Default fuse settings for Diecimila / Mega168? Moderators: adafruit_support_bill, adafruit

I was messing around with the Diecimila connected via ISP to my STK500 and borked the fuses to the point where I needed to use HVPP to unbork it. Somewhere along the line, I think I've set the clock incorrectly, because now I can't upload a sketch in the Arduino IDE (I did re-program the bootloader, just in case). AVRStudio tells me that the fuses read 0xF8, 0xDD, 0xCF, which has the clock set at CKSEL=1111 SUT=00.

It may be late and I'm tired, but a google of "arduino default fuses for mega168" doesn't give me much information on what the fuses should be. Can someone give me a reading on their fuse settings? Thanks!

Just choose "Tools>Burn bootloader" in the Arduino IDE. It writes the fuses before burning the bootloader. That should write the default values.

Is there any documentation on how to use the Arduino IDE to burn the bootloader using an STK500? Because it does not work as you suggest:

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: successfully opened stk500v2 device -- please use -c stk500v2
avrdude: stk500v2_command(): command failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

I know the STK500 works fine, because I can use it within the AVRStudio environment.
