I noticed that the erase fails on the SST25VF016B. Attached is the log file for burning a portion of the bios file.
Thanks for your mail. While the output of flashrom is quite unclear, what you are observing is not an erase failure, but normal operation on Intel chipsets. Intel Chipsets allow only to send 8 predefined commands to the flash chip and flashrom does not yet support changing the predefinitions on the fly.
Your flash chip supports different erase commands (mostly eraseing different block sizes), and both 0x20 and 0x52, the first two erase commands listed for your chip, are not in the default list-of-eight that is sent to the chipset, so these erase methods fail. The third one OTOH worked flawlessly, allowing flashrom to continue.
