MODBOOT is modular boot disk. All programs and files are placed in modules. Adding functionally to your disk is as simple as copying one file (module) to the correct folder.
An example: to add Dos mouse support to your MODBOOT disk you just copy the module called "mouse.cab" to the "\level1" folder on your boot disk.
All MODBOOT modules are packed using cabinet (.cab) files so a MODBOOT disk can hold as much data as possible. To expand a .cab file you simply put it in the right folder and modboot will unpack it for you. When the .cab file has an "\autorun.bat" modboot will automatically execute it.
