[LinuxBIOS] Port V1 -> V2

Hello,
How hard is it to port a chipset from version 1 to version 2?
I have a Intel 82830 Northbridge (only V1) and I need to port it to V2.
All the rest of my hardware is already listed in V2.
Can somone point me in the right direction?

Thanks - Joe

Hello,
I wish to carry out the same thing but for the motherboard
advantech/pcm-5823,
he exist in v1 but not in v2, all the chip is already listed in V2 except the
winbond W83977AF.
Can someone point me in the right direction ?

Thanks by advance CCases

If you already have the hardware to test with (bios savior or extra
chips) try creating a target and using winbond w83977tf (ie just tell
linuxbios that's what it is). From a quick look at the source, it
doesn't seem there is anything that should block it from working. Even
if it doesn't work, but everything else works, VGA and USB should still
work, unless a failed superio causes it to hang, but again looking at
the source it doesn't seem it should. You just won't have any serial or
PS/2 ports until you do get it working.

Ok, I think I got it figured out. Attached is my config. Would someone  
mind taking a quick look to see if it looks good?? Feedback?

Thanks - Joe

I don't think your northbridge is going to work. 440bx afaik isn't
working right now, so your quick hack (no offense) to 430 probably isn't
going to work either (although it might). Make sure you've got some sort
of system for getting the factory bios back if it fails (BIOS saviors
are wonderful, if you can get one). Also, when sending things to the
list, it's best if you whip off a patch, as described here:
http://www.linuxbios.org/Development_Guidelines#Creating_Patches, it
really helps to clarify where you've made changes and point out what
you've done. LinuxBIOSv1 also has support for the 430tx, as you've
already noted, and you'll find a lot of info on how things work there,
if you understand assembly. Intel also has some datasheets for both the
430tx and hx, they're all available with a little clicking from here:
http://www.intel.com/support/chipsets/sb/cs-009194.htm

I'm looking at some pictures of the rm4100 (you got me interested in
it), and it doesn't look like there's even a serial port header, let
alone a serial port. Do you have one on your board? That will be pretty
much essential to debugging. As for your TV-Out, initializing it should
be done by the onboard video BIOS, which you'll have to extract and use
with a similar process to the one described here:
http://www.linuxbios.org/FAQ#Testbios_.28vgabios.29_Faq

If you've got any other questions, please post back. I'm certainly no
expert on linuxbios, but I'll try to help if I can, and if not, there
are others around that probably can.

Yes I have a chip programmator. I don't understand if it's possible tu use
the source of v1 en test it directly (on the web for the v1 it are noted
like nonfunctional), or if I must modify the files to function with the v2
?
For me if the VGA, the USB, and the network (rtl8139c) work it's sufficient.

Thank's by advance for your help,

Yes, that should work. Both are very similar and the serial ports
have the same logical device numbers so you should be fine.

I recommend to try v1 first, just to verify that/if it works
there, then you can concentrate on v2.

You cannot use the v1 code as is for v2, though. It must be ported. But
the code is pretty small and porting should be doable.

First you should test whether the super I/O works, i.e. if you get
serial output. That's esential for debugging.

Then you need to get the northbridge (RAM) working, then the southbridge
(for peripheral devices, e.g. network, USB)...

Thanks for the feedback Corey. As far as the tv-out, I don't think  
that is going to be possible to extract it. the rm4100 does not have a  
standard bios. It is a custom designed one for wince and it sucks. If  
you want to check out the project my website is:

http://www.smittys.pointclark.net/rm4100/index.php

There are alot of pics there.
It does have a serial port you just have to use a TTL to Serial  
adapter, just like many cell phones etc. We are in much need of a  
better bios for Linux. That's why I am on a quest for Linuxbios.  
Anyone interested in helping would be greatly appreciated.

Thanks - Joe

ok thank's for your help, I try to test the V1 and I keep you informed,

This would indeed be an interesting project to get working.

Can you send an lspci output to the list, please?

Looking at the pictures, this is a standard PLCC BIOS chip, and it's
socketed, so you can rip it out and replace it with another one
(running LinuxBIOS if you get everything working).

The Super I/O is an SMSC LPCxxxxx (can't read the extact part number
on the picture). Can you please post the part number? This shouldn't be
too hard to get working.
> Anyone interested in helping would be greatly appreciated.

We can help you on the list interactively if you're willing to test
patches etc...

Do you have some spare PLCC chips you can use for LinuxBIOS development?

You already have a running Linux on the box, is this correct?

HTH, Uwe.

[LinuxBIOS] Problem on Compilation in mainboard iei nova4899r

I have test to compil the mainboard iei nova4899r, I have use buildtarguet
for create config file and makefile, but if I tape a make on :

../LinuxBIOSv2/targets/iei/nova4899r/nova4899r/

I have an error :

I don't know why I have this problem. If anyone nows ?
