2.   Upgrading your Firmware

	2.1. Please disconnect all computers from the MIH-120 other than the
	     one that will be acting as an interface during the upgrade 
	     procedure. Verify that your TCP/IP configurations are correct and
	     that the interface computer is directly connected to the MIH-120.

	2.2. If you already have an upgrade file named "code.BIN" please trash
	     this file so there will be no confusion when you begin uploading 
	     the new firmware file (called "cd_mih120_v117d.BIN").

	2.3. Double-click the icon TFTP Client for XRouter.  Then Verify that
	     the IP address, Password, and FileName fields are correct.

	     NOTE: The IP address and Password of your MIH-120 should be change
	           back to the default setting before upgrading the firmware. 

	2.4. Click UPGRADE to start uploading the new MIH-120 firmware.  A 
	     progress bar should appear displaying the status of the firmware
	     upload process. 

	2.5. After the upload process is finished, you must reset the power on
	     the MIH-120 to let the new  firmware take effect. To do this, 
	     simply disconnect the MIH-120's power supply, located on the back
	     panel of the unit, and reconnect it.

     If you have any difficulties loading the new firmware onto your MIH-120,
     please repeat steps 2.2 to 2.5 or refer to "Trouble-Shooting the Upgrade
     Process" in this Read Me. 

3.   PPPoE (Point-to-Point Protocol over Ethernet)

     - PPPoE is a now being used by some ISPs in certain areas to connect customers to 
       their DSL network.  If you are currently using a login program (in some areas: WinPoet,
       MacPoet, or EnterNet) to connect to your ISP's DSL network, please follow the steps
       below to connect via PPPoE.  (Note: The XRouter will now assume the role of your login 
       software.  Therefore, further use of the login software is not required to use your XRouter.)

     - To Connect via PPPoE:

     3.1 Enter the Web based configuration page of the XRouter.  Please refer to the user's 
         manual on this procedure if necessary. 

     3.2 Click on the PPPoE link in the Advance menu.

     3.3 Click on the Enable button for PPPoE.

     3.4 Enter your username and password provided by your ISP in the appropriate fields. 

     3.5 Click on the Connect-on-demand button. (This will allow the XRouter to automatically
         connect upon an Internet request).

     3.6 Click the Apply button to save the changes made. 

     - For further information on PPPoE, please download the newest user's manual located at: 
       http://www.macsense.com/Service/manual/index.html


3.   Trouble Shooting the Upgrade Process

	- If you get an error stating that the file can not be opened, click
	  the "..." side button next to the  file name field. Then locate and
	  select the "cd_mih120_v117d.BIN" file. 

	- If you get an error stating that the XRouter is not responding, check
	  your TCP/IP settings.  You might want to reboot your machine in order
	  to release your TCP/IP numbers (this will refresh the connection 
	  between the MIH-120 and your computer). You may want to unplug and 
	  replug the power plug for the MIH-120  in order to reset the TFTP 
	  server to a ready state.

	- If the Ready/Test LED is flashing, this is an indication that the
	  firmware upgrade has failed to load properly. If this happens, run
	  the program over and reboot by unplugging the unit. This should stop
	  the flashing LED and reset the device.
