I've had a silly problem a few days ago (couldn't patch the 851 firmware because writing to the file was disabled). But now I can't apply the 851 firmware (GS0C) at my 451 as it says "Unable to write firmware. Please contact with your vendor."
Don't know what it is but the patched firmware only lists up the IDE channels when I should select a drive and not explicitely a 451 drive.
Does someone know?
