Original BIOS read of 4.00 MB for an HP dv6-series notebook, carrying a GRN marker that is not explained in the name. No board number, chipset or revision is stated, so compatibility must be checked against the unit. A 4 MB image corresponds to a 32 Mbit SPI flash. Technicians write such factory-style dumps with an external programmer to recover from failed updates or corrupted firmware. Save the existing chip contents first, verify identical chip capacity, and match the PCB board number before relying on it.
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 →
