[LinuxBIOS] linuxbios on commel lv671 board with ICH4 chipset ?

[Dieter Bloms]

Hi,

I own a commell lv-671 board and want to install a linuxbios, because of
supporting serial console.

I successfully made a qemu bios and it works as aspected

From the source I see, that the i82801db and i855pm is supported.
Is the i855pm compatible to i855GME ?

Or does anybody have successfully build a bios for the lv-671 board ?

PS.: Here is a link to the board:

Thank you in advance

Hello Dieter,
As far as the i855pm compatible to i855GME, should be compatable.  
Intel likes to add letters on to the end of the chipsets for slight  
variations in the same chipset. As far as the southbridge, the  
i82801db src has some bugs, first the src refers to it as an ICH5 when  
it is an ICH4 chip (just text errors), also the PCI ID devices are not  
defined in pci_ids.h or they should just be hardcoded into the src  
drectly, and lastly it does not offer ethernet support. I have fixed  
all these bugs but have not submitted a patch yet because I have not  
been able to test it.

Thanks - Joe

lspci give me lines like this, so I think it is compatible:

00:00.1 System peripheral: Intel Corporation 82852/82855 GM/GME/PM/GMV

that sounds good to me, ethernet support is not needed for me to boot,
I only want to boot from harddisk or cdrom.

I was told, that there were some kind of hardware sold, so I can savely
flash my bios and restore to the old, if it fails.
Does anybody know a link to such hardware ?

I want to buy it and then I'm willing to test your patches.

Hello,
Your looking for a "bios savior" depending on what kind of package  
your bios chip is (PLCC32 possibly). Also make sure the bios savior  
you get supports a firmware hub (FWH), I am sure that is probibly what  
you have (most intel boards have firmware hubs).

Thanks - Joe

It should be, but according to Ron, the i855 was never supported and
working. It was checked in but it would not survive ram init. Has anyone
gotten further than this on an 855?

Someone might be able to do so. Just send it to the list.
