address space. With this switch, user mode programs can access 3 GB of memory instead of the usual 2 GB that Windows allocates to user mode programs. The switch moves the starting point of kernel memory to 3 GB. Some configurations of Microsoft Exchange Server 2003 and Microsoft Windows Server 2003 may require this switch.

/basevideo
Ключ /basevideo позволяет загружаться с использованием основного стандартного драйвера VGA (640x480, 16 цветов). Этот режим полезен, если причиной неправильной загрузки Windows является новый драйвер для видеоадаптера. Основной драйвер видеоадаптера всегда используется при загрузке в безопасном режиме («Безопасный режим», «Безопасный режим с загрузкой сетевых драйверов» или «Безопасный режим с поддержкой командной строки»). Причиной сбое может быть неправильное разрешение экрана и частота развертки. Можно для удобства также использовать в связке ключ /sos.
/baudrate=number
This switch sets the baud rate of the debug port that is used for kernel debugging. For example, type /baudrate=9600. The default baud rate is 9600 kilobits per second (Kbps) if a modem is attached. The default baud rate is 115,200 Kbps for a null-modem cable. 9,600 is the normal rate for remote debugging over a modem. If this switch is in the Boot.ini file, the /debug switch is automatically enabled.

/bootlog
При использовании данного параметра система записывает в файл WindowsNtbtlog.txt перечень всех драйверов и служб, которые были загружены (или не загружены). При загрузке компьютера в безопасном режиме, в безопасном режиме с загрузкой сетевых драйверов и в безопасном режиме с поддержкой командной строки в журнал загрузки добавляется список всех загружаемых драйверов и служб. Журнал загрузки полезен для определения точной причины неполадок при загрузке системы.
/bootlogo
Используется собственный экран загрузки в Windows XP или Windows Server 2003, вместо стандартного экрана с бегающей полоской индикатора. Предварительно следует создать 16-цветную растровую картинку размером 640x480 пикселов и сохранить ее в папке Windows под именем Boot.bmp. Затем добавить в boot.ini ключи '/bootlogo /noguiboot'.
/break
Causes the hardware abstraction layer (HAL) to stop at a breakpoint at HAL initialization. The first thing the Windows kernel does when it initializes is to initialize the HAL, so this breakpoint is the earliest one possible. The HAL will wait indefinitely at the breakpoint until a kernel-debugger connection is made. If the switch is used without the /DEBUG switch, the system will Blue Screen with a STOP code of 0x00000078 (PHASE0_ EXCEPTION).
/burnmemory=number
This switch 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. For example, type /burnmemory=128 to reduce the physical memory that is available to Windows by 128 MB.
/CHANNEL=
Used on conjunction with /DEBUGPORT=1394 to specify the IEEE 1394 channel through which kernel debugging communications will flow. This can be any number between 0 and 62 and defaults to 0 if not set. Use this switch together with the /debug switch and the /debugport switch to configure Windows to send debug information over an Institute of Electrical and Electronics Engineers, Inc. (IEEE) 1394 port. To support debugging over a 1394 port, both computers must be running Microsoft Windows XP or later. The 1394 port has a maximum number of 63 independent communications channels that are numbered 0 through 62. Different hardware implementations support a different number of channels across one bus. Windows XP has a limit of four destination computers. However, this limitation is removed in Windows Server 2003. To perform debugging, select a common channel number to use on both the computer that the debugger runs on, which is also known as the host computer, and the computer that you want to debug, which is also known as the destination computer. You can use any number from 1 to 62.
To configure the destination computer
1. Edit the Boot.ini file to add the /CHANNEL=x option to the operating system entry that you have configured for debugging. Replace x with the channel number that you want to use. For example, configure the [operating systems] area of the Boot.ini file to look similar to the following:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS='Windows Server 2003, Enterprise' /fastdetect /debug /debugport=1394 /CHANNEL=3
2. Plug the 1394 cable in one of the 1394 ports.
3. Disable the 1394 host controller on the destination computer. To do this, start Device Manager, right-click the device, and then click Disable.
4. Restart the computer.
To configure the host computer
1. Plug the 1394 cable in one of the 1394 ports.
2. Install the kernel debugger binary files.
3. Start a command prompt. Press enter after you type each of the following commands:
set_NT_DEBUG_BUS=1394
