The only option you have is autoboot to get the full CPU frequency. These machines have a complicated way to setup the full CPU frequency and I do not know if it is worth hacking here when one can get the value with autobooting. Here in the last section 'Booting into FreeBSD' you find how to do this. http://people.freebsd.org/~nwhitehorn/ppcinstall.txt Hope this helps. Andreas
