How do i update it in minepeon?
Sorry for the noob question
Your best bet is to use the prerelease Minepeon 0.2.5 PR2 that includes BFGMiner 3.10.0 already.
You can find links to it in the sourceforge download list linked from the Minepeon site or forums.
Once you have that running, your settings are incorrect for set-device for the Antminer. This is one that works:
/usr/bin/screen -dmS miner /opt/minepeon/bin/bfgminer -S antminer:all -S erupter:all --set-device antminer:clock=x0981 -c /opt/minepeon/etc/miner.conf
Switch out your preferred clock setting and make sure you don't delete the new shell script sleep settings that were added in the newer Minepeon build.
