Here's your New Bios, program that file to your 16MB chip and put your 8MB chip back.
Serial Number: MXL6271MVM.

Dear All,

Can I ask some help with my Hp EliteDesk 800 G2 pc?
I have no display, the psu, ram modules and cpu are ok.
2 long, 4 short beeps at startup.
I've attached the original bios I read out with a CH341A

Thank you,

R

You should have another 8MB chip, find it and upload its content here.
Also write your Device Serial Number.

Your file with the name "orig_ec_bios" not good, try to read the chip again.

Re: HP EliteDesk 800 G2 BIOS corrupted by HP bios update

How can I check that the readout was correct? My SO8-CLIPS is a bit worn.

It will be better if you don't use a clip, you need to desolder the chips and solder it back after programming.
Read the 2 Chips again as @hoaca388 said.

Re: HP EliteDesk 800 G2 BIOS corrupted by HP bios update

The attached zip contains the current bios files. I checked them after more readout, they were binary identical.
(In previous reads, AsProgrammer could not read the same binary twice in a row from the same chip, now I use neo programmer)
Unfortunately, I overwrote the main bios a week ago in the belief that I had a correct backup.

Check them please

Serial number (S/N): CZC61194R9

Re: HP EliteDesk 800 G2 BIOS corrupted by HP bios update

Hi,
Thank you.
I've written the new bios and verified it.
-It turns on for 5 secs, turns off for 2 secs and repeats it endlessly.
-No error beeps
-No display
Any idea?
