    lets just say that in atmel evaluation board
    (AT89STK-11) i succeed to download the hex file to the Flash and it worked fine.
    but now i'm using keil eval board (MCB251) and i want to do the same thing with the same uC: AT89c51RE2.
    directly from keil software i couldn't succeed and also from the FLIP software.

    so how can i do that simple thing and finally start doing my job ?

    thanks
