Compressed firmware for the AN52D board, around 351 KB. No BIOS version, chipset or flash chip details are given in the name. Other members of the AN52 family have separate files, so confirm the D suffix on the PCB before use. Typical application is recovering a motherboard after an interrupted update, writing the image through the vendor tool or directly to the chip with a programmer. Keep a copy of the original contents, and verify the image size matches the chip to avoid an incomplete write.
