There is an example in the documentation I added. That is using the
Ubuntu 22.04 ISO. Can you give it a try?

You can also try it with a CDROM drive, something like:

qemu-system-x86_64  -drive format=raw,file=root.img -bios
/tmp/b/qemu-x86_64/u-boot.rom -cdrom ubuntu-22.04.2-desktop-amd64.iso
-hdb fat:rw:/home/sglass/cosarm/win/seabios -nographic -m 4096

Regards,
Simon
