As I mentioned in a previous post I had problems with one of my drives,
which I couldn't set DMA on. Then when I changed memory (the supposedly
PC100 compatible memory I had been sent couldn't cope with 100MHz bus) the
problem disappeared. I have no idea why, it's just a bit bizarre. Voodoo
magic probably :)
