Re: HP ProDesk 400 G6 Small Form Factor PC bios

Thanks for clarifying, I tried looking for a SOP16 to SOP8 adapter but haven't found one. Also, I'd (if possible) rather use the clip method.
I ordered the kit https://www.amazon.nl/dp/B08HP4X326?...roduct_details and the following clip https://www.amazon.nl/dp/B099X51S1M?...roduct_details

Not sure if this is sufficient?

The Adapter and the board are already within the kit. I don't prefer to use clip because it gives you errors most of the time.

Re: HP ProDesk 400 G6 Small Form Factor PC bios

What exact programmer have any of use used to extract the bios?
I see a lot of SOP 8 PIN tutorials with the CH341A but not a lot of regarding the SOP 16 PIN.

CH341A can handle the SOP16 package, but you need a special adapter that convert from SOP16 to SOP8, search for it and will see.
Also you can solder the chip to the small board that came with the programmer, it has SOP16 footprint and 8 pins.

Here's your Unlocked BIOS, in the first boot go to BIOS Menu and disable security options (Disable).

If the Password still present, see if there is another chip (EC) and upload its content here, it could be 16MB or 32MB.

Thank you

Re: HP ProDesk 400 G6 Small Form Factor PC bios

Hi All, I'm glad I found this thread. I also have a (9AG50AV) prodesk g6 400 mini. It does not have the pswd jumper pins even though there is a pswd area there. My bios is password locked. Reading the replies. Do I need to physically take off the BIOS chip and put It into a circuit chip reader of some sort? Please let me know how to do this. TiA

Hey! Now i get it. Can you help?

Use a programmer to read your bios chip, save the read file in *.bin or *.rom format, unlocking must be done on the locked bios file itself, don't try to post the unzipped file from HP support site it's not a complete bios file.
