Firmware archive for an HP 250 G4, the name lists ABQ52 and the code 080C6 alongside Compal board LA-C811P revision 1.0; it is a 3.45 MB RAR. The extra codes are not explained in the name, so treat them as identifiers to compare against the label or previous dump rather than assumptions about content. Compal LA-series boards are widely shared across HP budget lines, so the PCB code is the reliable match. Use a programmer to write the SPI chip only after reading out and saving the original contents, and verify the image size fits the flash.
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.
