X68000 - Writing 5.25" Floppies in Linux

You need a package of tools called `fdutils` installing, this includes things like 'getfdprm', 'setfdprm', etc:

$ apt-get install fdutils

To set up the drive for the Sharp X68000 track layout, you need to configure the drive. Here's a quick shell script that automates it:

#!/bin/bash

MODE=$1
FD=$2

if [ "$MODE" == "on" ]
then
    echo "1232/1232 2464 16 2 77 0 0x35 0x08 0xDF 0x74" > /etc/fdprm
    setfdprm /dev/$FD -p 1232/1232
    fdformat /dev/$FD
else
    setfdprm /dev/$FD -c
fi

Run it as

$ sudo setx68flop on fd1

Then write your disk image using dd (dd if=image.xdf of=/dev/fd1), finally clear the floppy settings:

$ sudo setx68flop off fd1
