<font size=3>Hi Stefan,</font>
<br>
<br><font size=3>I think I have verified that there is no issue with flashrom
0.9.3 and the PMC Pm49FL004 chip.</font>
<br>
<br><font size=3>I had received some Pm49FL004 chips from a vendor with
a WinMate I330 BIOS load (an I330 message was being displayed briefly on
BIOS POST). Am I correct in assuming that some portion of the BIOS (e.g.,boot
block) cannot be updated with flashrom? I never saw a checksum error after
rebooting my motherboard and I know that my BIOS defaults had been updated
from the factory defaults.</font>
<br>
<br><font size=3>I have since received some more Pm49FL004 chips from the
same vendor with a WinMate I370 BIOS load and flashing these chips with
a different I370 image works with flashrom-0.9.3 without any issues.</font>
<br>
<br>
<br><font size=3>I apologize for troubling you. Thanks for your help!</font>
<br>

i am not entirely sure, but i think 0.9.3 can not distinguish between<br>
an unknown state and the old, safe state the flash was before flashrom<br>
tried to erase. in your case it would be possible then that the whole<br>
flash chip is write protected and nothing changed/was deleted at all,<br>
which would explain the bootable condition of the system (i.e. you were<br>
lucky).<br>
if that is true we will need to add a small routine that disables the<br>
write protection on that mainboard (if there is no jumper oder bios<br>
option to do so). please send us the output of 'lspci -nn', 'lspci<br>
-nnvvvxxx', 'superiotool -deV' (run all commands as root), thanks.<br>
if not too much of a hassle you should also upgrade flashrom before<br>
further attempts.<br>
