Comment out several lines about links in resourcemap.c.


Current inherent_ht.c already could probe the links automatically...


amd/Serengeti_leopard is good model. If you want mptable and irqtable
and acpitable create automatically.

Hello LinuxBios elders,


I'm sorry to bother you.


I'm begining to study LinuxBios and I have some problem in it.

Hope you can give me some idea.


My target board is an AMD Opteron (chipset: K8 / 8111 / 8131) mainboard,

it is similar to Tyan s2880 / s2881 / s2882.


So I base on Tyan s2880 to change some config file to compile a

but it doesn't work.


Following is what do I changed in s2880:

1. I changed the payload path in targets/tyan/s2880/Config.lb.

2. modify src/mainboard/tyan/s2880/Config.lb as 42812-pci.txt. ( as
attachment )

    I don't know is it correct that I modified. If you have interest you
can refer to Attachment.

3. generated irq_tables.c by getpir.c and replaced the original one.


compile and burn it in rom.


After I boot up the target board, it always alert emergency beep.


Then, I unmark some debug message in
'src/northbridge/amd/amdk8/raminit.c' to see where is it hang.

The last step is hang on setup_default_resource_map() in

I can see it from serial console ( as attachment again. ) 


Is there any configuration I should change, and I didn't do ?

How can I debug it ?


Thanks a lot.

Vincente Tsou
