Working BIOS image for an HP notebook built on Compal board LA-J952P; the name gives no model or revision. The file is a 14.4 MB RAR archive, so extract it and compare the binary with the capacity of the flash chip fitted to your board before programming. Compal identifies its boards with LA- numbers printed on the PCB, and that marking is the most reliable reference for compatibility. Back up the original firmware with an SPI programmer first, then write the dump to revive a corrupted or bricked system.
