Additional copy of a 4.00 MB firmware image for the HP 455 G1 laptop, with no board number, revision or version stated in the name. It may be a duplicate or a read from another unit, so comparing it with the first file is sensible. The size fits a 32 Mbit SPI flash, written using an external programmer. Before flashing, back up the existing chip, which may carry serial and product data, and check that the board printed number matches the source machine for this dump.
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.
