Firmware archive for the Acer TravelMate 5310, naming Wistron as the board maker and Dellen as the platform or project name. The RAR is 532 KB, consistent with an older, small-capacity BIOS chip. Wistron builds many Acer notebooks and labels projects with code names like this. Before flashing, check the project name and board number on the PCB, read and save the existing contents with a programmer, and verify the dump size equals the chip capacity.
