Re: Problems with Fan - full Speed - Debian Wheezy Powermac G5

I am sorry, the post was not complete,

wanted to say that i tried the command that i took of the Debian homepage, but unfortunately cannot execute it due to syntax error.

Could someone please show me solution?

Do i just need to "modprobe windfarm" and add it to /etc/modules?

Thank you very much for all your help,

very appreciated.

Hello ,

Unfortunately the Fans do Full Spin quite all the time.

Could someone please indicate me a solution?

Fan/Thermal Control

This problem is solved in the latest builds of Debian Etch and will be
sorted by the time Debian 4.0 is released.

Fans will rev to full speed without proper control. This isn't dangerous
to your system - but it sure is annoying! In the meantime,the fan issue
is solved simply through loading up the correct fan modules and forcing
them to load on startup every time. In the terminal:

{{{sudo -s apt-get install powernowd cd /lib/modules/$(uname
-r)/kernel/drivers/macintosh (ls | cut -d. -f1 | xargs -n1 modprobe)
2>/dev/null lsmod | cut -d" " -f1 | grep windfarm >> /etc/modules exit}}}

Done! Fans should slow down immediately and these modules will now load
automatically for you every time you start up your system

Thank you very much,

Ooh... I guess was confused because
https://www.debian.org/ports/powerpc/#ppc64el says "Here you can find
information about the 64-bit PowerPC Little Endian architecture" and
links to https://en.wikipedia.org/wiki/Ppc64 which made it look like
PowerPC 970* was little endian too.

Thanks for the help, now I have the installer going.

    This image will not work on your Macintosh G5, unfortunately.

    Luckily, there is still a way to install Debian on your machine. You
    can download
    a CD image for Debian sid by following the link below:




    Unzipping this file should give you an ISO image which you can burn
    to a CD and use
    to install your G5 with Debian for powerpc. This will give you a
    64-bit kernel (ppc64)
    and a 32-bit userland (powerpc).

    We will be providing full 64-bit ppc64 installation media in the
    future which will
    have both a 64-bit kernel and a 64-bit userland but work on that
    hasn't finished
    yet, unfortunately.
