    Hi All

    I have a C3640 with 8 mb. Simm flash (with an old IOS image 11.2 etc.) I
    decided to upgrade it with 64 Mb. of RAM, 32 Simm flash, and an IOS image
    12.3 to support extended features as a Wic-1ADSL and so on.
    Wich are the right steps to follow ???

    I tried to install 32 Mb. flash simm first and to load from ROMMON the new
    IOS image using xmodem commands. But after uploaded the IOS when I tried to
    boot the router hangs with error messages ".....cannot load .... cannot find
    the magic number .... and something like that". Maybe the new IOS image is
    to big (about 25 Mb.) but the total amount of the flash is 32 Mb. Should I
    replace the the rom chip too ???

    Thanks all

    Piertonio

    Thank you

    I followed this link ... but the IOS image I own are bad ... so I can't
    upgrade it ... I'd like to find some IOS images with IP extended , and some
    others features such as voice, vpn, and so on...
