thats what i thought. been looking for second chip.
hence i double inspected board, but found nothing what may looks like bios chip.
No schematic or boardview, any idea which chip it is?

(obviously will check it again by myself) but any help welcome

You are very confused and probably using crappy ch341 programmer.

The screenshot is a TL866 programmer software. The 1MB chip is firmware for something.

Keep looking for another chip,it might be a WSON8 type, with no legs.Post your backup once youve found it,your backup will have your DMI info,it can be copied to a new bios easily with a hex editor,it will save having to use HP`s crappy DMI tools.

This is his screenshot, he found the chip already.

The old TL866A and CS have no support for it but the TL866II does.

That's why I use RT809H, never failed or confused me, and has continuous support for many new chips. I ditched the old TL866 because of this time wasting crap.
