Firmware dump for a Wistron board code-named MOCKINGBIRD-L, Comet Lake (CML) platform with discrete graphics (DIS), board 19709-1 and code J85JT; 19746-2 is also linked in the metadata. The 8L token likely means an 8-layer PCB, though the name does not explain it. Wistron uses five-digit numbers with a dash revision, and J85JT looks like a Dell-style part code. Verify the board number on the PCB, back up the SPI flash first, and check the image fits the chip.
