How to access the UEFI Shell?

GMN New Member Posts: 20

I have a UP2, recently updated to BIOS UP-APL01 R5.0 (UPA1AM50).

It reports compliancy with UEFI 2.5; PI 1.4

However, I cannot seem to get access to the UEFI Shell. The setup BOOT options do not even have a menu item for selecting boot to the internal UEFI Shell, so what do I need to do to gain access to the Shell?

    I just found out that F7 will open a different menu that allows selection of the UEFI Shell. I had been pressing ESC to enter setup.

    That said, my OS loader still cannot access ShellProtocol.

    status = pBS->LocateProtocol(&guidShellProtocol, NULL, (void**)&pShell);

    status 14 - EFI_NOT_FOUND

    on UP Squared UEFI shell is not present, you would need to add a EFI application that will boot from USB with EFI Shell.

    You can find that application inside the BIOS update packages for UP Squared in our download section

    The Shell IS present on my UP2. I just need to press F7 as soon as the AMI BIOS logo appears.
