BIOS image for the ASUS ROG Strix X399-E Gaming motherboard, version 0503, supplied in a 4.4 MB RAR archive. The X399 platform supports AMD Threadripper processors on socket TR4. A technician can use the file to recover a board through an external programmer when the firmware is corrupt, or compare it with a damaged dump. ASUS retail images may need conversion before direct chip writing, so check the size against the flash chip. Back up the original chip before making changes.
