That does seem to be the root of the problem. > A main point is the bus-mastering. It is also very important to > performance which device is the master and which is the slave on your > ide-bus. I read somewhere that it really doesn't matter -- it's just an addressing issue.

And I thought that a & b were controller #1, c & d were #2. I'm using the controller(s) on the Intel motherboard. > This is good so far, but you should also enable bus-mastering for you > controller. I googled for IDE bus-mastering. It looks like plain old DMA. Is that all it is? If so, that's done (there's still the 80 core cable issue, but I know about it). > Are there other drives at hdb and hdd ?
