You just need to be able to boot it as a plan 9 terminal connected to a plan 9 file server - then install from that. Can you boot from ethernet (pxe)? Or is there a dos partition on the HDD with room for a plan 9 kernel and plan9.ini? The other possibility is an HDD transplant after using another machine to install onto the drive.
