How are your hacking skills?

LinuxBIOS V1:
Supports the 440BX but it dosen't know anything about SMP or AGP and
you would probally need ADLO to make the video bios work.
By 309 I'm guessing that the pc87309 superIO?  V1 seems to have really
basic support for enableing that on boot but the comments say its
specific to a particular mainbord.  So some work is needed there as

LinuxBIOS V2
I have a set of patches vs an old version of V2 that add the framework
for 440BX and was enough to make our product come up and say stuff out
of the serial port. (pc87351)  However I got stopped trying to read
the RAM info via the SMbus.  For some reason I always got back zeros
(or FF's I dont' remember).  Unfortunatly that product never made it
beyond prototype and so I didn't continue to try and transition from
V1 to V2.

If you are interested in working on it I can fixup my patches against
the latest SVN tree and submit them.  There's a lot of coding work
that still needs to be done after that though.

I have somewhat of an interest in this as I have a Dual P3 machine
with a 440 chipset on it that can't use newer larger hardrives because
the BIOS chokes and I also have some of the prototypes from our
product that could be used for something.  I just don't have a lot of
time to allocate to this.  But I could test things in the evenings and

It would be really nice to have full V2 support for the 440 family. 
There are tons of old cheap mainboards with these chips on them and
would be great for hobbiest or personal type stuff.
