How to Combine intel ME + BIOS to one spi fash file ?

I have succeeded to recover my hp laptop with the help of this forum, only one thing I can not sort out.
How to make a fresh / brand new bios file ?
In may case the hp site offers me only the uefi bios but is is missing the intel ME to make it complete, I had the luck my bios supplier sent the file but how to make one self

I could not find a how to for it.

thanks

The general idea is explained here. In more detail, the SPI chip consists of regions: Flash Descriptor, GbE (optional), ME and BIOS. You only have BIOS (from HP) so you need to find/recreate FD and ME. For these, you can either dump your current SPI chip or find another system’s dump online (if yours is corrupt, wiped out etc). Now that you have a SPI dump with FD & ME, follow the ME cleanup guide. Once that’s done, you have a SPI image with FD + ME (cleaned/configured) + BIOS (dirty/not your own). Open that image with UEFITool and replace the BIOS region with the one from HP or your own. So now you have a SPI image with FD + ME (cleaned/configured) + BIOS (HP, your own). That’s all.
