computer is shut down completely, hard disk stops spinning, several seconds elapse at least before a restart is attempted.

Restarting CP/M from scratch, typically caused by pressing a RESET button.

A cold boot is the process of starting up the computer from a floppy disk. No programs are allowed to load into memory other than those included on the floppy. Many authorities believe the only way to ensure that a computer is free of viruses is to perform a cold boot immediately followed by a virus scan.

The process of starting the computer by turning on its power. See also Boot, Cold Reboot, Reboot, Warm Reboot..

when a computer is first turned on.

One of two ways to boot the reader; compare to warm boot. A cold boot invokes the BIOS boot sequence, which verifies that the 256K flash system image is not corrupt, clears all memory, and performs a complete power-on self test (POST) to ensure that the hardware and peripherals are operational. The cold boot initializes the system hardware for use by system software, loads the default configuration, runs AUTOEXEC.BAT and CONFIG.SYS, and loads DOS. Because the physical RAM drive is initialized, all files on drive E are lost. You may cold boot the reader to clear the reader's conventional memory, break out of an application that is locked in an infinite loop, or recover from an error condition.

Starting the computer from a power-off status. If your computer is off, and you turn the switch on, you're performing a Cold Boot.

Booting a PC after it had been turned off (and usually cooled off). Unlike a warm boot, this completely deletes the content of the RAM and therefore also removes any memory-resident viruses.

The process of starting-up a computer from a floppy disk, so that no other programs can load into memory besides those directed by the boot software contained on the floppy. Because viruses must go resident in order to damage, and some viruses are particularly good at "stealthing" themselves while in memory, many experts believe a cold boot, followed by a scan, is the only way to make certain a computer is virus-free.

See boot. Cold boot also refers to a jump to the boot entry. point in the BIOS jump table.

A system start up initiated by turning on the systems power switch. [] The COM port is another name for the serial port, which is so-called because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another). Parallel ports transmit the bits of a byte on eight different wires at the same time (that is, in parallel form, eight bits at the same time).

Process of turning on a computer after it has been powered off completely. 8.4

The process of starting a computer by turning on the power to the system unit.

A startup process that begins with turning on the computer's power. Typically, a cold boot involves some basic hardware checking by the system, after which the operating system is loaded from disk into memory.

Starting or restarting a computer by turning on the power supply. See also warm boot.

When the system is restarted using the power on button.

To start the computer by cycling the power. A cold boot using a rescue disk (a clean floppy disk with boot instructions and virus scanning capabilities) is often necessary to clean or remove boot sector infectors. See Also: Boot, Warm Boot

The first time power is applied to a product, or a hard reset.

Refers to the boot-up when the system has been turned off for a period of time. Every time you turn your computer on you are performing a cold boot.

Starting the computer by turning on the power or pressing the RESET button. A cold boot makes the processor execute all of the diagnostics. See boot and warm boot.

Start the computer by switching on the power. A cold boot recycles the computer' s random access memory (RAM), thus removing any viruses that might be present in memory.

Starting the computer after turning it off completely (see warm boot).

Booting the system from power off. Same as hard boot.
