Try. it will enter in MPM mode, press F10 and you have a tab under "Main" named " write machine unique data" and you'll find all data on stickers of back of the bottom cover. to exit MPM mode use BCU 4.0 under windows or restart laptop how many times counter shows.Comment

Hey guys,
Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.
Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27
Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit... -
Hi folks,
I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)
Steps I took:- Read BIOS with CH341a, verified hash twice

Hello,
I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).
I have a CH341A programmer and I already attempted the following steps:- Identified the correct chip (W25Q128, 3.3V SPI flash).
- Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: βChip with the contents are in disagreement.β
- Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI
