programming atmega168 boot with parallel prog ?

Hello, I built the parallel programmer and succesfully programmed the atmega8 bootloader with uisp.
I am now trying to program the atmega168 but keep getting a lot of flash errors.

Any advice?

i had similar problems a few days ago with my custom parallel port gizmo. double check the values of your resistors and the quality of your solders. the fact that you don't have more errors means your thing is mostly working but you might have a short or something.

are you saying - and this isn't clear - that this same parallel port thing you made was successful a programming an atmega8 but now fails with an atmega168?

Hey,
I have actually been following your threads about programming the atmega168, they were very helpful. I did program the atmega8 with the parallel programmer without any problems. I will check my cable again, but went ahead and bought a serial programmer from sparkfun.
