Uncompressed 4 MB BIOS image for the HP Pavilion DV3-4303SE, for the Intel version with ATI graphics, marked OK as a tested working dump. The 4.00 MB size corresponds to a 32 Mbit SPI flash chip, so check the chip marking on your board matches that capacity. Load the .bin into programmer software such as for a CH341A or RT809 and write it to the BIOS chip. Make sure the graphics variant is the same, and read and keep the original chip contents before erasing.
