[Q] Replacing HP Elitedesk 800 G4's BIOS with a 800 G5 BIOS with a flahser to support 9th gen CPU, feasible?
Hey there, i just got this 800 G4 SFF pc, i have seen people boot off i5 9500 with a Elitedesk 800 G4 DM so i figured "Well, then this 800 G4 SFF _might_ work with my i7 9700", i tried booting with it and it would come back with 3 Long 5 Short beep ('CPU Initialization error' according to Beep Diagnostic PDF) after that i tried updating it to the lastest firmware and it still wouldnt boot and thats when i realized i needed the 800 G5 instead, but sadly in my area there's almost noone selling a 800 G5 at cheap, which i really need since it has the intel ethernet and Intel ME which would come in clutch to use as a homeserver as my previous machine had a Realtek ethernet and it had alot of trouble with my linux kernel
So i went online to check whats really the difference between the Elitedesk 800 G4 SFF and Elitedesk 800 G5 SFF motherboard but i cant see any difference, atleast visually, even from what i heard they had the same chipset?... i was wondering if i can just take a backup of my current flash (the 16+32mb) with a CH341a flasher, flash the 800 G5 bios into it and call it a day?
