GAG allows you to boot up from a choice of 9 different operating systems. It can boot operating systems installed in primary and extended partitions on any available hard disk.

It doesn't need its own partition. It installs itself in the first track of the hard disk, which is reserved for this type of program. It has a timer to boot a default operating system (selectable by the user).

Hides the primary partitions which allows the user to have installed more than one DOS and/or Windows in the same hard disk. Can exchange disk drives, allowing to boot from the second, third... hard disk operating systems such as MS-DOS. Supports a great variety of keyboards (QWERTY, AZERTY, QWERTZ and DVORAK keyboards). Full support for hard disks up to 4 terabytes (4096 gigabytes).
