HP laptop BIOS - add new CPU microcode

[4r0]

BIOS link: https://ftp.hp.com/pub/softpaq/sp55001-5...p55068.exe
What happens: I want to insert a new CPU microcode update into the BIOS.
CPU spec: SR02Y I guess

CPUID Manufacturer: GenuineIntel
CPUID Revision: 000206A7h
Microcode Update Revision: 1Ah

The latest microcode (Intel, all of them): https://downloadcenter.intel.com/downloa...duct=52219
The latest microcode (github, I guess it's the latest for my CPU): https://github.com/platomav/CPUMicrocode...6F65DE.bin

I decrypted and modified it following the https://web.archive.org/web/201410160356...codes.html manual, but of course I can not flash it, because I need it to be signed.

After modding BIOS you must encrypt it (by hewprsa.exe) and use patched iscflash.dll to flash.
This dll-file can be extracted from Camiloml's mod.
