5.25" Floppy disk drive not recognized

[Christoph Kukulies]

First problem was to recognize the 5.25“ drive from the BIOS.
This MB seems to only support one floppydrive. It comes with an ASUS branded point to point cable (one connector only).

At least I managed that FBSD now recognizes the drive:

fdc0: <floppy drive controller (FDE)> port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on acpi0
fd0: <1200-KB 5.25" drive> on fdc0 drive 0

But when I’m trying to
d# dd if=/dev/fd0 of=fd_dump 
dd: /dev/fd0: Device not configured
0+0 records in
0+0 records out
0 bytes transferred in 0.000252 secs (0 bytes/sec)
# 


Do I have to specify  special blocksize?
