I have a Olimex devboard AVR-P28B with a ATMEGA8 on it. I programmed and used it just fine when it was running on the internal RC oscillator. But I wanted to try to get it working on the 4Mhz crystal so I set the fuse bits and wrote those. Problem is, now it doesn't work anymore and I can't get it to respond and change the fuse bits.
How can I program the fuse bits in this situation? I assumed that the programming interface always runs off the RC-clock otherwise a wrong write could render the device useless but I think that's not the case.
