Dear flashroom.org  friends.

I am the owner of a HP Compact 8300 Elite Microtower and I tryed to follow the instructions of Paul Murana below,  to modify the BIOS of my PC so that it allows the Start from a NVMe SSD.

Hola, intento implementar esto en un HP Z230 SFF, de momento no lo he probado, solo he encontrado las guías para poder hacerlo. Os adjunto 3 enlaces sobre como instalar NVMe M.2 pcie, reprogramando la bios por software (1 y 2) o, alternativamente, mediante un simple arranque alternativo del bios (3).

All good, but I've got an error in the very last step: flashing the corrected bin file (nvme.bin) .

The error is:
      Error: Unknown chip 'MT25Q128' specified.

The computer remainis ok, but the corrected BIOS could not be flashed. 

Any ideas of what migh have gone wrong?

I previosly updated the BIOS to the version K01 v03 08 and installed a jumper cap into the FDO.

You can find attached the outpot of the terminal log and below the Specs of my PC.

I want to take the chance to give a big thanks to Pauli for his work and sharing his knowledge, and to you for yor kind sppport.

Best Regards,
Manuel dRC
