overriding command line options in LinuxBIOS

[Adam Agnew]

Are there currently any elf loaders that boot under linuxbios which will
let you change the default command line in kernel's made with mkelfImage
from the serial console?

If not, can someone point me to an example of anywhere this works, perhaps
outside of linuxbios? I'd like to add it.

Thanks!

no, but I can try to find my hack which lets you change it interactively 
with the kernel before it is processed.

It was a simple hack.

Even better. I'd love it.

If you do the magic dhcp option dance etherboot should let you append
to the command line.

So the user interface sucks but the code path has been tested.

How about this: define a new ELF boot note which tells the image
to ignore the embedded command line, and modify convert_params.c
in mkelfImage to respect this note.
The new command line can be passed using existing mechanism.
