Firmware archive for a Wistron-made board numbered 10245-1, labelled with the DQ15 project code and marked UMA, meaning integrated graphics with no discrete GPU. The name gives no laptop brand or model, so identify the target by the board number on the PCB. The 2.14 MB RAR presumably contains an SPI dump for reprogramming the BIOS chip with a hardware programmer. Back up the existing chip first, do not use it on a discrete-graphics variant, and verify the image size against the flash chip.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
