Well, however with the origine bios that took a shotgun with the Mazzif tool it was not possible to modify the data or reset give them DMI Tools/AMTool (no memorization by the system) : I was forced to use a different but original raw BIOS…ĮEUPDATE Tool allows you to retrieve the Intel GbE card… The Intel Flash Descriptor is not useful with DMI Tools. When the Intel Flash Descriptor is disabled it is possible to use AMTOOL Brand.bat (Vpro) and delete the commited state on the screen of boot. Mestate tool indicates in (section) ModeOfOperation : Unsecured mode by H/W Jumper When the Intel Flash Decriptor is disabled, the boot screen displays “Asserted Hard GPIO-33”.
On this model it was possible for me to unlock the Intel Flash Descriptor by pressing with holding power + Windows and LeftArrow and Right Arrow (first release bin) : Thank you for your reply, but things have… My positive feedback (and deadly end ?) If anyone has an idea, it will be welcome, thank ! The system is in a bastard state as you will have understood it works but is unusable. I tried a factory reset, nothing to do : despite a reinitiliasitation all diagnostics ok no more boot possible in usb, on hard disk nothing ! Incredible but true I have an alert that the CRC of BIOS is not correct at start-up !Īs a reminder I’m just reading the chip, and as far as I know, nothing else.Īctually the pc doesn’t boot any further, BUT I can access the bios and I can still change the settings. …I decide to stop there and reassemble the machine and start :
I tested an extraction with “CH341A programmer” the chip is detected but the reading impossible…well I dedicate to do a second extraction again the CRC of dump is different and in addition I have the same error ("checking…) Things go wrong when I leave or I decide to patch with ME_Cleaner I get an error:"checking the FTPR RSA signature…INVALID !" So I successfully undertake an extraction of the BIOS with AsProgrammer
So far the system works perfectly and its use is no longer locked, I received a HP in my hands for which I had to use the Mazzif Tool successfully… I am a user of the CH341A programmer with ME_Cleaner for which I have successfully cleaned so far…
