Hello all,

Is there a problem with the floppy drivers
in FreeBSD? Trying to copy a DOS diskette
using:

dd if=/dev/fd1a of=./whatever

with a disk in the drive got me a most
amusing response.

The machine reported some sort of virtual
memory fault, tried to make a crash dump
and reported a failure, then stuck tight.

Floppy control is from a 1542b, which worked
splendidly under 386bsd-0.1

thanks for reading

bo
