We have planned to upgrade our core 3662 ISR to IDS/FW/3DES software. We have purchased 256MB of RAM and 64MB of Flash as per recommendation of our dealer.
Since the flash is empty, the router is thrown into ROMMON and complains about a valid magic number. I could not figure out a way to load the IOS through ROMMON on the 3662 - I don't seem to be able to TFTP it or anything like that, so I resorted to XMODEM... It uploads the image and then gives me an error and quits, here is the error:
---------------------------------------

*I am uploading the IP feature set because it's much smaller than the FW/IDS/3DES software and is used for booting up the system at least.
So am I doing something wrong, or has Cisco shipped me defective FLASH?
