What are the BOOT.INI switches and their functions?

Microsoft Windows XP, Microsoft Windows XP OEM Upgrade, Windows XP Tablet PC Edition

/SAFEBOOT with MINIMAL - Safe Mode

/SAFEBOOT with NETWORK - Safe Mode with Networking

Note: This does not load the customer's network configuration, but instead loads a generic TCP/IP network configuration.

/SAFEBOOT with DSREPAIR - Directory Services Restore Mode (Domain Controllers Only)

/SAFEBOOT with MINIMAL (ALTERNATESHELL) - Safe Mode with Command Prompt

/NOGUIBOOT - When this option is specified, the VGA video driver responsible for presenting bitmapped graphics during the Microsoft® Windows® XP startup process is not initialized. The driver is used to display startup progress information and to print the blue screen crash screen, so disabling it disables Windows XP ability to do those things.

/BOOTLOG - Enable Boot Logging. This is the mode to use when you are debugging problems that are regularly reproducible.

/BASEVIDEO - The computer starts up using the standard VGA video driver. Use this switch if you have installed a graphics driver that is not working.

/SOS - Displays the driver names while they are being loaded. Use this switch if Windows does not start up and you think a driver is missing.

BOOT.INI Advanced Options

/MAXMEM= - Specifies the maximum amount of RAM that Windows can use. This switch is useful if you suspect a memory chip is bad.

/NUMPROC= - Only enables the first n processors on a multiple processor system.

/PCILOCK - Stops Windows from dynamically assigning IO/IRQ resources to PCI devices and leaves the devices configured by the BIOS.

/DEBUG - Debugging Mode

/DEBUGPORT= - Specifies the communications port to use for debugging. Also used with the /BAUDRATE= and /CHANNEL= switches.

/BAUDRATE= - Specifies the baud rate to be used for debugging. If you do not set the baud rate, the default baud rate is 9,600 if a modem is attached, and 19,200 for a null-modem cable. /DEBUGPORT must have a COM port selected for this to be an option.

/CHANNEL= - Specifies the 1394 communication channel to use for debugging. It does not matter which 1394 connector the cable is plugged into. /DEBUGPORT=1394 must be selected for this to be an option.
