crni Posted March 22, 2006 Share Posted March 22, 2006 Same here with ASUS k8n-sli premium...so I just wait to the 'mach reboot' message and reset computer manually... Link to comment Share on other sites More sharing options...
borez Posted March 24, 2006 Share Posted March 24, 2006 I have the same problem as well. Using Abit KN8 Ultra (nForce 4 Ultra). Link to comment Share on other sites More sharing options...
taek4 Posted March 24, 2006 Share Posted March 24, 2006 Same here. A8N-SLI Deluxe and I think it's the 1016 final BIOS. I can shutdown, but I can't reboot. And sometimes I have got the problem that when I want to boot OSX the Computer hangs on while the circle is rotating, does anyone have similar problems?

c0nfused Posted March 24, 2006 Share Posted March 24, 2006 Same rebooting problem here (DFI Lanparty UT NF4-D) Oddly enough, Windows gives me a wierd pause (mouse can't move) when I'm rebooting it. Anyone else seen that as well? EDIT: I've never had OSX hang on boot for me. There is about a 15 second pause while it is waiting for some driver to respond (you should see it if you run verbose mode), and then it continues booting.

Theios Posted March 24, 2006 Share Posted March 24, 2006 Same here, Gigabyte 8N-SLI-Pro Shutting down is fine, but no hangs on reboot. Link to comment Share on other sites More sharing options...

There is about a 15 second pause while it is waiting for some driver to respond (you should see it if you run verbose mode), and then it continues booting. Strange to say, when I type -v for verbose mode, anything is perfect, it boots perfectly. In verbose mode it never hasn't freezed, only when the apple is shown.. I can't understand it.. Can I tell Darwin that osx should load only with the -v command? Link to comment Share on other sites More sharing options...
Electric Posted March 25, 2006 Share Posted March 25, 2006 Im getting the same thing using a Gigabyte GA-K8NXP-SLi motherboard - does it have something to do with the nForce4 chipset maybe ? Link to comment Share on other sites More sharing options...
blazingarf Posted March 25, 2006 Share Posted March 25, 2006 it probably is the nForce4 chipset.. i have chaintech vnf4 ultra and i get the same error Link to comment Share on other sites More sharing options...

borez Posted March 26, 2006 Share Posted March 26, 2006 If I'm not wrong, when on startup, there is a IOKitWaitQuiet() pause that delays booting by about a few seconds. This is probably due to the SATA controller (from the Nforce SATA thread). Could this have also caused the MACH reboot problem? Link to comment Share on other sites More sharing options...
timmyj Posted March 26, 2006 Share Posted March 26, 2006 there was a fix on the win2osx forums regarding this error for 10.4.3 8F1111. It involved a hex edit of mach_kernel and worked perfectly! However I don't remember it. Link to comment Share on other sites More sharing options...

CFran Posted April 4, 2006 Share Posted April 4, 2006 Same here. ASUS A8N-E. MACH Reboot, then when I press the power button, after 3 seconds it displays "System Doze" and 2 seconds later it switches off. Link to comment Share on other sites More sharing options...
1233666666 Posted April 4, 2006 Share Posted April 4, 2006 Same here on an A8N-E. Must be the nForce chip. Link to comment Share on other sites More sharing options...
barthosch Posted April 19, 2006 Share Posted April 19, 2006 edit: Hi there. my first post :-) Same problems here. A8N-SLI Premium, 10.4.5 Myzar. No shutdown, Reboot seems to work sometimes, sometimes not. HDD Sleep Mode seems to work. Sometimes I can access the Energy Saving preferences, sometimes not. I feel really stupid for buying an nVidia nForce4 SLI chipset (and the A8N-SLI Premium was quite expensive back when I bought mine). Damn, why did I sell my old VIA based system with ATI graphics?? The nForce4 's a great chipset as I understand it (runs superb on Windows). I really really hope some of you guys will come up with a solution (maybe an all-in-one-nForce-installer? ) This is my current MacAMDtoshX86 system so far: AMD Athlon 64 3500: shown as 3,7 GHz but works fine MSI NX6600GT-TD128E (PCIe): Native 1280x1024x32@60Hz resolution with MacVidia drivers (GREAT JOB!) but still waiting for OpenGL/QE/CI though Geforce fan is running at full speed all the time which is quite annoying... SATA: not working, contains my valuable data (work etc.) so I did not put any effort in that because I don't want to loose that data PATA: works Onboard nVidia LAN: works with patched Linux drivers, no problems so far Onboard Marvell Yukon LAN: not working Onboard AC97 sound: not working I did try to add dev-ID and vendor-ID to the kext but it was already in there. Changing PnP-aware OS to enabled/disabled in the BIOS did not help either. System profiler does not see any sound device. Anyone has a hint for me? One strange thing: I had plugged in an old Creative Sound Blaster 16. Sound worked "okay" but the whole system was quite unresponsive - especially Dock animation, Dashboard etc. Maybe some kind of IRQ conflict? Did anyone of you have more success with an nForce4 chipset or even with an A8N-SLI Premium? Hrmm, I maybe should have put this into four or five topics/posts...

Hrmm, I maybe should have put this into four or five topics/posts... my onboard ac97 sound works fine, i have the same motherboard as you (a8n-sli premium) and the same build (myzar 10.4.4) as for the lan, there is a topic for drivers in development here but the driver is still buggy. I haven't tried it myself. Link to comment Share on other sites More sharing options...
caintgetrite Posted May 3, 2006 Share Posted May 3, 2006 Has anyone figured out a solution to the MACH REBOOT freeze yet on the nForce chipset? Hitting the reset button works, but I've been hoping that someone has figured it out by now... Link to comment Share on other sites More sharing options...

superboy Posted May 9, 2006 Share Posted May 9, 2006 Someone said that you can modify the com.apple.Boot.plist,and in the <key>Kernel Flags</key> change it to be <string>platform=X86PC</string>. I don't know if it works for you. Link to comment Share on other sites More sharing options...
