Firmware archive for an Intel-based board code-named Cedar, Wistron motherboard 13269-1, with PWB number FX3MC at revision A00. The PWB code and the A00 revision follow Dell's style of labelling, while the 13269-1 number follows Wistron's pattern, identifying the ODM that built the board. The 4.42 MB ZIP is meant for reprogramming the SPI BIOS chip with an external programmer. Match the 13269-1 number and the revision on the PCB, and back up the existing chip before flashing.
