Second copy of an HP 8460 firmware image, presumably from the EliteBook 8460 series, though the name gives only the number. It is an 8 MB dump without extension or notes on ME state, version or test status, so treat it as an unverified raw read. A chip of 64 Mbit capacity is needed to hold it. Compare it with the other copy in a hex editor, keep a backup of the original flash, and verify the write with the programmer software after flashing the SPI chip.
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 →
