BIOS package for the HP ZBook Studio G4, board LA-E251P revision 1.0, holding three images sized 16 MB, 8 MB and 1 MB, in a 14.5 MB ZIP. LA-xxxxP numbering marks Compal as the ODM. Several SPI chips are used on such boards, so pair each image with the chip of matching capacity. Read and keep every original chip before writing with a programmer, and confirm the board number and revision on the PCB agree with the file.
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.
