I download a lateset snapshot from linuxBIOS.org yesterday. I don't know if it is bad luck or something, I can not successfully build any BIOS from the tree I downloaded. I tried following three platform.

I get a error output like below: (Note: Changing options in the Options.lb above were not the cuase of the problem. Without changing USE_DCACHE_RAM and CONFIG_USE_INIT, I still get same results)

gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /export/1/new/src/config/linuxbios_ram.ld linuxbios_ram.o
linuxbios_ram.o(.text+0x13db9): In function `smp_write_config_table':

2. amd/serenade gets the build error like below. It probably is the side product of the tree enabled dual core and cache as RAM?
