I have a 32-bit machine running OpenBSD 6.0.

The first thing to do is look at the dmesg for fd devices:
Code:
#grep fd /var/run/dmesg.boot
fdc0 at isa0 port 0x3f0/6 irq 6 drq 2
fd0 at fdc0 drive 0: 1.44MB 80 cyl, 2 head, 18 sec
fd1 at fdc0 drive 1: 1.2MB 80 cyl, 2 head, 15 sec
Floppy devices are defined/configured in the BIOS on traditional Intel style 32-bit machines.

The next thing to do is
Code:
$man fdc
Since I have a 1.44MB 80 cyl floppy, my device is /dev/fd0B

Trying to figure out the partition to mount, I do:
Code:
 #disklabel fd0B
# /dev/rfd0Bc:
type: floppy
disk: floppy disk
label: fictitious
duid: 0000000000000000
flags:
bytes/sector: 512
sectors/track: 15
tracks/cylinder: 2
sectors/cylinder: 30
cylinders: 96
total sectors: 2880
boundstart: 0
boundend: 2880
drivedata: 0 

16 partitions:
#                size           offset  fstype [fsize bsize  cpg]
  c:             2880                0  unused                   
  i:             2880                0   MSDOS
So partition "i" is the one I want.

And I do a disk check:
Code:
#fsck -p /dev/fd0Bi
/dev/fd0Bi: 14 files, 194 free (389 clusters)
And mount the drive:
Code:
#mount /dev/fd0Bi /mnt 
#df /mnt
Filesystem  512-blocks      Used     Avail Capacity  Mounted on
/dev/fd0Bi        2847      2458       389    86%    /mnt
#mount
/dev/wd0a on / type ffs (local, noatime)
/dev/fd0Bi on /mnt type msdos (local)

I just want to be clear, the machine that I am writing to the floppy with is 64-bit and the computer that I'm trying to get to read it is 32-bit. The image is 32-bit of course.

Also, none of the /dev/fd0{A/B-H} devices exist and an error states that they are an unknown special file or file system. Is this because it is using the default and omitting the letter? Either way when I try to mount with #mount /dev/fd0c /mnt/floppy I get an input/output error and I also get more input/output errors when I try to mformat.

As I said "Floppy devices are defined/configured in the BIOS on traditional Intel style 32-bit machines."

Is the BIOS configured for a 1.44M floppy drive?

If not, then when installing/starting OpenBSD, the floppy drive will not be seen.

To fix this, modify the BIOS to configure a 1.44 floppy drive and then run MAKEDEV in OpenBSD to create new /dev/fd* devices.

After the floppy is configured in the BIOS it should also show up in the OpenBSD dmesg.
Code:
#grep fd /var/run/dmesg.boot
or
#dmesg |grep fd

Could you please copy/paste your dmesg here ?

I'm wondering where on earth you get floppies these days.

Do you still have leftover AOHell floppies?
