Compaq Armada M300 Repairs

I have aquired a Compaq Armada M300 that has no OS on the hdd. I’m trying to install one, but there is no floppy and no cd with this particular little beastie. USB support is non-existant, as is network connectivity, as it doesn’t have the software to support it and the BIOS is older than dirt. Anyone know what I might be able to do, other than purchasing a seriel floppy and praying that it will work?

Any ideas would be great. Thanks.
