BIOS image for the HP Compaq CQ41 and Pavilion dv4-2145dx laptops, built on mainboard LA-4117P, delivered as a 1.00 MB ZIP archive. The LA-xxxxP pattern is Compal's board numbering, the ODM that made these HP boards. A 1 MB image corresponds to an 8 Mbit SPI chip, so it will not suit a different-sized flash. Use it to restore a non-booting board with an SPI programmer. Confirm the board number on the PCB, and back up the original contents before writing.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
