The contents of the <code>qcow2</code> file can be extracted and copied into hard drives for bare metal BIOS/Legacy CSM booting.

To extract the contents of the <code>qcow2</code> file, decompress it first and convert it into <code>raw</code> format.

$ xz -d maemo-leste-1.0-amd64-virtual-20180425.qcow2.xz
$ qemu-img convert -f qcow2 -O raw maemo-leste-1.0-amd64-virtual-20180425.qcow2 maemo-leste-1.0-amd64-virtual-20180425.raw

The raw image that it yields, can then be setup as a loopback device, and its partitions mounted.

# losetup --partscan -f maemo-leste-1.0-amd64-virtual-20180425.raw
# mkdir /mnt/maemo-virt
# mount /dev/loop0p1 /mnt/maemo-virt

Setup one <code>Linux</code> partition on the device to be used for booting, format it with a GRUB-compatible filesystem (<i>ext4</i>, for example), then mount it as well.

# cfdisk /dev/sdb
# ...
# mkfs.ext4 /dev/sdb1
# mkdir /mnt/maemo-bare
# mount /dev/sdb1 /mnt/maemo-bare

Change directory to the loop partition, the copy over its contents into the bare metal partition.

# cd /mnt/maemo-virt
# rsync -aAHXv * /mnt/maemo-bare

Once finished copying, bind mount special filesystems into the bare metal Maemo partition, then change root.

# mount --bind /dev /mnt/maemo-bare/dev
# mount --bind /proc /mnt/maemo-bare/proc
# mount --bind /sys /mnt/maemo-bare/sys
# chroot /mnt/maemo-bare /bin/bash

Load the new root's shell profile, install GRUB to the bare metal boot device (<i>/dev/sdb</i>, in this example), then regenerate the GRUB configuration file.

# . /etc/profile
# grub-install /dev/sdb
# grub-mkconfig -o /boot/grub/grub.cfg

After that, you may exit the chroot environment (Ctrl+D), unmount all the filesystems, then reboot the system into your new bare metal Maemo Leste installation.

# umount /mnt/maemo-virt
# umount -AR /mnt/maemo-bare
# reboot
