Enquries on how to map the bios chip into address space
by mtech se13b 26 Sep '09

26 Sep '09

Dear all, I'm currently actually trying to access the content of the bios chip while the bios is doing its execution. I'm working on Intel Q35 chipset. And i understand that while the bios is executing, i can actually access the TOP 2MB of the 4 GB address space to access the bios chip raw data content. However, my bios chip is actually 4MB in size, can someone advice how do i go about accessing the other 2MB of the bios chip while the bios is executing? Because not much documentation on this and i hope someone in the coreboot community could help me on this. Thank you very much. Rgds. Stanne.

Dear coreboot readers! This is the automatic build system of coreboot. The developer "stepan" checked in revision 4680 to the coreboot repository. This caused the following changes: Change Log: This patch changes following in getpir application. 1 - Moved the check sum validation to probe_table function. 2 - Proper handling of resources allocated. 3 - Signature check is done in 16 byte boundaries. 4 - irq_tables.c file is created only if a valid PIRQ table is found. 5 – Makefile and README file are modified accordingly.

Dear coreboot readers! This is the automatic build system of coreboot. The developer "stepan" checked in revision 4679 to the coreboot repository.

If this issue is not fixed within 24h the revision should be backed out. Best regards, coreboot automatic build system
