We strongly recommend that you backup your existing firmware when given the option.  This gives you the option of restoring your old code if you experience any problems with the new rev.


IMPORTANT NOTE FOR BITWARE USERS:
For users who received Cheyenne Bitware with their modems you need to replace the modems.inf file that came with Bitware in order for your modem to be properly recognized by Bitware.  To do this from Win 95/98 select Start / Windows Explorer.  (Windows 3.1 users select Main / File Manager.)  Go to the directory that you ran Flashcom from and select 'modems.inf'.  Now drag this file to the Bitcom directory.  (To drag the file click on the modems.inf file and hold the left mouse button down.  Move the mouse to the Bitware directory and release the left mouse button.)  Windows will prompt you to replace the existing file click yes.

For users of 01Communicate it is not necessary to do this as 01Communicate will automatically recognize the modem.


Updating your Modem to the Latest Code

1.  From Windows 95/98 do Start / Run.  From Window 3.1/3.11 do File / Run.
2.  Browse to the directory that you unzipped the files in and run Flashcom.
3.  After Flashcom detects your modem it will give you the option to backup your existing firmware.  We strongly recommend that you do this.  This will allow you to return to your previous version of firmware.
 

For Windows 95/98 users you will need to update your modem driver.  To do this follow the steps bellow.


To remove your old modem drivers from Windows 

1.  Select Start / Settings / Control Panel and double-click Modems.
2.  Select the Diagnostics tab.
3.  Select the COM port which is associated with your modem.
4.  Click the More Info button.
5.  Find the name of the modem and the identifier which is underneath the modem’s name. Write down the OZOxxxx number, such as OZO8030.
6.  Now select OK in each window to return to the Control Panel. Leave the Control Panel open.
7.  Click Start  / Find / Files or Folders.
8.  Leave the Named field empty.
9.  In the Look in field, Browse to C:\Windows\Inf\Other. If this directory doesn't exist then browse to C:\Windows\Inf.
10. Select the Advanced tab.
11. The Of type field should say All Files and Folders.
12. In the Containing text field enter the OZOxxxx number you wrote down for your modem.
13. Click the Find Now button, and Windows will search the files for your modem.
14. Delete the file(s) that Windows found.   
   

You’ve now removed your modem’s drivers.  Now you want to uninstall your modem.


Removing Your Modem From The Modems Control Panel

1.  Select Start / Settings / Control Panel
2.  From the Control Panel double-click Modems.
3.  Select your modem then choose remove.

Now to reinstall your driver you need to reboot your computer.  After it reboots it will detect your modem as new hardware and look to install the driver.  Browse to the directory that Flashcom is in so Windows can find the driver.
