Firmware archive for the HP ProBook 650, with the name mentioning G1 and the board code 6050A2566301-MB-A04, where A04 is the board revision. The 6050A prefix is the pattern used by Inventec for its motherboards, a common HP supplier. Compare the code on the PCB sticker with this one before use. Unpack the RAR with any archiver, verify the image size matches the SPI flash, and keep a backup of the original chip before programming it with a CH341A or similar tool.
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.
