Raw 4 MB firmware dump identified only as pg55t, a short code that probably refers to a board or model, though the name does not confirm what device it fits. No brand, revision or region details are given, so cross-check the code against the board silkscreen before using it. Raw .bin images like this are written straight to a 32 Mbit SPI flash with a programmer such as a CH341A. Always save the original chip first, because it may hold serial numbers and network address data that a donor image lacks.

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 →
