Second copy of a 1 MB BIOS image intended for the HP 6720 or HP 550 laptops, according to its name. Apart from the two model numbers, no revision, board or status information is included, so the dump should be treated as unconfirmed. The size matches an 8 Mbit serial flash device. Use it to recover a board with corrupted firmware via an external programmer, but first dump the original chip twice and compare the reads, then check that the board in hand truly belongs to one of these models.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
