Hello, I just tried booting the hard drive from my old G5 on the new one, which is a PowerMac G5 Quad[1], according to specs. tingo@kg-g5$ uname -a FreeBSD kg-g5.kg4.no 9.0-CURRENT FreeBSD 9.0-CURRENT #119 r217462M: Sat Jan 15 16: @comporellon.tachypleus.net:/usr/obj/powerpc.powerpc/usr/src/sys/GENERIC powerpc However, this model doesn't seem to have the necessary hardware for the fcu driver: root@kg-g5# sysctl dev.fcu sysctl: unknown oid 'dev.fcu' It does have something called Apple SMU: root@kg-g5# sysctl dev.smu dev.smu.0.%desc: Apple System Management Unit dev.smu.0.%driver: smu dev.smu.0.%pnpinfo: name=smu compat=smu dev.smu.0.%parent: nexus0 dev.smu.0.fans.drive_bay_a_intake.minrpm: 1000 dev.smu.0.fans.drive_bay_a_intake.maxrpm: 4000 dev.smu.0.fans.drive_bay_a_intake.rpm: 4001 dev.smu.0.fans.backside.minrpm: 1100 dev.smu.0.fans.backside.maxrpm: 3000 dev.smu.0.fans.backside.rpm: 3000 dev.smu.0.fans.cpu_a_intake.minrpm: 485 dev.smu.0.fans.cpu_a_intake.maxrpm: 3200 dev.smu.0.fans.cpu_a_intake.rpm: 3192 dev.smu.0.fans.cpu_b_intake.minrpm: 485 dev.smu.0.fans.cpu_b_intake.maxrpm: 3200 dev.smu.0.fans.cpu_b_intake.rpm: 3197 dev.smu.0.fans.cpu_a_exhaust.minrpm: 500 dev.smu.0.fans.cpu_a_exhaust.maxrpm: 3200 dev.smu.0.fans.cpu_a_exhaust.rpm: 3201 dev.smu.0.fans.cpu_b_exhaust.minrpm: 500 dev.smu.0.fans.cpu_b_exhaust.maxrpm: 3200 dev.smu.0.fans.cpu_b_exhaust.rpm: 3199 dev.smu.0.fans.cpu_a_pump.minrpm: 1250 dev.smu.0.fans.cpu_a_pump.maxrpm: 3600 dev.smu.0.fans.cpu_a_pump.rpm: 3594 dev.smu.0.fans.cpu_b_pump.minrpm: 1250 dev.smu.0.fans.cpu_b_pump.maxrpm: 3600 dev.smu.0.fans.cpu_b_pump.rpm: 3637 dev.smu.0.fans.expansion_slots_intake.minrpm: 1560 dev.smu.0.fans.expansion_slots_intake.maxrpm: 4500 dev.smu.0.fans.expansion_slots_intake.rpm: 4505 dev.smu.0.sensors.slots_power: 17216 dev.smu.0.target_temp: 55 dev.smu.0.critical_temp: 90 dev.smu.0.server_mode: 1 But just reading that doesn't quiet the fans. How do I control the fans on this PowerMac G5 model?
