Asking on the LinuxBIOS list is probably the best way, questions and some
answers forwarded there.

Personally I think booting from a local hard driver is a less
manageable way to do things. I have booted a 1000 node cluster over
the network in under a minute.
But there is support for booting from a hard drive.

The DOC has 8MByte of space, yes. I don't use it and I don't see the
need you can load a kernel from other places. And in fact I consider
it a poor choice for any but an embedded user to hard code their
kernel, into the ROM.

Yes. Though I try and keep reflashing down to just BIOS upgrades and
not kernel upgrades.

Talk to the other people on the list. I have provided the answers I
can, but you are coming from an extremely different perspective than
