Hi,
at first I want to thank everybody working on flashrom and coreboot. I really appreciate your work.
I have ASUS Sabertooth 990FX R2.0 motherboard and I got message: "This flash part has status UNTESTED for operations: ERASE WRITE"
Because I have also a spare chip, I tested this operations with the original one and it seems working - my computer is able to boot after erasing the chip and writing the ROM image :-) Original chip is Eon "EN25F64" (8192 kB, SPI). For more details please see attached files.
