BIOS together with EC firmware for an HP 15 notebook on Compal board LA-G078P revision 1.0, with EPV51 given as the platform code in the name. The 5.47 MB RAR should hold the system BIOS image plus the separate embedded controller file, useful when a board will not power on or charge after corruption. LA-xxxxP numbers are Compal's scheme. Match the board number and revision on the PCB, back up both the BIOS SPI chip and EC flash with a programmer, and verify each image size against its chip.
