->The Windows/CE environment originally shipped with the iPAQ contains a hidden
-mini-loader, sometimes referred to as the "Parrot" loader. This loader can
-be started by holding down the action button (the joypad) while resetting
-the unit or when powering on. At this point, a blue bird will appear on
-the LCD screen. Also at this point, a simple loader can be accessed over the
-serial port at 115200/8N1. Using this loader, the contents of the iPAQ flash
-memory can be saved to a Compact Flash memory card.

->NOTE: </B
->We have only tested this operation with a 32Mbyte CF memory card.
-Given that the backup will take 16MBytes + 1KByte, something more than a 16MByte
-card will be required.</P
-></BLOCKQUOTE
-></DIV
-></P
-><P
->Use the "r2c" command to dump Flash contents to the CF memory card. Once this
-completes, RedBoot can be installed with no fear since the Parrot loader can
-be used to restore the Flash contents at a later time.</P
-><P
->If you expect to completely recover the state of the iPAQ Win/CE environment, then
-HotSync should be run to backup all "RAM" files as well before installing RedBoot.</P
-><P
->The next step in installing RedBoot on the iPAQ actually involves Windows/CE,
-which is the native environment on the unit. Using WinCE, you need to
-install an application which will run a RAM based version of RedBoot. Once
-this is installed and running, RedBoot can be used to update the flash with
-a native/ROM version of RedBoot. <P

-you to press certain keys. Using the stylus, press and hold until the prompt
-is withdrawn. When you lift the stylus, RedBoot will continue with the next
-calibration. </P

->Once the LCD touchscreen has been calibrated, RedBoot will start. The
-calibration step can be skipped by pressing the <SPAN
