<title>Initial Installation Method </title>
<para>It is possible to install RedBoot in one of two ways. Either as
the primary bootmonitor on the board (installed to blocks 0-1 of the
flash) or as the secondary bootmonitor on the board (installed to
blocks 1-2 of the flash).</para>

<para>Presently, only the former method is supported.</para>
<!--   Nuke the above line if uncommenting this block
<para>When installed as the secondary bootmonitor, the ARM bootmonitor
remains in flash and auto-executes RedBoot (but only when RedBoot is
smaller than 128KB - which means it cannot include the LCD driver).
It is of crucial importance that no RedBoot configured to be
primary bootmonitor is executed on a board where RedBoot is actually
supposed to be the secondary bootmonitor since it may cause corruption
of the flash. Installing RedBoot as the primary booter is
adviced.</para>

Download the RAM mode image of RedBoot configured as a primary

<screen>boot Monitor &gt; <userinput>m</userinput>
Load Motorola S-Record image into memory and execute it
The S-Record loader only accepts input on the serial port.
Record addresses must be between 0x00008000 and 0x01E0F510.
Type Ctrl/C to exit loader.
</screen>

Use the terminal emulator's ASCII upload command, or (on Linux) simply
cat the file to the serial port:

<screen>$ <userinput>cat redboot_primary_RAM/redboot.srec &gt;/dev/ttyS1</userinput>
</screen>

You should see RedBoot start up:

As can be seen from the output above, the network has been configured
to give the board an IP address and information about the default
server. If things are not set up on your network, you can still
continue, but use the Y-modem download method when loading the RedBoot
ROMRAM mode image.

Now initialize RedBoot's FIS:

<screen>RedBoot&gt; <userinput>fis init</userinput>

</screen>

Download the ROMRAM mode image of RedBoot via ethernet:

<screen>RedBoot&gt; <userinput>load -b %{FREEMEMLO} redboot_primary_ROMRAM/redboot.srec</userinput>
</screen>

or using serial Y-modem protocol:

<screen>RedBoot&gt; <userinput>load -mode ymodem -b %{FREEMEMLO}</userinput>
</screen>

(Use the terminal emulator's Y-modem upload command to send the file 
<filename>redboot_primary_ROMRAM/redboot.srec</filename>.)

When the image has been downloaded, program it into flash:

<screen>Address offset = 0x00ff8000
