Commodore PC 20 - Starting or Booting MS-DOS

4 Operations Guide
Irning On The Computer
~r The First Time
• External commands - These are commands that are on the
System Disk but are NOT automatically read into the computer's
memory when MS-DOS is loaded. Whenever you want to use one
of these commands, you must access the System Disk.
Starting Or Booting MS-DOS
Starting MS-DOS (also referred to as booting or loading MS-DOS)
is
the process of copying the MS-DOS internal commands from the
System Disk into the computer's memory. (Of course, the full
MS-DOS, including the internal commands, still remains on the
System Disk after the booting process is completed.)
Follow this procedure when you first turn on the computer to start
or "boot" MS-DOS on your Commodore PC system:
1. CHECK THAT YOU HAVE REMOVED ALL PACKING MATERIALS
FROM THE EQUIPMENT.
Make
sure that you have removed the transport cards from the
disk drives. Save these cards in case you have to move the
System Unit at some future time.
2. CHECK THAT THE SYSTEM UNIT IS PROPERLY CONNECTED
TO THE KEYBOARD, THE MONITOR AND THE ELECTRICAL
POWER SOCKET.
3. CHECK THAT THE
SYSTEM UNIT IS PROPERLY CONNECTED
TO ANY PERIPHERAL EQUIPMENT YOU MAY BE USING, SUCH
AS A PRINTER.
4. TURN ON THE MONITOR.
Press
the power switch on the monitor. For most monitors, a
power indicator light on the front of the monitor glows when
the power is on.
5.
MAKE SURE THAT THE SYSTEM DISK HAS A WRITE-PROTECT
TAB OVER THE NOTCH ON ITS SIDE.
The write-protect tab protects the information on the System
Disk from
being accidentally replaced or written over. (See
Figure
9.)
