[LinuxBIOS] My first attempt at linuxbios

[Jon Dufresne]

Hello,

I am creating an embedded system. Right now I am investigating
different custom bioses and am seriously considering LinuxBIOS. Let me
give you a rundown of the hardware I am using

CPU: Pentium M
Mainboard: Custom board based on BCM GT855
Northbridge: Intel 855GME
Southbridge: Intel 82801DB
SuperIO: ITE IT8712-F

In the source tree it looks like there is some level of soupport for
all these devices except the mainboard. I am going to attempt to
create a mainboard and target to get this setup working. One thing I
want to do is build a minimal target and then implement the features
incrementally. With this is mind, do I need to create any source code
for the initial run or is the entire build defined by the Config.lb
and Options.lb? I've read through all the documentation I could find
on th website so I think I have a decent idea about how the LinuxBIOS
system works. I believe my payload will be FILO. In the end my system
will be booting RHEL. I'm willing to put a lot of work into this, but
I want to see what others thought about compatibility with this
hardware setup.

While I'm here, what is the difference between the Config.lb and the
Options.lb file. They both look like they set configuations/optoins,
but I am not sure what options/configuations go in which file.

Thanks for the great soft/firmware and thanks for any feedback.

-Jon
