About whether this project can read data during the BIOS/UEFI stage.

I want to read some data in the BIOS/UEFI stage, but I'm not sure if this project can be done well. I have tried many times, but failed. Perhaps there is a technical problem with me. Can you answer me?

It is possible to do so when either VTD is turned off or VTD is turned on and IOMMU pre-boot is disabled

It would depend on your system.

If the system have an always on preboot iommu this project won't work unfortunately.
