Some operating system kernels, such as Linux, still use triple faults as a last effort in their rebooting process if an ACPI reboot fails. This is done by setting the IDT register to 0 and then issuing an interrupt. [1] Since the table now has length 0, all attempts to access it fail and the processor generates a triple fault.
A software reset (or soft reset) is initiated by the software, for example, Control-Alt-Delete key combination have been pressed, or execute restart in Microsoft Windows. Hardware reset [ edit ]
In Unix and Linux, the shutdown command can be used to turn off or reboot a computer. Only the superuser or a user with special privileges can shut the system down. One commonly issued form of this command is shutdown -h now, which will shut down a system immediately. Another one is shutdown -r now to reboot.
BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...
Windows successfully loaded the device driver for this hardware but cannot find the hardware device. 42: Windows cannot run the driver for this device because there is a duplicate device already running in the system. 43: Windows has stopped this device because it has reported problems. 44: An application or service has shut down this hardware ...
The Client/Server Runtime Subsystem, or csrss.exe, is a component of the Windows NT family of operating systems that provides the user mode side of the Win32 subsystem.In modern versions of Windows, it is primarily involved with process and thread management, console window handling, side-by-side assembly loading and the shutdown process.
If the program is a critical part of the operating system, the entire system may crash or hang, often resulting in a kernel panic or fatal system error, on Windows this can result in a Blue Screen. Most crashes are the result of a software bug .
SysRq may be released before pressing the command key, as long as Alt remains held down. The combinations always assume the QWERTY keyboard layout; [citation needed] for example, on the Dvorak keyboard layout, the combination to shut down the system uses the R key instead of O. Furthermore, some keyboards may not provide a separate SysRq key.
