<title>Starting the System</title>
<para>
To start up OS-9 follow these steps:

<orderedlist numeration="arabic">
<listitem><para>Turn the &make; and disk drive(s) on. You should see
the usual BASIC greeting message on the screen.</para></listitem>

<listitem><para>Insert the OS-9 System Disk in drive zero and close the door.</para></listitem>

<listitem><para>Type &quot;&DOSCMD;&quot;. After a few seconds of disk activity you should
see a screen with the words &quot;OS9 BOOT&quot;.</para></listitem>

<listitem><para>OS-9 will then begin
its &quot;bootstrap&quot; loading process, which
involves ten to twenty seconds of disk activity. When the system
startup has finished, a message followed by the shell prompt will be
displayed.</para></listitem>

<title>A Quick Introduction to the Use of the Keyboard and Disks</title>
<para>
For now, the only special keys on the keyboard of interest are
the SHIFT key which works like a typewriter shift key; the ENTER key
which you always use after typing a command or response to OS-9; and
the &lt;- left arrow key which you can use to erase typing mistakes.
</para>
<para>
Your main disk drive is known to to OS-9 as &quot;/D0&quot; and is often
called &quot;drive zero&quot;. If you have a second disk drive (drive one),
OS-9 recognizes it as &quot;/D1&quot;. Why would anybody put a &quot;/&quot; in a name?
Because all input and output devices have names like files, and
names that start with &quot;/&quot; are always device names.
</para>
</section>

<section>
<title>Initial Explorations</title>
<para>
When OS-9 first starts up, it will display a welcoming message,
and then ask you to enter the date and time. This allows OS-9 to
keep track of the date and time of creation of new files and disks.
Enter the current date and time in the format requested like this:
<screen>
            yyyy/mm/dd hh:mm:ss
     Time?  2003 03 01 14 20
</screen>
In the example above, the date entered was March 1, 2003. OS-9
uses 24-hour time so the date entered was 1420 hours or 2:20 PM.
Next, OS-9 will print the shell prompt to let you know it is ready
for you to type in a command.
</para>
<para>
Now you're ready to try some commands. A good first command to
try is DIR (for &quot;<emphasis>dir</emphasis>ectory&quot;).
This will display a list of the files
on the System Disk. Just type:
<screen>
dir
</screen>
followed by a &quot;return&quot;. OS-9 should respond with a listing of file
names which should look something like this:
<screen>
 OS9Boot     startup     CMDS      SYS      DEFS
</screen>
The file &quot;OS9Boot&quot; contains the OS-9 program in &CPU; machine
language, which was loaded into memory during the bootstrap
operation.
</para>
<para>
The file &quot;startup&quot; is a &quot;command file&quot; which is automatically run
when the system starts up, and has the commands that printed the
welcoming message and asked for the time. Later, You may want to
replace this startup file with your own customized version after you
are more familiar with OS-9. Do you want to see the contents of
this file? If so, just type
<screen>
list startup
</screen>
As you can see, the LIST command displays the contents of files
that contain text (alphabetic characters). Some files like the
&quot;OS9Boot&quot; file contain binary data such as machine language
programs. These files are called &quot;binary files&quot;, and attempts to
list them will result in a jumbled, meaningless display. On the
other hand, OS-9 will complain mightily if you try to run a text
file as a program!
</para>
<para>
As you may have surmised by now, the way you ask OS-9 to run a
program or command (they're really the same thing) is to simply type
its name. Some commands like LIST require one or more names of
files or options. If so, they are typed on the same line using
spaces to separate each item.
</para>
<para>
But where did the LIST and DIR programs come from? There are
really more files on the disk than you suspect. The DIR command
showed you what is the disk's
<emphasis>root directory</emphasis> - so named because the
OS-9 filing system resembles a tree. Growing out of the root
directory are three &quot;branches&quot; - files which are additional
directories of file names instead of programs or data. They in turn
can have even more &quot;branches&quot; - ad infinitum. If you draw a map on
paper of how this works it does look like a tree.
</para>
<para>
The directory files on your system disk are called &quot;CMDS&quot;,
&quot;SYS&quot;, and &quot;DEFS&quot;.
The file &quot;CMDS&quot; is a directory that consists of
all the system commands such as DIR, LIST, FORMAT, etc. To see the
files contained in this directory, enter:
<screen>
dir cmds
</screen>
which tells DIR to show files on the directory file CMDS  instead
of the root directory. After you type this you should see a long
list of file names. These are the complete set of command programs
that come with OS-9 and perform a myriad of functions. Chapter
Seven explains each one in detail. The DIR command also has a handy
option to display the CMDS  directory with less typing:
<screen>
dir -x
</screen>
Whenever you want a list of available commands you can use this so
you don't have to look it up in the book. The DIR command has
options which can give you more detailed information about each file.

