Request: Set default starting time+date in Setup, iEi IMBA-Q870, Aptio 4

Good morning,

i want to set the default date and time after CMOS-reset to a different value. For example, 01.01.2024 instead of 01.01.2005.

Setup can be extracted with IFR, but my mods in the “freeform Subtype GUID 97E409E6-4CC1-11D9-81F6-000000000000” won’t have any effect and startup date remains on 2005. I found no other strings with date, maybe it is set from NVRAM defaults?

Thanks!

You can try to set the time/date through UEFI Shell.

How to do that?

Usually it is possible to set a value at offset. In IFR output file i found this:

Date: System Date, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x2 {1A 8E 16 00 17 00 02 00 00 00 FF FF 00 10}
Default: DefaultId: 0x0, Value (Date) {5B 0D 00 00 06 D5 07 01 01 00 00 00 00}

How to get the right offset? 0xFFFF seems not to be correct.
