BIOS dump for the HP 455 G1 notebook, a 4.00 MB binary. The name gives no board number, revision or firmware version, so confirm the motherboard before use. A 4 MB image matches a 32 Mbit SPI flash chip, which is programmed with a CH341A or comparable tool after desoldering or via a test clip. Technicians use such files to restore boards that fail to POST after a bad update. Always read and keep the original chip contents first, and verify the written data against the file.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
