I wonder how hard it would be to copy this with old PC boards. Given how non-standard PC hardware is, I guess you'd have to know what motherboard you've got before you can start trying to mod it to network boot.
It looks like Coreboot doesn't support any boards older than the Pentium II timeframe.
I figured I'd be dredging up hardware old enough to not support PXE. If it's possible to add a PXE NIC and boot off the network without a PXE-enabled BIOS, that is both news to me and very cool.
