Parameters

Parameter Description
{on | off | edit} Specifies the value for Emergency Management Services redirection, including:
  • on. Enables remote output for the specified <osentrylinenum>. Also adds a /redirect option to the specified and a redirect=com<X> setting to the [boot loader] section. The value of com<X> is set by the /port parameter.
  • off. Disables output to a remote computer. Also removes the /redirect option to the specified and the redirect=com<X> setting from the [boot loader] section.
  • edit. Allows changes to port settings by changing the redirect=com<X> setting in the [boot loader] section. The value of com<X> is set by the /port parameter.
/s <computer> Specifies the name or IP address of a remote computer (don't use backslashes). The default is the local computer.
/u <domain>\<user> Runs the command with the account permissions of the user specified by <user> or <domain>\<user>. The default is the permissions of the current logged on user on the computer issuing the command.
/p <password> Specifies the password of the user account that is specified in the /u parameter.
/port {COM1 | COM2 | COM3 | COM4 | BIOSSET} Specifies the COM port to be used for redirection. The BIOSSET parameter directs Emergency Management Services to get the BIOS settings to determine which port should be used for redirection. Don't use this parameter if remotely administered output is disabled.
/baud {9600 | 19200 | 38400 | 57600 | 115200} Specifies the baud rate to be used for redirection. Don't use this parameter if remotely administered output is disabled.
/id <osentrylinenum> Specifies the operating system entry line number to which the Emergency Management Services option is added in the [operating systems] section of the Boot.ini file. The first line after the [operating systems] section header is 1. This parameter is required when the Emergency Management Services value is set to on or off.
