ASUS H81M-C desktop motherboard BIOS, version 3602, in the ASUS CAP capsule format with a size of 8.00 MB. CAP files are normally flashed through EZ Flash in the BIOS setup or via USB BIOS FlashBack where supported, rather than directly with a programmer. Because the capsule carries a header ahead of the actual image, the header must be stripped with a tool such as UEFITool if you intend to write the 8 MB chip externally. Confirm the exact board model before flashing, since H81 variants use different images.
