[LinuxBIOS] Need help with northbridge section of Config.lb

[Jon Dufresne]

Hello,

I am currently trying to configure my Config.lb of the mainboard
section to work with my board. I modeled my file after the
digitallogic/adl855pc since it uses the same north/southbridge as my
board. I am having trouble finding complete documenatation about how
to write this section of the config, perhaps if I get this working I'd
be willing to create some to help others.

So I was wondering if anyone with more experience than I could look
over what I have so far and let me know if I'm on the right track, or
way off. I'm really not sure what to put where. I'm most confused
about when to put lines between "on" and "end" and when not to. What
to put under the southbridge, and what not to, things like that. I'll
also attach my lspci to give you some idea about what my hardware is.
I am also really confused about where to get the values that appear
under the superio, should I look in my superio datasheet for those?
Also in the example I started with I saw lots of "register" lines in
the file. Can someone give me an idea what these lines do exactly?

Thanks for any help!

Here is what I have so far

Think of the "device" as an implicit {. On is an attribute: you are
turning it on. End ends the block as a {.

So we could have done this:
device(pci, 0, 0x1d, 0, on){irq=0x4d;}

but we did not think of it.

We should have had a better syntax. My bad. This is all going to
change for the better in v3.

Look at LinuxBIOS-AMD64.tex in svn, I think that documents most of the
syntax.

I've read through this document but still am not sure what these
keywords mean. If I screw up in this section of the code, will my bios
be useless? I'm thinking I should spend more time getting this part
right before moving to other parts of the code. What do you think?

Basically my bios does not give me any feedback, through serial or
anything. Is it possible the error is here?

Thanks,
Jon

You need to get the SuperIO part right and make sure your
DEFAULT_LOG_LEVEL is high enough (8 or so)
