Greetings all

I have been following this thread with  interest as I am new to AVR and am
about 3 weeks into using my new STK500.
The 'fuse gotcha' issue seems to have got me today when I plugged in a new
Mega8 and changed an oscillator fuse so as to run using the STK500 onboard
clock. I set the fuse for external clock i.e.. Ext. Clock; StartupTime: 6CK
+ 64 ms;[CKSEL = 0000 SUT = 10]

Obviously this was a mistake as I am now locked out and assume the part is
now useless. Please can someone advise what the fuse setting should have
been to allow the mega8 to run using the STK500 onboard clock.

Many thanks
Ian
