Upgrading Firmware via the Serial Port
You can upgrade system firmware by connecting your computer to
the serial port on the agent module, and using a console interface
package that supports the XModem protocol.
1. Restart the system by using the Restart System command.
2. When the system initialization screen appears as shown below,
press "D" to download system firmware, and then indicate the
code type (1: Runtime, 2: POST 3: Mainboard).
For example, if you select 1 (for downloading agent firmware), the
system will display the following message:
3. Change your baud rate to 115200 bps, and press Enter to enable
download mode. From the terminal emulation program, select
the file you want to download, set the protocol to XModem, and
then initialize downloading.
If you use Windows HyperTerminal, disconnect and reconnect
to enable the new baud rate.
