BIOS and ITE embedded controller firmware for a board identified as GRANGE92 with number 6050A3108201-MB-A01, revision A1. The 6050A pattern is Inventec numbering, so the ODM is Inventec regardless of the laptop brand. The 14.2 MB archive should include separate images for the BIOS flash and the ITE EC chip; match each to its chip by size. Dump both originals with a programmer before writing and verify the PCB carries the A01 marking.
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.
