One note about the board testing Wiki page you may want to clarify:
"To check if you can read the existing BIOS image from the chip, run flashrom -r backup.bin. Make sure that backup.bin contains a useful BIOS image. (Some chipsets will return 0xff for large areas of flash without any error messages.)"
For a BIOS newbie like me, the remark in parenthesis doesn't tell much - is it a good or a bad sign if a chipset returns 0xff for large areas of flash without any error messages? (Bad, I guess ;))
While booted with factory BIOS, make note of the BIOS version you currently have. Compare the backup image with a copy downloaded from ASUS. If they are mostly the same with only configuration store areas differing, you should be fine.

By the way, what is the status of ASUS P2B-LS support? I reported here earlier that the same support mechanisms for P2B-F also work for the LS. And I have successfully flashed multiple times on a SST 39SF020 chip.
Thanks Keith
