Thanks for helping me! Tried just L"Load.efi", but still no luck. I'm
starting to research LoadImage and StartImage to use instead of the
ShellLib, but Load Image needs the EFI_DEVICE_PATH_PROTOCOL for my efi
image and that seems hard to figure out how to get.
Here is what my screen looks like:
============================
fs1:\> Load.efi
Inside Load.efi
fs1:\> Test.efi
ImageHandle: B86D1218
ShellInitialize: Success
ShellExecute: Invalid Parameter
fs1:\>
============================
Here are my .inf files, by the way:
