I tried it this morning and it worked fine ftp'ing about 80 Meg of files
across a 10baseT network (without Alan's fix). Also as I mentioned in my
previous message, I can copy from an IDE drive on the system fine, but not the
IDE CD. I wish I had another CD-ROM drive to try but I don't my other one
went bad a while back. If it's a timing problem I guess it's plausible that
both the net and the CD on your machine could trigger it, while only the CD
does so on mine (so far), but I'm no expert by a long shot.

Thanks for your reply!
