Thanks for the help. I ran the program using Wine; does the output look okay?
$ wine PMPatch.exe WinFlash/BIOS1.WPH out.wph
fixme:heap:HeapSetInformation (nil) 1 (nil) 0
PowerManagement module not found.
Nested PowerManagement module not found.
Nested PlatformSetupAdvancedDxe.efi at 006C6F60 patched.
Nested PowerManagement2.efi module at 001800F8 patched.
Dell RAW file checksums corrected.
CpuPei module not found.
I just want to be sure that I'm not going to brick my motherboard.
Edit; Also, opening the .wph file in the Phoenix BIOS Editor produces an error, is this normal? The error is that it thinks the file is bigger than expected.
Edit2: Do I need to be running this on the .wph file, or the actual updater .exe?
