4 MB BIOS for Gateway and Packard Bell laptops on the NEW71 platform, built on the Compal board LA-5893P and filed under Acer, which owns both brands. Compal uses the LA-xxxxP pattern for its main boards. The dump can be written with an SPI programmer to recover a machine that powers on with no display or is stuck after a bad update. Confirm that the flash chip is 4 MB and the LA number matches the PCB, and keep the original read for its serial data.
