For a harddisk the code in the Master Boot Record first sector determines the active partition. The code in the boot sector of the active partition could then be again a NTLDR boot sector looking for ntldr in the root directory of this active partition. In a more convoluted scenario the active partition can contain a Vista boot sector for the newer Vista boot manager with an ntldr entry pointing to another partition with a NTLDR boot sector. When booting, the loader portion of NTLDR does the following in order Accesses the file system on the boot drive either FAT or New Technology File System, NTFS.

Activating this option may break VMR 9 video. Activating this option may also cause audio problems with Creative SB X Fi series sound cards with X Fi Gamer X Fi Titanium WINXP 3.

VGA mode by using a video device driver that is compatible with any video adapter. If the operating system fails to load due to a faulty or incorrectly configured video driver, this switch allows the system to load, so the user may then remove, update, or roll back the video driver causing the problem. Using this switch in conjunction with the SOS switch helps to determine the driver that is triggering a failure. BAUDRATEnnn Sets the baud rate of the debug port that is used for kernel debugging. Use of this switch automatically enables the DEBUG switch. Specifies an override for the default baud rate 1. Example BAUDRATE1. BOOTLOG Turns on boot logging to a file named System. RootNtbtlog. txt. BOOTLOGO Displays an alternate 6. The bitmap must be saved in the Windows directory with the name boot. Use with the NOGUIBOOT switch. BURNMEMORYnnn Specifies the amount of memory, in megabytes, that Windows cannot use. Use this parameter to confirm a performance problem or other problems that are related to RAM depletion. CHANNELnn Use with the DEBUG switch and the DEBUGPORT1. IEEE 1. 39. 4 interface channel numbered 0 to 6. CRASHDEBUG Loads the kernel debugger at OS startup, but it remains inactive until a Stop error occurs. With this switch, the COM port can be used 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 Turns on the kernel debugger when Windows starts.
