Data type Range Default value
REG_SZ String There is no default value for this entry.


Stores special instructions for startup. Windows 2000 receives these instructions from the firmware (ROM) in RISC-based systems and from Boot.Ini in x86 computers.

For example, if you select the VGA option at startup, the value of SystemStartOptions is BASEVIDEO SOS. BASEVIDEO is the VGA mode for display drivers. SOS directs the system to display each driver as it loads during startup, rather than displaying a series of dots.

If you change the value of this entry by using a registry editor, your changes will be overritten by the value specified in the Boot.ini file the next time the computer starts.
