Binary BIOS image labelled for the HP ProBook 4520, delivered as a raw 4.00 MB file that matches a 32 Mbit SPI flash chip. The name gives no board number, revision or firmware version, so its origin should be verified before use. A dump like this is normally written directly to the BIOS chip with a hardware programmer to recover a board that fails to POST or has corrupted firmware. Read and keep the existing contents first, compare the chip marking with the image size, and make sure the PCB really belongs to a 4520.
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 @biosarchive. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
