    problem solved.

    The cf card was not formatted properly.

    Format the card by HOST PC using a card reader.

    'df -h ' to check which dev node this card is mounted. Mine is on /dev/sdb

    fdisk /dev/sdb

    follow the command helper.

    five things needs to be done.
    1 create two partitions, one is fat16 and the other one is ext2.
    2 change to partition type by issuing command 't' and an HEX value (fat16 is 6, linux ext2 is 83)
    3 assign the fat16 partition as the primary boot partition
    4 write and sync your card by issuing 'w' command
    5 quit

    then copy the files to compact flash as described in the user manual
