Any computer is equipped with a system timer connected to the interrupt request line IRQ0. It can be easily controlled and, if desired, disabled. The timer is visible at the very bottom of the desktop, as it is directly a component of it.
Necessary
a computer with a timer installed on it
Instructions
Step 1
Please note that if the timer on your computer is running normally, you will not be able to manipulate its controls using the Enter button. To open access to the control, close the program and restart it again. The timer interface is made in the style of the Winamp Modern skin, so it's not difficult to use it at all. Usually it is implemented on such microcircuits as Intel 8254 or Intel 8253. Each of these microcircuits has its own computer. For example, the Intel 8254 chip is designed for the IBM AT and IBM PS / 2 computers, and the Intel 8253 chip is for the IBM PC and IBM XT computers.
Step 2
To stop the timer completely, you must invoke the Windows Task Manager by pressing the key combination Ctrl + Alt + Del or Ctrl + Shift + Esc. In the list that opens, find the process named Stoppc and click the "End Process" button. After this command, the timer on your computer will be immediately disabled. It is worth noting that before turning off the timer completely, ask yourself if the situation really requires it, since turning it off is always much easier than restoring it
Step 3
In addition to manual shutdown, the timer can turn off automatically as soon as it completes the specified task (hibernation of the computer or its blocking). If the timer does not require a complete shutdown, then simply collapse it into the system tray (tray), using the "Minimize" button on the top panel. Working in hidden mode, the timer disappears from the desktop after starting. In addition, the timer can be interrupted by its handler, which controls the operation of the floppy drive motors, and also increases the value of the four-byte variable, each time, by one current value at the address 0000: 046Ch located in the bios data area.
