BIOS dump for the HP ProBook 4420s with an Intel Core i5, labelled display, a tag commonly used for the main BIOS that brings back video output. The file is 4.00 MB, fitting a 32 Mbit SPI flash, and the name gives no board number. Program it with an external SPI programmer when a board powers on but stays on a black screen due to corrupted firmware. Verify the motherboard number on the PCB matches this model and save the existing chip contents before you erase it.
