budman Posted January 24, 2008 Share Posted January 24, 2008 First off let me say that Kalyway 10.5.1 is my first successful OSX install on a HP nx9420 (with nvidia graphics) after about a year of trying off and on. With some searching I got the network driver installed and things seem pretty stable. QE/CI is working with nv 7900gtx graphics card and I am trying to work out the rest. It seems there is a long standing problem with the audio card, but I can live with out if need be. I do however want to get beth of those cpu cores working. It is an intel t7400 cpu. I started messing around with ACPI kexts, but I thought I would before I really screw something up. Seems a lot of folks live with 1 cpu, so this could be of help to many. Is there any chance? Or am I spinning wheels needlessly? What kernel should I be using? Do I need to patch a kernel? "uname -a" reports: 9.1.0 Darwin Kernel Version 9.1.0: Wed Oct 31 17:46:22 PDT 2007; root:xnu-1228.0.2~1/RELEASE_I386 i386 I installed with mbr efi, currently I have both cores enabled in BIOS, but need to boot with cpus=1 to get to the desktop. Thanks in advance. Link to comment Share on other sites More sharing options...

mtotho Posted January 26, 2008 Share Posted January 26, 2008 I do know there are solutions for cpus=1 for nforce motherboard by replacing the kernel.. but i do not think there is a solution for laptop boards yet. Maybe in 10.5.2 Link to comment Share on other sites More sharing options...

naddy69 Posted January 26, 2008 Share Posted January 26, 2008 Don't feel bad - I've got a Core 2 Quad system that I have to use cpus=1 on! It sucks, but at least everything else works - sound, LAN, all 10 USB ports, Firewire, QE/CI video with Radeon 2600 Pro card. I'm currently running the SSE2 kernel, I even have to use cpus=1 to boot the Kalyway DVD. Without cpus=1 it just reboots after a few seconds. The only good news is that with only 1 CPU running, I guess all 4 megs of cache is available to it! OS X runs very fast! I think it's due to the limited amount of settings in my BIOS - there is no ACPI 2.0 setting, or Plug and Play OS for example. I have tried changing all the settings I do have but nothing helps.
