In Setup/IFR there is "default" and there is also "default MFG", sometimes they even appear as two choices.
Here is an example:

0x3A64D One Of: PMIC Position, VarStoreInfo (VarOffset/VarName): 0x1CB, VarStore: 0x1, QuestionId: 0x63E, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 07 09 05 09 3E 06 01 00 CB 01 10 10 00 01 00}
0x3A65E One Of Option: Position 1, Value (8 bit): 0x0 (default MFG) {09 07 0A 09 20 00 00}
0x3A665 One Of Option: Position 2, Value (8 bit): 0x1 (default) {09 07 0B 09 10 00 01}
0x3A66C End One Of {29 02}
This is probably covered somewhere here, but I cannot find a definitive answer: what is the meaning of each one in this context?
