[edit] General Information

The Asus P5N32-E SLI is a motherboard with an LGA775 socket for Intel® Core™2 Extreme/Core™2 Duo/Pentium® Extreme/Pentium® D/Pentium® 4/Celeron® D Processors Intel® Quad-core CPU Ready. It is based on NVIDIA nForce 680i SLI chipset.

This manual is to help with drivers on Gentoo (or any other linux) for P5N32-E SLI M/B. It should work both for x86 and amd64 systems.

[edit] Kernel configuration

[edit] SATA

Select "NVIDIA SATA support" module.

Linux Kernel Configuration: SATA on P5N32-E SLI 
Device Drivers --->
   Serial ATA (prod) and Parallel ATA (experimental) drivers --->
  <*> NVIDIA SATA support


[edit] Sensors

There are two sensors to get up and running, at least if you have an Intel Core2Duo processor: The coretemp sensors and the motherboard's sensors; for later we will need it87 module.

  • UPDATE* kernel 2.6.22 natively support coretemp module.

As per current kernel (2.6.21) coretemp driver is not supported. There are patches for 2.6.21 (which currently host on private webpage, as I could not find them in a working version anywhere on the net)

To patch your kernel, first make a recursive copy of your current /usr/src/linux directory (i. e. backup your current kernel's sources). Then, copy the patch files into /usr/sources/linux directory, cd to that directory and issue the following commands:

  • sudo patch -p1 -i add-coretemp-driver.patch
  • sudo patch -p1 -i coretemp-add-documentation.patch

You should get messages telling you which files have been (successfully) patched.

Now, enter the menuconfig of your kernel and set the following options:

Linux Kernel Configuration: Sensors on P5B-E with Core2Duo 
Device Drivers --->
 I2C Support --->
  <*> I2C Support
  <*> I2C Device Interface
  Miscellaneous I2C Chip Support --->
   <M> EEPROM reader
 Hardware Monitoring Support --->
  <*> Hardware Monitoring Support
  <M> Intel Core (2) Duo/Solo temperature sensor
  <M> ITE IT87xx and compatibles

Make the kernel and then make sure you load the following modules in /etc/modules.autoload.d/kernel-2.6:

File: /etc/modules.autoload.d/kernel-2.6 
 
  # other modules go here
  eeprom
  coretemp
  it87

[edit] NIC

Note: This is why I decided to write this manual

The NIC is a NVIDIA Dual Gigabit MAC with external Marvell PHY. This chip is in the official kernel sources (2.6.21), but will not work out of the box. Follow these steps:

Enter the menuconfig of your kernel and set the following options:

Linux Kernel Configuration: Sensors on P5B-E with Core2Duo 
Device Drivers --->
    Network device support  ---> 
      [*] Network device support 
          <M>   Dummy net driver support 
         Ethernet (10 or 100Mbit)  --->  (it will work as Gigabit)
   [*] Ethernet (10 or 100Mbit) 
    <M>   nForce Ethernet support
        [*]     Use Rx and Tx Polling (NAPI) (EXPERIMENTAL)

(then enable PHY) 

         PHY device support  --->
   <*> PHY Device support and infrastructure
   <*>   Drivers for Marvell PHYs
File: /etc/modules.autoload.d/kernel-2.6 
 
  # other modules go here
  forcedeth

The module wont work until you do this

File: /etc/modprobe.conf 
 
options forcedeth msi=0 msix=0

After a reboot - the module should be loaded.

Now, for lm_sensors, make sure you have at least version 2.10.2. Emerge them, and as root, run sensors-detect. Now, as a normal user, you should be able to run sensors and you should get the output of the sensors on screen.

[edit] Sound

The soundchip works with the snd-hda-intel sound module. The corresponding kernel options are:

Linux Kernel Configuration: Soundchip on P5N32-E SLI 
Device Drivers --->
 Sound --->
  Advanced Linux Sound Architecture --->
   PCI Devices --->
    <*> Intel HD Audio

Newer kernel versions require you to select the hardware support that you wish to compile as part of the snd-hda-intel driver. The P5N32-E SLI utilizes an Analog Devices AD1988B chip.

Linux Kernel Configuration: Soundchip on P5N32-E SLI - Newer Kernels 
Device Drivers --->
 Sound --->
  Advanced Linux Sound Architecture --->
   PCI Devices --->
    <*> Intel HD Audio
      [*] Build Analog Device HD-audio codec support
