Then run the following commands:
 cd /usr/bin/
 wget http://kano-kun.net/AntS1/cgminer-ants1-4.3.2a-85fcf0c
 chmod +x cgminer-ants1-4.3.2a-85fcf0c

If you haven't done an update like this before (or undid the change):
 mv cgminer cgminer.original
 ln -s cgminer-ants1-4.3.2a-85fcf0c cgminer

If you HAVE done an update like this before and cgminer.original has
already been saved, then:
 rm cgminer
 ln -s cgminer-ants1-4.3.2a-85fcf0c cgminer

Next you need to restart cgminer on your AntS1
You can restart it, when logged into your ant, with the command
 /etc/init.d/cgminer restart
