I'm a UNIX savy, but a zip drive novice. After some Howtos, and some
trys, my zip drive seems to be working very well. Well, almost. While
I'm copying large files to it, the performance of my X windows goes

I thought it could be a BIOS problem, as in the HOWTO, it is said to
choose one of "standard" or "bi-directional". The options I have are:

Compatible (the common sense tells me this is standard)
ECP (I have to choose a DMA & version in this)

And I use "Compatible". Is there a better thing to do? Is this bad
performance "normal"?
