Thanks for the reply, really appreciate it.The idea to suspend to Ram seems
good, it could work probably. I tried to follow a procedure I found on a forum,
that explain how to search for a BIOS LOCK parameter in BIOS binary file and to
use setup_var to change a specific location in memory to unlock BIOS
Write...but unfortunately I was not able yo find that variable in BIOS...At the
end just yesterday I decided to send the PC to the manufacturer for
repair!Thanks again, have a nice day.SimoneInviato dal mio Galaxy

Hi Simone,forwarding your message as it has been filtered due to the
attachment.The mailing list has a limit of 200KiB.This is the most interesting
line out of the picture:> Warning: BIOS region SMM protection is enabled!Well,
this is unfortunate. You may not be completely out of luck,though. Sometimes
the BIOS setup provides options to toggle flashprotection. And sometimes a
simple trick helps to get around it:suspend (to RAM) and resume before you try
to flash. Some BIOSessimply forget to enables the protection during resume.If
you removed the SPI flash from the board anyway, you can alsouse very simple /
cheap SPI programmers without the need of hotswapping. Many SBCs (Raspberry Pi
and the like) can serve asprogrammer, for instance. Or, if you have an old PC
with a legacyparallel port, that can be hooked up to a SPI flash with a
fewresistors.Let us know if you need more infos.Nico-------- Forwarded Message

flashrom@flashrom.orgGood morning, see attached screenshot for the motherboard
ASMB-825.I tried flashrom as I have a bricked motherboard and a good one, and
triedto revive the bad one with the SPI flash hot swap trick, but no
success.Tried flashrom, AFUEFI, AFUDOS, Intel FPT...but none of these are able
toreprogram the damaged flash chip... I'm going to send it to themanufacturer
to have it repaired.Thanks for your help, have a nice day.Simone[image:
