Version 6.5 of NetBootDisk has been released. It has 98 different drivers on the disk. It runs from a floppy, CD or USB flash drive.

You can do manual or automatic image/restore operations with Ghost2003 or Image for DOS.

For example, I can plug a USB flash drive into my son's computer, press the power button to start his computer and walk away. When I return his WinXP partition has been restored. (The backup image is stored in my computer)
