doesn't seem to slow at all if you turn on data compression. I use disc caching programs that use the dma channels and they seem to run fine. I think the problem lies in FB's test. Ken
