BIOS image for L500 and L582 models built on board 6050A2250401-MB-A03, with RT10MG noted in the name, possibly a firmware or project tag. The 6050A numbering belongs to the Inventec pattern, so the ODM is Inventec even though the laptop brand differs. The 1 MB file has no extension but should be a raw dump for an 8 Mbit SPI chip. Confirm the A03 revision on the PCB, then back up the existing flash before writing this image with a programmer.
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 @bios_laptop. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
