I am getting errors in accessing fd0.  I can boot a FreeBSD floppy.
DOS has no problem with the device.

I never see or hear FreeBSD access the device.

I am running FreeBSD 3.0-CURRENT #0: Fri Jun 19 09:15:17 PDT 1998

The only IDE storage device is the floppy.  There are 3 SCSI disks and
a SCSI CD.  The SCSI controller is a NCR PCI device.

>From dmesg:
fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa
fdc0: FIFO enabled, 8 bytes threshold
fd0: 1.44MB 3.5in
fd0: 1.44MB 3.5in

With a floppy disk I can mount on another system, I get:
# mount /dev/fd0a /mnt
/dev/fd0 on /mnt: Input/output error
and, dmesg has:
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0c: hard error reading fsbn 16 of 16-31 (No status)
The LED on the drive does not light, and, drive is not accessed, the
heads are not heard to move.

With NO floppy in the drive,
# mount /dev/fd0a /mnt
/dev/fd0a on /mnt: Input/output error
and, dmesg has:
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0c: hard error reading fsbn 16 of 16-31 (No status)
The LED on the drive does not light, and, drive is not accessed, the
heads are not heard to move.


Is there a problem with the fd driver?  Is there an updated driver?

I have:

sys/i386/conf/<kernel>
controller      fdc0    at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr
