Installing Linux

Download a m68k distribution, such as debian-10.0-m68k-NETINST-1.iso. Create a hard disk image to install onto.

Extract the installation kernel and initrd from the installation CD:

 guestfish --add debian-10.0-m68k-NETINST-1.iso --ro --mount /dev/sda:/
 <fs> copy-out /install/cdrom/initrd.gz .
 <fs> copy-out /install/kernels/vmlinux-4.16.0-1-m68k .

Boot from the CD image:

 ./qemu-system-m68k -boot d \
 -M q800 -serial none -serial mon:stdio -m 1000M \
 -net nic,model=dp83932 -net user \
 -append "console=ttyS0 vga=off" \
 -kernel vmlinux-4.16.0-1-m68k \
 -initrd initrd.gz \
 -drive file=m68k-deb10.qcow2,format=qcow2 \
 -drive file=debian-10.0-m68k-NETINST-1.iso,format=raw,media=cdrom \
 -nographic

Use the following for the source for network-based installation:

 http://ftp.ports.debian.org
 /debian-ports/

After installation, extract the kernel and initrd from the hard disk image;

 guestfish --add m68k-deb10.qcow2 --mount /dev/sda2:/
 <fs>copy-out /boot/vmlinux-4.16.0-1-m68k .
 <fs>copy-out /boot/initrd.img-4.16.0-1-m68k .

To boot from the HD image, you can use:

 ./qemu-system-m68k -boot c \
 -M q800 -serial none -serial mon:stdio -m 1000M \
 -net nic,model=dp83932 -net user \
 -append "root=/dev/sda2 rw console=ttyS0 console=tty \
 -kernel vmlinux-4.16.0-1-m68k \
 -initrd initrd.img-4.16.0-1-m68k \
 -drive file=m68k-deb10.qcow2,format=qcow2 \
