Hi!
I bought two ATMega8 parts (Chinese store, you can easily guess it), previously I also bought two ATtiny85 (works well), but I have a problem with these ATMega8. I saw on the internet that I have to load the bootloader on it, and I can do this with another Arduino board (at most I could borrow an FTDI from a friend, that`s all I have). I tried as shown here:

I didn't succeed at all, it always gives me the error that it can't load the bootloader. I installed everything I needed. With ATtiny85 I succeeded. What else to try?
