This tutorial is for educational purposes only. You, of course, assume all responsibility for choosing to follow this tutorial. Also, OS X EULA states that you can run Snow Leopard on Apple labeled hardware only.

Bios settings for ga p35-ds3pBios settings for ga p35-ds3p 2Bios settings for ga p35-ds3p 3Bios settings for ga p35-ds3p 4

If you have dual core or quad core processor, you should change HPET Mode to “64-bit mode” so your system will be 64 bit, pentium d users should leave 32-bit Mode.

Press F10 to save and exit.

when line is added, save the file and replace your Library/Preferences/SystemConfiguration/ file with the one on your desktop
