3745 boot problems

    I'm having problems booting a 3745 from the internal flash card. The router came from ebay with a 32 Meg internal CF card and booted without any problems. I installed a new Cisco 64 Meg card (part number 16-2647-02) and installed a new version of IOS. The system won't boot from the internal flashcard now. I've tried using both erase and format before coping the image to the CF card. I get different error messages at boot time but the same result, it won't boot up on it's own. If I use the ROMMON boot command it boots and runs just fine from both the internal and slot0 CF cards. I've tried a couple of different IOS versions and the end result is the same.

    Checksum error, file not found???? The ROMMON dir command finds the file just fine and it boots just fine from the command line:

    And it works just fine after the manual boot.

    Is there something I need to do before or after the format or erase commandon the 3745? I got two of the 64 Meg CF cards, the other I put in a 2691 and it works just fine.

    Thanks
