4. Methods to Implement DLC in a UEFI ISO

| Method | Description | UEFI Compatibility | |--------|-------------|--------------------| | Separate FAT32 partition | DLC stored on USB partition alongside ISO | Excellent (native) | | SquashFS + overlay | DLC as compressed read-only image mounted via overlayfs | Good (Linux only) | | WIM/ESD files | Windows DLC (drivers, updates) injected into boot.wim | Windows PE/Setup | | Network DLC repository | Boot ISO fetches DLC via HTTP/HTTPS | Good (requires network stack) | | Embedded archive | DLC inside ISO but excluded from minimal boot image | Works, but increases ISO size |
