[Request] Bios upgrade of an HP Elitedesk 800 G4 mini to support i7 9700T

[CZanoS]

Hello folks,

I have the HP Elitedesk 800 G4 mini and it is capable of running i5 gen 9 CPUs but not i7 gen 9

Guess it was just not added by HP on its BIOs

Here are 2 bioses.

fw1.bin is for an HP Elitedesk G4 800 Mini that does not support i7 9700T
fw2.bin is for an HP Elitedesk G5 800 Mini that does support that processor

906ED is the Microcode for i7 9700T
It is missing from firmware one, present on firmware two

Is it possible to mod firmware 1 so it is compatible with that CPU?

Attached the one that needs adjustment but there is a 20MB limit so I cannot add the donor fw.

Here is a link to a zip file containing both:

Post a screenshot of Mainboard tab of CPU-Z.
Explain exactly what happens when you try to boot with new CPU.

3 long and 5 short beeps at the moment I power on the machine.

3 long are red on the power led. 5 short are white. (or vice versa, cant remember)
