AlphaBIOS boots Windows NT in two stages. The first stage involves reading an OS
Loader program from a disk. The OS Loader program is named OSLOADER.EXE.
The selection for the operating system must describe the path where AlphaBIOS will
find the OS Loader program. The OS Loader program must be located on a partition
formatted with the FAT file system.
Once the OS Loader program executes, it uses the services provided by AlphaBIOS
to load the operating system components. After the operating system is loaded, the
OS Loader starts execution of the operating system.
