I don't know which tools to use to control it automatically, but here are instructions for manual use: By default, the fan should run at full speed. If you need to regulate the speed, you need to locate the pwm files in /sys: find /sys/ | grep pwm /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm2 /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm1 If you want to stop the fan, you have to write the value zero to these files: echo 0 /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm2 echo 0 /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm1 You can activate full speed using the following commands: echo 255 /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm1 echo 255 /sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e/pwm2 See http://www.debonaras.org/wiki/Info/N2100FanControl for a shell script that regulates the fan by reading system and disk temperatures. Fan control has only a very small control range, and the script needs to be tuned for that, but when that is done it works just fine.

Almost bricked my N2100
Hallo! Through no fault of my own (obviously!), my Thecus N2100 no longer has a working initrd in flash. On bootup I get: RAMDISK: Couldn't find valid RAM disk image starting at 0. No filesystem could mount root, tried: cramfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) I have access to RedBoot and have successfully used TFTP to download files into RAM, so to me it looks as if it should be easy to recover from: load -r initrd -b 0x0080 fis load -kernel exec -c console=ttyS0,115200 root=/dev/ram0 initrd=0xa080,42M [EMAIL PROTECTED] and then force the initrd to be rebuilt and re-flashed. I have two questions for you, my learned audience: 1. Is there a ready-made initrd in one of the debian packages that is more-or-less usable with the standard (and up-to-date) Debian distribution? 2. What do I need to do in terms of dpkg and apt commands to force the initrd and kernel to be reflashed?
