Today I was trying Coreboot, but I made some mistake and bricked my Asus  
A8NE-FM board. Fortunately I had another board P5PE-VM with similar ROM chip.
I booted it and then replaced the ROMs and wanted to flash the A8NE-FM's one 
with the original BIOS. But I get an error:

Found chipset "Intel ICH5/ICH5R", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Calibrating delay loop... OK.
Found chip "PMC Pm49FL004" (512 KB, LPC,FWH) at physical address 0xfff80000.
Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... Programming page: ERASE FAILED at 0x00000000! 
Expected=0xff, Read=0x4c, failed byte count from 0x00000000-0x0000ffff: 0xfed3
Your flash chip is in an unknown state.

I checked if there is any write protection in BIOS settings and didn't find 
any. But people at IRC chanell, especially twice11, helped me. After some 
diagnostics he send me a patch which adds writing capability for P5PE-VM 
boards. So I was able to flash the ROM and put it back to the A8NE-FM.

Thanks a lot for that! I think, free software has much better support and 
works more effectively – if it were an commercial closed source product, It 
would take several days or weeks and may be never be supported... So thank for 
your work :-)
