    See http://www.lancos.com/siprogsch.html, the siprog is just a few zeners and resistors, and with true serial port works pretty fast, it programs the chip over the ISP header. With usb to serial converter it works too, but is very slow.
    I use it too for programming I2C eeproms and other stuff, very versatile.

    edit: you can forget d1,d2,d3 c3,c12,c4 and u3 since you will have normal power supply anyway.

    Looks like a nice development board for AVR.

    To program it via RS232, you need a bootloader inside the AVR first. There are plenty of cheap ISP programmers on the net and I've used this one which I bought recently:

    The 10 pin plug seems compatible with your development board. There are also plenty from China and HK with "free shipping".

    Hello

    1.Thanks for the replay, i have now have borrowed a AVR dragon, and have got connected over Jtag :), will try to fix the bootloader(any hint about this?)

    2.i Alsow have borroved a AVRISP MK2, can i use this? (i think so, but the connector on that one, dosen't fit my board(there is 6 pins on the AVRIPS, which sould i use?")

    best regards Ronny
