><P
>The board manufacturer provides a DOS application which is
capable of programming the flash over the PCI bus, and this is
required for initial installations of RedBoot. Please see the board
manual for information on using this utility.  In general, the process
involves programming one of the two flash based RedBoot images to
flash. The ROM mode RedBoot (which runs from the flash boot sector)
should be programmed to flash address 0x00000000. The ROMA RedBoot
mode (which is started by the ARM bootloader) should be programmed to
flash address 0x00004000.</P
><P
> To install RedBoot to run from the flash boot sector, use the manufacturer's
flash utility to install the ROM mode image at address zero.</P
><P
>To install RedBoot to run from address 0x40000 with the ARM bootloader
in the flash boot sector, use the manufacturer's flash utility to install
the ROMA mode image at address 0x40000. </P

>RedBoot can coexist with ARM tools in flash on the IQ80310 board. In
this configuration, the ARM bootloader will occupy the flash boot sector while
RedBoot is located at flash address 0x40000. The sixteen position rotary switch
is used to tell the ARM bootloader to jump to the RedBoot image located at
address 0x40000. RedBoot is selected by switch position 0 or 1. Other switch
positions are used by the ARM firmware and RedBoot will not be started. </P
