    I have a 5329.
    I have CF Flasher on my WIndows PC.
    I have a image.bin file.

    What address do I need to write my image to in order to
    have it (i.e., lunix) boot when the board is powered up?

    OK. I found and used dnfl. This command will download an image
    to flash. Then you use gfl to "go" from flash.

    Now my problem is that the MACADDR of the network interface
    is bogus when I boot from flash.

    Also, autoboot is not implemented on this board.

    Any ideas on how to get around these issues?

    I am not sure what you are referring to exactly. This walkthrough helped me to get to a functional image

    I don't know what auto boot is. Perhaps you are referring to automatically booting to the linux image on power up? Typically you would load the image from flash into ram and then jump to it. You can flash a script into lolo that does that. Go take a look at the lolo docs here,
