I bought MSI K9N Ultra MB (nForce 570) AM2, Athlon 64 3500+ (orleans), DDR2-800 (Kingmax 512 MB dimm) but I can't even start installation because "Restart" screen shows after apple logo shows on screen.

In verbose mode (-v) I get something like this:
...
panic(cpu 0 caller 0x001085EE): copy_window_init: cpu > num_cups
Debugger called: <panic>
Backtrace...
...
some hex numbers
...
Backtrace terminated-invalid frame pointer 0x0
Kernel loadable modules in backtrace (with dependencies):
com.apple.driver.AppleACPIPlatform (1.0.3)
depedency: com.apple.iokit.IOPCIFamily(1.9)
depedency: com.apple.iokit.IOACPIFamily (1.2.0)...


Turning off ACPI in bios crushed it even earlier

Thats odd, I have an Asus M2n-SLI Deluxe with the nForce 570 sli chipset and I have performed installs with jas, HotISO and goatse, the standard stuff doesnt work but can be over come. Try reburning it at a slower speed.

I've tried installation from the same dvd on Intel Pentium 4 and it worked fine

Which drive did you install your OSX? My motherboard is nForce 570 SLi chipset too and I can't install OSX on my SATA harddrive. Did you install it to your PATA harddrive?

Yes I have a removable drive cage with the ATA drive noted in my sig with osx on it.

Have the same issue, (same mobo)
Maybe OSX doesn't like MSI K9N

Tried intalling JaS OS X.4.7 on an MSI K9N Platinum (nForce 570, not SLi) with an Athlon 64 3800+ AM2 Socket with SSE3 (Not Athlon 64 X2 3800+) and get the same problem as EasyViber and depeo... However, the DVD did boot on an nForce3 150 with an Athlon 64 3200+ 754 Socket and SSE2.

There seems to be a problem with the MSI nForce570s... That's why I went and got a refund for mine, and got a M2NPV-VM instead. nf4, works with all already.

did you find a PATA driver for nForce570 ?

i had this same problem with my k9N SLI

When you fist boot add the following to the loader

cpus=2

it worked for me

Oh!
I hope you're right. Gonna try right now.

Hello
i'm also having a new system
MB: MSI K9N Ultra (nForce 570)
CPU: AMD X2 4200+ AM2
HD: WD 200B PATA
VGA: ATI Radeon X1600
but when i try to install OSX 10.4.8 Jaas Edition it gived me the same error
i tried more than one DVD but all gives me the same erorr
i hope some one help me to solve this problem
ThanX

Depeo - Did the boot config work?

Abkarino - What error are you getting and what install dvd are you using?

Yes it works like a charm.
I used JaS 10.4.8

I am curious to know what people are getting for xbench results when it comes to disk speeds on an nforce 570 mobo?

i have the msi k9n and i am getting really low disk speeds... anyone run ito this problem or find a solution? maybe a pata driver or something?

hello there guy`s,
i have succseeded booting OSX with the cpus=2 switch and it works fine, but i have problems with the onboard ethernet card and cpu not being recognized as a dual core one...also with the low disk speeds reported by xbench...6 or something..so if anyone has some kind of solution, pls let us know...thanks

p.s. COMPLETE NEWBIE here..

In case anyone comes back to this thread i installed the AppleNforceATA.kext from Medevil and found a huge boost in Xbench.


I am however getting a system freeze quite often, i believe it is caused by forcedeth but i am unsure, can anyone relate or shed any light into the subject?
