The "standard" method of getting OpenBSD/pc532 onto your pc532 is
via the console terminal and using the downloading parts of the
ROM monitor.  As such, usually another computer has the distribution
on disk and is connected via a serial line to your pc532's console
port.  A terminal connected to the attached host computer is used
to access the pc532 console via a terminal program.  The source for
a program called download is part of this distribution.  Download
sends data to the ROM monitor over the serial line.

You may need to find and read the documentation about the ROM monitor
download command and other low level commands.

Other methods of getting OpenBSD/pc532 on your pc532 may {:-include-:}
SCSI tape or SCSI floppy disk or cloning a disk on a system
already running OpenBSD/pc532.

If you have some operating system already running on your pc532,
you can use that OS to get OpenBSD/pc532 on a hard disk much easier than
with the ROM monitor.
