24″ iMac ALSA configuration June 23, 2008

Posted by idebian in Debian, GNU/Linux, Hardware.

Now that the nVIDIA video driver has been set-up let’s give our iMAC a voice (the stereo speakers) and a pair of ears (the stereo mic) 🙂
We will go briefly in the Linux’s ALSA configuration of the integrated iMac sound card.


CPU frequency scaling in Linux June 22, 2008

Posted by idebian in Debian, GNU/Linux, Hardware.

The recent CPUs have a feature which let them scale their operating frequency (changing a voltage power supply input) according to the system/user needs.
This way, when the entire processor resources are not needed, the system can greatly reduces the overall power consumption, lowering temperatures and fan speed 😉

This post addresses the frequency scaling setup in Linux: enjoy 😀


nVIDIA 8800 on Debian June 21, 2008

Posted by idebian in Debian, GNU/Linux, Hardware.

Hi everybody,
The recipe for today is how to properly install and configure nVIDIA driver for my iMac’s 8800GT (G92) on 64 bit Debian Linux 5.0 (lenny).

Even if the driver installation will follow the Debian way, specifically the simplest method with module-assistant, I wish the concepts illustrated here might be useful also for the other Linux distributions: you all guys are more than welcome 🙂


iMac triple-boot (Part 2): OSs installation June 20, 2008

Welcome back Guyz,
if you followed my part 1 guide on how to configure the iMAC for a typical triple boot configuration, we had just repartitioned the HD and installed the rEFIt boot manager.

We can now step on the Linux and Windows operating system installation.


iMac triple-boot (Part 1): The perfect partitioning scheme ;) June 18, 2008

Posted by idebian in Apple, MacOS.

Hi Guyz,
Welcome to my 2 parts guide on how to configure the iMAC for a typical triple boot configuration topped with some little extra goodies.

The system I want shall definitively include:

  1. Mac OS 10.5.3 Leopard
  2. Debian GNU/Linux 5.0 “Lenny” (64 bit)
  3. Windows Vista (32 bit)

In order to achieve this we will go through the following steps:

  1. Repartition the Hard Drive in order to accommodate the other OSs
  2. Install a boot manager (rEFIt)
  3. Install Debian
  4. Install Vista
  5. Finalize the process (clean and minor other stuff).

The first two steps will be covered in this post, while the others will be covered in the upcoming post “iMac triple-boot (Part 2): OSs installation“.


A new ERA… June 16, 2008

I am back online and a new era is going to start …

After spending a couple of months trying to configure the ATI HD2600 under Linux (for 3D and H264 video) … I just gave up.
Sorry for this guys but … I think I will never buy an ATI card again if they don’t fix this situation. ATI’s Linux support really sucks!

Anyway, back in March Apple presented the new iMAC family which spotted a top level machine with the nVidia 8800 GS chipset equipped with 512MB of RAM: that was something I couldn’t miss!!!
On last Saturday I trade my “old” iMAC for such a new “Siluro” (torpedo in Italian) and here we start again with iDebian.
