Raw 4 MB BIOS binary named only n5010, most likely a Dell Inspiron N5010 system, though the name carries no board number, revision or version. A 4 MB image corresponds to a 32-megabit SPI flash chip and is written with an external programmer when the board does not POST. Dell boards of this generation were built by several ODMs, so match the PCB number before use. Save a copy of the current chip first, since service tag and other system data live in the original.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
