// [Symptom]     RBU function is not working
// [Description] 1. The current make file doesn¡¦t build *.hdr file,
//                  we can use that file to verify RBU function under DOS.
//               2. We could build *.hdr file manually, and also verified
//                  the RBU function under DOS. But the RBU function is
//                  not working.

// [Category]    BrugFix
// [Symptom]     Some PEG Lan Cards on NorthBridge would cause hanging
//               issue when waking through them.
// [RootCause]   These Lan cards on NorthBridge do not clear PME for Nb's
//               slots. Therefore, this causes hanging issue.
// [Solution]    Checking if this PEG card is Lan card. If it's, then
//               clear PME status.

// [Category]    BugFix
// [Symptom]     System became resuming from S5 when system is resuming
//               from S4.
// [Description] Reproducing steps (UEFI OS)
//               1. Boot into USB key, run afudos.exe
//               2. Remove USB key.
//               3. Warm reset and don't press any key.
//               4. Screen will show "Reboot and select proper Boot
// device...
//                  No boot option"
//               5. Warm reset and press DEL to enter BIOS setup.
//               6. Change "Launch Video OpROM policy" to "UEFI only".
//               7. Save and reset.
//               8. Press DEL key to enter BIOS setup.
//               9. Change "Launch CSM" to "Disable"
//              10. Save and reset,enter OS(UEFI WIN8)
//              11. Open any file and do "Hibernate" to enter inot S4.
//              12. Power on, resuming back from S4 to desktop, the file
//                  would be disappeared. It looks like it doesn't resume
//                  back from S4 but S5.
// [RootCause]   It's out of variable type for S4 resume.
// [Solution]    The variable type should be
// "PreviousMemoryTypeInformation"
//               but MemoryTypeInformation.
