/CLKLVL
Causes the standard x86 multiprocessor HAL (Halmps.dll) to configure itself for a level-sensitive system clock rather then an edge-triggered clock. Level-sensitive and edge-triggered are terms used to describe hardware interrupt types.
/CMDCONS
Passed when booting with into the Recovery Console (described later in this chapter).
/crashdebug
This switch loads the kernel debugger when you start the operating system. The switch remains inactive until a Stop message error occurs. /crashdebug is useful if you experience random kernel errors. With this switch, you can use the COM port for normal operations while Windows is running. If Windows crashes, the switch converts the port to a debug port. (This action turns on remote debugging.)

/debug
This switch turns on the kernel debugger when you start Windows. The switch can be activated at any time by a host debugger that is connected to the computer, if you want to turn on live remote debugging of a Windows system through the COM ports. Unlike the /crashdebug switch, /debug uses the COM port whether you are debugging or not. Use this switch when you are debugging problems that are regularly reproducible.

/debugport=comnumber
This switch specifies the communications port to use for the debug port, where number is the communications port, such as COM1, that you want to use. By default, /debugport uses COM2 if it exists. Otherwise, the switch uses COM1. If you include this switch in the Boot.ini file, the /debug switch becomes active.

/EXECUTE
This option disables no-execute protection. See the /NOEXECUTE switch for more information.
/fastdetect:comnumber
This switch turns off serial and bus mouse detection in the Ntdetect.com file for the specified port. Use this switch if you have a component other than a mouse that is attached to a serial port during the startup process. For example, type /fastdetect:comnumber, where number is the number of the serial port. Ports may be separated with commas to turn off more than one port. If you use
