BIOS .bin 1.00 MB Shared

BIOS dump for the Intel version of the HP Pavilion dv4, built on the Compal LA-4105P motherboard. The 1.00 MB raw file matches an 8 Mbit SPI flash chip. It is meant for writing directly to the BIOS chip with a programmer such as CH341A to recover a laptop that no longer boots. Compal uses the LA-xxxxP pattern for its laptop boards and prints it on the PCB, so confirm the number there. Always read and store the existing dump before erasing, and check the result for a valid boot.

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.
