BIOS for the HP Pavilion dm4-1209tx laptop, built on board 6050A2317701-MB-A01, packed in a 1.31 MB rar file. The 6050Axxxxxxx pattern is used by Inventec, the ODM behind many HP notebooks, with MB-A01 giving the board revision. Such a dump is written to the SPI flash with a hardware programmer when the laptop powers on without display or the firmware is corrupted. Check the board number on the PCB, back up the existing chip and ensure the image size equals the flash capacity.
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.
