[coreboot] Advice on how to approach porting old hardware?

[Shane Norris]

Thanks to all that replied, so looks like ill be starting with v1.
Hopefully I can find an archived live-cd from around that time with a
tool chain all ready to go. Longer term I plan to get v4 going since I
will still need to support these things once there running.
