First, you'll need a boot floppy.  Making one of those is not something
I want to go into in detail right now, I'm afraid.  It's not always
trivial.  You might want to look at picobsd for inspiration.

Once you've done that, you'll want the mkisofs port.  There should be an
option in there to create a .iso file with an "El Torrito" boot image.
The image is the boot floppy, copied into a file with dd.

When you have your .iso file, you can write it to CD using the cdrecord
port if it's a SCSI cd burner, or the native burncd(8) command if it's
an ATAPI cd burner.

Not trivial, but doable.
