| Symptom | Probable Cause | Solution | |---------|----------------|----------| | Error 280 – Module not inserted | Volume full or unaligned | Delete a small, unused module first (e.g., a legacy video BIOS) | | BIOS saves but system won’t POST | Wrong volume insertion location | Move the module to Volume 01 (Early DXE) instead of Volume 04 (Late DXE) | | NVMe drive not listed in boot menu | Driver loaded but BootOrder not updated | Use bootice or efivar to manually add NVMe boot entry | | MMTool crashes on load | Corrupted BIOS dump or wrong file size | Use Binwalk to verify file structure; redump BIOS with programmer | | “Image is not an Aptio UEFI volume” | BIOS is Insyde or Phoenix, not AMI | MMTool only works with AMI Aptio. Use UEFITool for other types |
