RuSmi driver for RU.EXE to access UEFI variable in DOS

I have created a driver called RuSmi that enables access RU.EXE to access UEFI variables in DOS.

Please get the file from Github
Password:10072767


It contains following files:
  • FFS format:
    RuSmiFramework.ffs - Used with PI < 1.1
    RuSmiPi.ffs - Used with PI >= 1.1
  • EFI format:
    RuSmi.dxs - dependency file
    RuSmiPi.efi - driver
Please note you will get only variables with runtime attribute in DOS because it is runtime.

Hi James,

1. Are files you provided built for x64?
2. Is it a SMM driver?

Best regards,
Gary

Hi Gary,

1. Yes, I forgot to mention it is X64.
2. The MODULE_TYPE of EDK II INF should be DXE_SMM_DRIVER.

Hi Gary,

I never try to load it from Shell, I just include it in BIOS build process. I will check it later.

Gary,

I think you can get the latest RU.EFI and it should've fixed this exception error.

Hi James,

I am trying to link this driver on Carrizo / Skylake (APTIO V) but got below error. I don't know if it needs re-build for EDK2, or ... (I guess it's built on APTIO 4)

GenFds...
RuSmi.inf(...): error 3001: Framework SMM module doesn't support SMM or SMM_CORE FV file type
