RCUnlocker version 1.0, a 4.80 MB RAR archive associated with HP in the index. The name only gives the tool name and version, so its exact function and supported models should be confirmed from the files inside before use. Utilities of this kind are generally used in firmware service work on locked or protected machines. As with any tool that changes BIOS or EC contents, read and store a full backup of the original SPI chip with a programmer first, and confirm the target model matches the 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 @CLRINDORE. Enginerys does not host this file.
