HP Omen 15 BIOS dump for Quanta board DAG3DCMBCC0, revision C, with 08574 and DMI in the name suggesting the image carries DMI data such as serial and system identifiers. The archive is a 7.03 MB RAR. Quanta uses the DA plus project code plus MB pattern for its boards. A dump with DMI from another unit may need serial data edited to match the laptop. Back up the original chip before programming and confirm the board number and revision on the PCB.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
