Hello,

This is due to the FREGx and FRAP flash-region access and permission
registers above.  Since your BIOS doesn't lock these registers, I've
attached a patch that will modify FRAP to allow reads and writes.
Please note that there may be other things that will prevent reads or
writes from working.  Either way, please reply with another `flashrom
-V' (or -Vr, -Vw, ...).

Thanks,

Josh
