hp 840

BIOS 16.0 MB Shared

Second copy of a 16 MB firmware dump marked only as HP 840, presumably an EliteBook 840, although the generation such as G1, G2 or G3 is not stated. That omission matters because each generation uses different boards and firmware. The size fits a 128 Mbit SPI flash. Before programming with an external programmer, confirm the exact generation and board number on the PCB, save the original chip contents, and verify the write, since a mismatched image will leave the laptop dead.

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 →
