How to change setup defaults? AMI Aptio 4

Hello,

my goal: Change some default/optimized settings in setup after resetting (CMOS reset or battery removed).
For example, S-ATA is always set to “IDE mode” and the date starts at year 2005.

I found 2 instances that contain setup data:

  • AMITSE, File GUID: B1DA0ADF-4F77-4070-A88E-BFFE1C60529A, contains PE32 image section, freeform Subtype GUID: 97E409E6-4CC1-11D9-81F6-000000000000 and “setup”, Subtype GUID: FE612B72-203C-47B1-8560-A66D946EB371

  • Setup, File GUID: 899407D7-99FE-43D8-9A21-79EC328CAC21, contains PE32 image section and freeform Subtype GUID: 97E409E6-4CC1-11D9-81F6-000000000000.

I’ve extracted from “Setup” with IFR extractor (old and new style), but changes i made wasn’t succesful and all setup defaults stayed on the same. Also tried advice from this site which has also no effect: GitHub - BoringBoredom/UEFI-Editor: Aptio V UEFI Editor: an alternative to AMIBCP
Link to UEFI-Editor page: UEFI Editor

For luck, my mainboard has a SPI-header, so it is perfectly for experiments.

Really nobody?

Anyway, i used AMIBCP for changing default-entries and it worked.

But, no option to set the default date (still on 01.01.2005 after reset). The only possible string i found was in freeform Subtype GUID 97E409E6-4CC1-11D9-81F6-000000000000.
Changes from D5 07 01 01 to E8 07 01 01 (=01.01.2024) has no effect.

Any solution how to find the real date?

Next time, at least provide info on mb model, better than just reference to the UEFI editor (For Aptio V mostly…) but with a bios default date (Bios build date/release)… of 2005, shouldn’t be an Aptio V at all… anyway glad you made it, regards.

Forgot it…

It is an iEi IMBA-Q870 (never heard this company before), direct link to vanilla bios-file: https://dls.ieiworld.com/IEIWeb/PDC_APP/PLM/WFP004466-IEI/IMBA-Q870-i2-R10_B270AR42.zip
