/crashdebug

The /crashdebug parameter establishes a kernel debugger connection, but does not enable debugging unless a bug check occurs. Until then, the port that is usually reserved for debugging is free for other uses.

This option is designed for Windows 2000 and Windows XP. For Windows Server 2003, use the /debug=disable parameter. For details, see /debug.


    /crashdebug [/debugport=COMx] [/baudrate=BaudRate] 

   

Subparameters

/debugport

Specifies the serial port used by the kernel debugger for crash-only debugging.

COMx

Specifies a communications port on the computer. Valid values for COMx are any valid COM port, such as COM1 or COM2. The default is the highest enumerated port.

/baudrate

Specifies the speed of the kernel debugger connection.

BaudRate

Specifies the speed of the kernel debugger connection in bits per second (BPS). Valid values for BaudRate are 9600, 19200, 38400, 57600, and 115200. The default is 19200.

Comments

This parameter is useful for debugging random kernel errors.

If a boot entry includes both /debug and /crashdebug, the /debug parameter is ignored.

Examples


multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /crashdebug

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /crashdebug /debugport=COM1 /baudrate=57600

Bootcfg Commands


bootcfg /raw "/crashdebug" /A /ID 1
bootcfg /raw "crashdebug /debugport=COM1 /baudrate=57600" /A /ID=2
