[edit] Kernel Panicking

If your noticing system instability with a Core 2 Duo processor, in the /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file, under Kernel Flags, add 'idlehalt=0'. This will prevent the cores from going into a low-power mode, which has made all the difference running 10.4.8 with Semthex Beta 8 and 9.


[edit] IDE Harddrive

When using a plain IDE hard drive the os will not boot without the install cd in the drive you have to let the bootloader time out and it will boot from the hd then. Mostly a sata board probably wasn't noticed before.


nirvanaguy19: Using uphuck 10.4.9 dvd, installing and using on IDE drive works fine. don't need to keep the install cd in the drive either

[edit] Sleep/Wake

To enable wake with keyboard or mouse, set the PS2_USB_PWR1 jumper to 2-3 (P.20 in the manual, see page 20, item 1 for the jumper location, pin one is the left hand side pin of the three pin row)

In the BIOS enable as AUTO "Suspend to RAM" and enable ANY KEY for "PS2 keyboard Power On"

Sleep works fine under 10.4.9 with teh 8.9.1 Kernel (Ja's 10.4.9 update from Demonoid!)

[edit] Audio

Audio on the Asrock ConRoe945G-DVI can be made to work in at least two ways:
1. For Audio out only:

Delete AppleHDA.kext:

  • In Terminal, type:
  • sudo rm -rf /System/Library/Extensions/AppleHDA.kext
  • sudo rm -rf /System/Library/Extensions.mkext
  • sudo rm -rf /System/Library/Extensions.kextcache

Edit AppleAzaliaAudio.kext:

  • In Terminal, type: sudo pico /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/Info.plist
  • Search for (use hotkey= ctrl + w):
    <key>IOHDAudioCodecVendorID</key>
  • change the string to:
    <string>0x10ec0888</string>
  • Exit pico
  • sudo pico /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist
  • Search for (use hotkey= ctrl + w):
    <key>IOPCIPrimaryMatch</key>
  • change the string to:
    <string>0x27d88086</string>
  • Exit pico

Clean up the system:

  • In Terminal, type:
  • sudo diskutil repairpermissions /
  • sudo kextload /System/Library/Extensions/AppleAzaliaAudio.kext
  • kextcache -k /System/Library/Extensions/

Plug your audio lead into the green rear-panel socket, reboot and enjoy sound out of two channels.

(see forum for original discussion)

2. For Audio in and out (for now) an external device is needed. F.e. the Logitech USB 250 Headset works great after installing SoundBlaster.USB.Audio.Support.pkg drivers from the install cd. They are in the System\Installation\Packages folder 2a. Audio support for the ALC888 in surround is being worked on as we speak: See this article for more information on potentially getting 5.1 or 6.1 sound with Mic and Line in.

[edit] Network

DaemonES has ported the Linux R1000 drivers. Download the drivers packaged with an installer from NeoPheus. The driver announcement is here.

[edit] Integrated video

On a JAS 10.4.6/10.4.7 install, the integrated GMA 950 supports CI and QE when selecting the GMA 900 driver upon installation


gaylord66: For me, choosing the GMA900 Package when installing with Jas 10.4.8. (with semthex's kernel) made the screen on first boot up corrupt with weird blue artifacts, couldn't set up my account, had to reinstall. I fixed it by choosing the nothing except the SSE3 Intel kernel package. Then, when everything was set up and I finally was in OS X, I put the Install disk in and went to System/Installation/Packages and installed the Package "JaS.10.4.8.GMA.950.Support.pkg" manually. After rebooting QE/CI will be enabled and you can choose between all common resolutions.


bart99 I installes 10.4.8 and had no CI/QE after first bootup but a message saying that AppleIntelGMA915.kext could not be loaded. Checking /System/Library/Extensions/ for permissions (with 'ls -la') it turned out the permissions where not set correctly for this and three more GMA915 extensions/plugins. After setting the permissions like they were for all other extensions, 'weird blue artifacts' showed up after reboot. So I booted the install disk, started Utilities/Terminal, removed the GMA915-extensions and rebooted to a system again featuring unaccelerated but at least functioning graphics. As my install disk had no "JaS.10.4.8.GMA.950.Support.pkg", only ""JaS.10.4.8.GMA.900.Support.pkg" and that was the one that got me the non-working extensions, I figured I might try copying all "AppleIntelGMA950*" from a real Mac with Intel GMA 950 graphics. Did so, repaired permissions (owner was wrong after copying) and successfully started the system with CI/QE supported.

[edit] Add on video cards

The Natit device driver works if you have kernel version 8.8.1
