Hello,
I like to play with an ASUS P3B-F lingering around. Neither the original (M29F002) nor an replacement Flashchip (39SF020A) is recognized. According the documentation this should be supported. The flashrom from flashrom-0-0.5.20071118svn2967.fc8.i386.rpm provides this output:
Calibrating delay loop... OK. No LinuxBIOS table found. Found chipset "PIIX4/PIIX4E/PIIX4M", enabling flash write... OK. No EEPROM/flash device found.
A recompile from LinuxBIOSv2-2994.tar.bz2 reveals the same. The result of probe_jedec seems flaky.
Either I do something wrong or there is a bug. Is there any advise how to resolve this?

Cool!

The mainboard probably needs some extra tricks to let the write enable signal through to the flash chip. It is needed also to identify the flash chip. :\
Some Asus boards had a tricky SMBus mux thing going on. Maybe that is what's causing problems here too?
