The free version supports full driver integration.
1. Extract driver files from EXE's using 7-Zip,
innoextract, or using some command-line that's only known to other users on your OEM's forum.
2. On the right is the HW checklist for the host. NTLite is checking if the loaded image is missing drivers for devices matching this host.
If your target system has different HW, then ignore the "Missing" flags.
With the licensed version, you can auto-import the host's driver files into the image without searching folders.
