Archive for the HP Pavilion g6-1b50us built on board 6050A2412601, revision MB-A02. The 6050A prefix follows the Inventec numbering scheme, the ODM manufacturing this board for HP. The 1.2 MB RAR's contents are not stated, though likely a BIOS dump or service data for this board. Firmware images are programmed onto the SPI flash with an external programmer; schematics or boardviews help trace rails and locate parts. Check the board number and revision on the PCB first and back up the original chip.
