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 The next thing to do is Code:
$man fdc 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 And I do a disk check: Code:
#fsck -p /dev/fd0Bi /dev/fd0Bi: 14 files, 194 free (389 clusters) 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

I'm wondering where on earth you get floppies these days.
Do you still have leftover AOHell floppies? |

hermano, yes, one can still obtain this media.
