BIOS package for the ASUS G531GD, labelled ROG Strix Hero II in the name, with the tokens 9th and 305 that most likely refer to a ninth-generation Intel platform and BIOS version 305. The name marks it as a fixed outimage, meaning a full SPI flash image prepared for direct writing with a programmer. Unpack the RAR, compare the image size with the flash chip on the board, and save a read of the original chip first so the serial data and any working settings can be restored if needed.
