[REQUEST] Fujitsu Lifebook E544 Whitelist Removal
#1
Model: Fujitsu Lifebook E544 https://www.fujitsu.com/hk/products/comp...ries/e544/
BIOS: Phoenix Technologies
Similar topic: https://www.bios-mods.com/forum/showthre...?tid=27352
Actually, i have used UEFItool, and found C13AE648-252D-488E-923E-739D55367C3B_888 module (WwanDxe.efi).
In disassembly (with IDA Pro) of this module, it seems a right action, to make function sub_B28 to not perform __outdword(a1, a2);
I have modified bios file, and tried to write it to flash using fptbios

And i see:
Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.
Please Contact the target system BIOS vendor for as option to disable Protected Range Registers

help to understand what is this error, how to overcome it.
