The Windows NT operating system, if supplied, is factory-installed on the system disk. Windows NT factory installedsoftware (FIS) saves you time when installing the system,because you do not need to install the operating system.

BootingWindows NTAutomatically

When the system is shipped with Windows NT FIS, the systemdefault settings cause the system to boot from the system diskautomatically after it successfully completes its power-up tests.However, the system counts down for 10 seconds after it displaysthe Boot menu before booting. You can stop the system frombooting before this time-limit expires by choosing another menuitem by pressing the up arrow key or down arrow key.

You can change these system default settings if you want. Forexample, you can cause the system to halt at the Windows NTfirmware Boot menu after it completes its power-up tests, or youcan increase the count down time-limit.

Boot Selections The Windows NT firmware uses boot selections to identifythe location of the operating system files. When the systemis shipped, the default boot selection identifies the systemdisk as the location of the operating system files. This bootselection causes the system to boot from the system disk. Youcan set alternative boot selections if, for example, you wantto boot the operating system from a different device. See theCustomer Technical Information manual for information onsetting alternative boot selections.
