Re: Changing clock source in AVR?

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.

High Voltage Parallel Programming with an STK500 always works.
