[LinuxBIOS] Linux kernel for LinuxBIOS?

[lihao]

Hi all,

I know if i want to use linux kernel as payload to LinuxBIOS, I must
edit the source of Linux source code. I want some more detailed
information, such as:

1) what version of Linux? 2.4 or 2.6
2) how to make it tiny? less that 512KB? less than 256KB?
3) what to edit? Is there useable patches?

I know Erik Andersen's buildrom maybe help, but when i type "make all" I
cannot compile the code successfully. By the way, some source code from
net is unaccessable. Don't know why.

Regards,
Hao Li
