    I tried to flash a Cisco 678 from CAP cbos 2.4.6 to DMT cbos 2.4.6

    Yes, I know it is ancient, but in a couple of months my ISP is going to
    offer wireless, so I don't want to buy a new DSL modem for only a
    couple months of use.

    My session is copied below. the reboot gives errors as listed at the
    bottom. I used hyperterminal to communicate from the serial port toe
    the exc port to transfer the nsrouter.c678dmt.full.2.4.6.bin file.
    That seemed to go fine, but I got errors on reboot.

    Any ideas? - Thanks in advance...

    I finally got my DSL operating over the weekend. The key item was
    indeed flashing the firmware in my Cisco 678 from CAP to DMT. I used
    hyperterminal. The session seemed to go per plan, but the first time I
    had some intersting error lines on bootup:

    Hello!
    Checking CBOS Flash CRC...
    MIX header/trailer not found
    Checking Monitor
    MIX header/trailer CRC verified: 0x14a39663

    Checking Custom Config Flash CRC...
    MIX header/trailer not found
    Operation fault at fee00000, subtype 01
    Fault record is saved at 10001010

    SO I tried the download procredure again and now the modem boots fine

    I am surprised that Qwest never informed me that all new lines are
    installed as DMT even though they still apparently support existing
    customers with CAP.
