Update: Adding a driver to a UEFI firmware

[DiMeneses]

The guide present in the wiki doesn't seem to work anymore, as I can't find any .rsrc folder in vmware-vmx.exe.

Is this dependent on any vmware version? If so, which one?

Is there any other alternative? I can't find any open source efi.rom to add my DXE Driver to. Maybe I'm just using the wrong keywords.

Thank you for your attention.

I'm afraid I no longer use VMWare and I don't have the time to perform any research to update the guide. Like most documentation, this is time dependent of the software that existed at the time it was written.

Mostly the VMWare UEFI firmware was used as an example of how one can inject an NTFS driver, but the goal is not to be a comprehensive guide that will apply to everything. As such, I'm afraid you will have to do your own research if you want to apply it to different software than the one that was used for this example.

No problem, it also served as a heads up.

If I come up with an alternative solution I'll post it here in case you want to update the guide with it.

Proposed update

• Package your .efi driver as per the efifs instructions: "Creating the UEFI firmware module".
• With UEFITool, press ctrl+O to open an OVMF.fd (open virtual machine firmware) image.
• You can find the latest build of OVMF here, under the name edk2.git-ovmf-x64-0.
• Use ctrl+F to GUID search for 961578FE-B6B7-44C3-AF35-6BC705CD2B1F.
• Double click the "GUID pattern" message at the bottom.
• Right-click to insert after the Fat Dxe Driver.
• Choose your .ffs file.
• Press ctrl+S to save the image.
• You can choose a new name such as yourOVMF.fd or override the previous image.
• Test it with QEMU:

  qemu-system-x86_64 -bios yourOVMF.fd -net none
