Hmmm, I have a similar problem but figured it was something I'd done.
I have Buslogic 445C VLB controller, an IDE VLB controller, and an
ATI VLB GUP graphics cards (3 VLB slots), running under Linux 1.2.10.
I haven't tried much with the floppy, but ftape (2.03b) isn't working
correctly - tapes are sometimes not recognized, and when trying to
do a backup, ftape begins to lose track of where it is on the tape
after a few minutes and starts performing long seeks across the tape.
This is with the floppy and floppy tape attached to the IDE card. I
figured I would try it attached to the Buslogic card next.
Nothing in the 445C docs said it needed a bus-mastering VLB slot - how
do I tell if my MB has one, and which one slot it might be?
Thanks!
