Here are QEMU images for debian-mips (should be big-endian, as opposed to
Of course it will run purely in software, but most likely more than fast enough
to copy away the data.
Not entirely sure that particular emulated MIPS system support more than 4
drives), but it appears that a starting point could be (man qemu-system):
Instead of -hda, -hdb, -hdc, -hdd, you can use:
qemu-system-i386 -drive file=file,index=0,media=disk
qemu-system-i386 -drive file=file,index=1,media=disk
qemu-system-i386 -drive file=file,index=2,media=disk
qemu-system-i386 -drive file=file,index=3,media=disk
with indexes 0..5, as you need the boot disk, all 4 drives, and one more as
the backup destination.
May or may not be the best way, but IMO beats trying to hex-edit the
superblock right away.