<title>Making a Backup of the System Disk</title>
<para>
Before getting too much more involved in further experimentation,
NOW is the time to make one or more exact copies of your System Disk
in case some misfortune befalls your one and only master System
Disk. Making a backup involves two steps: formatting a blank disk
and running a backup program.
</para>
<section>
<title>Formatting Blank Disks</title>
<para>
Before the actual backup procedure can be done (or any fresh
diskette is used for any purpose), the blank disk which is to become
the backup disk must be initialized by OS-9's FORMAT command.
</para>
<para>
IF YOU HAVE ONLY ONE DISK DRIVE you have to be extra careful not to
accidentally FORMAT your system disk. Type:

<screen>
format /d0
</screen>

and when you see the message

<screen>
COLOR COMPUTER FORMATTER
FORMAT DRIVE /D0
Y (YES) OR N (NO)
Ready?
</screen>

immediately remove your system disk and insert a blank disk
<emphasis>before</emphasis> you type &quot;Y&quot;.

IF YOU HAVE TWO DISK DRIVES place the blank disk in drive one and
type:
</para>
<screen>
FORMAT /D1
</screen>
<para>
WHEN THE BLANK DISK IS IN THE RIGHT PLACE, type &quot;Y&quot;, then &quot;ENTER&quot;.
This initiates the formatting process. IF THE CORRECT DEVICE NAME
(/D1) IS NOT DISPLAYED: TYPE N  RIGHT NOW and start over, OR YOU
MAY ERASE your System Disk.
</para>
<para>
When you are asked for a disk name, type any letter, then ENTER.
The name you give is not important. If you have only one drive,
replace the system disk after the FORMAT program has finished. If
the FORMAT program reported any errors, try again. Disks used for
backups can't have any errors. You're now ready to run the BACKUP
program.
</para>
<para>
It takes several minutes for the FORMAT program to run. During
its second phase the hexadecimal number of each track will be
displayed as it is checked for bad sectors. If any are found an
error message for each bad sector is given.
</para>
</section>

<section>
<title>Running the Backup Program</title>
<para>
The BACKUP program makes an exact duplicate of a disk. It can be
used even if you only have one disk drive.
</para>
<para>
IF YOU HAVE ONE DRIVE type
</para>
<screen>
backup /d0 #32k
</screen>
<para>
The BACKUP program will prompt you to alternately insert the source
disk (the system disk) and the destination disk (the freshly
formatted disk).
</para>
<para>
IF YOU HAVE TWO DRIVES type
</para>
<screen>
backup #32K
</screen>
<para>

The BACKUP program will respond with
</para>
<screen>
Ready to BACKUP from /D0 to /D0 (or /D1) ?
</screen>
<para>
Now enter Y  for yes. It will then ask:
</para>
<screen>
X is being scratched
OK ?:
</screen>
<para>
Answer &quot;Y&quot; for yes again, and the BACKUP process should begin.
</para>
<para>
The BACKUP command has two phases: the first phase copies
everything from drive zero to drive one checking for errors while
reading from the master but not for &quot;write&quot; errors. The second
phase is the &quot;verify&quot; pass which makes sure everything was copied
onto the new disk correctly.  If any errors are reported during the
first (copy) pass, there is a problem with the master disk or its
drive. If errors occur during the second (verify) pass, there is a
problem with the new disk and the BACKUP program should be run
again. If BACKUP repeatedly fails on the second pass, reformat the
disk and try to BACKUP again. If BACKUP fails again, the disk is
physically defective.
</para>
<para>
After you have made your backup disk, try turning the &make;
off and restarting the system with the copy you just made.
If it works OK, store it in a safe place in case it is needed later.
You should always have a backup copy of your system disk and all
other important disks.
