Will DSDT Fix This?
 

I have a retail installation running. Updated all the way to 10.5.7. The only problem is that I need to boot it with "cpus=1" or it crashes. Would setting up DSDT help to alleviate this problem? Or is there something I forgot to do that's causing this?

On a different partition, I run an installation of iATKOS 5i with the Voodoo kernel installed and I can boot that without "cpus=1" but that's a modified kernel.

My specs are in my signature.

Thanks in advance.

Yes it will. I don't have the patience to dig through all the posts that detail that fix (google cpus=1 dsdt to see them all), but a simpler solution may be to download a fixed bios for your motherboard from http://www.osxcores.site50.net/products.htm

I noticed your motherboard listed in the desktop link:

If you do go this route, all the usual cautions apply: check that the bios is for your exact board, back up your bios, etc.

Also, if it does fix the problem, drop some paypal bucks to them, and please report back to this thread so we know what happens.

Good luck!
