I work for a financial institution with 70 locations across the midwest. I have about 30 Option 11's. I have found where you can download software versions from the Nortel web site and want to try reinstalling the software on one of the Option 11's. I have an Option 11C on a test bench I can use. I have the CardPro 9 install software. What type of PCMCIA cards should I use? Is there a documented procedure for this? Any help would be appreciated.
