This loader canbe started by holding down the action button (the joypad) while resettingthe unit or when powering on. At this point, a blue bird will appear onthe LCD screen. Also at this point, a simple loader can be accessed over theserial port at 115200/8N1. Using this loader, the contents of the iPAQ flashmemory can be saved to a Compact Flash memory card.<DIVCLASS="NOTE"><BLOCKQUOTECLASS="NOTE"><P><B>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 16MBytecard will be required.</P></BLOCKQUOTE></DIV></P><P>Use the "r2c" command to dump Flash contents to the CF memory card. Once thiscompletes, RedBoot can be installed with no fear since the Parrot loader canbe 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, thenHotSync 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 toinstall an application which will run a RAM based version of RedBoot. Oncethis is installed and running, RedBoot can be used to update the flash witha native/ROM version of RedBoot. <P></P><UL><LI><P>Using ActiveSync, copy the file OSloader to your iPAQ. </P></LI><LI><P>Using ActiveSync, copy the file redboot_WinCE.bin to the iPAQas bootldr in its root directory.
