Hello,

Please forgive me if I'm not doing this request correctly, I was unsure from the rules if I should add this request to an existing thread with the same title or if I should create a new thread.

I have a few goals here.

In the short term I would like to enable NVME booting in UEFI mode on my old Dell T7600 system. I have capture the BIOS (from the U_SPI1 / U_BIOS1 IC) with a SPI flash programmer and attached it here [[File:bios-dell-t7600.zip]] . If someone was able to modify this BIOS to add the NVME support, that would be helpful.

Longer term, I would like to understand more about how people do UEFI and BIOS moding, so I plan to read a lot more of this forum. I'm a pretty okay coder with a lot of embedded experience and I understand SPI flash protocol pretty well through my work with FPGAs. I even have a few friends who work on things like coreboot and I do have plenty of tools for flashing and reading SPI modules. However I have never ventured into the BIOS / UEFI world myself.

My longer term goal would be to be able to understand the following;
* If PCIe bifurcation support could be added to something as old as this motherboard.
* What is going on with TPM support on this board (as the T7600 does seems to have a TPM but the option doesn't appear in the BIOS).
* Why the BIOS seems extremely unreliable with various USB keyboards.
* Why the BIOS doesn't work with one of my NVIDIA graphics cards.
* If I could end up using something like whatever LinuxBIOS is called these days.

This machine is not my primary system, so I'm okay with it being out of operation for periods of time while I fiddle with the BIOS.

Looking forward to learning a lot!
