Mike,

Thanks for this. I have a couple IDE drives sitting around so might try this. 
I had thought the 33MHz mother board host bridge (aka system bus?) was going 
to be the bottle neck on my old PIII board.

Any book suggestions or other resource suggestions where I might read more 
about PCI bus speeds, mother board host bridge speeds, and this kind of 
hardware performance math?

Thanks,

Roger
