Firmware dump covering the Dell Vostro 3449 and 3549, built on Wistron mainboard 13302-1. Wistron typically identifies Dell boards with a five-digit number plus a dash suffix like this one, printed on the PCB. The 4.72 MB RAR contains a BIOS image to be written to the SPI chip with a programmer such as a CH341A when the machine does not post. Read the original chip and keep the copy, as it contains service tag information, and ensure the dump size matches the chip capacity.
