editing scripts in linuxbios

[Jim Gettys]

Martin:

You must be *very* careful what tool chain you use for building the BIOS
image.  Right now there are gcc/ld combinations that will produce
unrunable BIOS'es, floating around in different distributions.  I don't
remember the exact versions in which distro's that do work properly.

And therefore, please do BIOS work with the others working on it to
avoid trouble, both for you and us. (e.g. Ron, Richard, Jordan, Marcelo,
etc.).

You should also get a PLCC Flash part (goes in the empty socket) for
your ROM development, rather than relying on the serial ROM on the
board, which if you trash in certain ways, can result in a board that
won't even power up.  Replacing the contents of the serial ROM should
only occur after it has been well tested in PLCC.
                                  Regards,
                                        - Jim Gettys
