Brennprobleme beim Mega8 und Mega88

Beim Versuch einen Mega8 oder 88 mit mehreren Programmen 
(avrdude,eXtreme Burner)zu beschreiben erhalte ich folgende
FEHLERMELDUNG (Kurzfassung):
avrdude.exe: auto set sck period (because given equals null)
avrdude.exe: verification error, first mismatch at byte 0x0000
             0x3b != 0x00
avrdude.exe: verification error; content mismatch

Brennhardware USBasp von Radig/Fischl mit Konfiguration lt. Anleitung

Benutzer Befehl:
C:\WinAVR-20100110\bin>avrdude.exe -C 
C:\WinAVR-20100110\bin\avrdude.conf -p m88 -P /dev/parport0 -c usbasp 
-v -U flash:w:C:\Temp\MrData.hex:a

Was mache ich falsch?
