I recently tried my hand at creating a Hackintosh (for research). These are my findings.
I had an old system that I had built some time ago, it was running Windows XP 64, I pretty much stopped using the system when I got my Macbook Pro a little over a year ago. Here are some general specs on the machine:
Motherboard: Biostar NF4ST-A9
CPU: AMD 3400 (2.2 GHz)
Memory: 1GB DDR @ 400MHz (generic)
HD: 250 GB Sata (Seagate)
Video: NVidia 7500 GT 512Mb
Monitors: 2
I succesfully got OSx 10.5.5 Leopard installed and running on the machine with no problems! Everything works great including; sound, dual monitors, ethernet, usb. Pure awesomeness.
First I tweaked the bios to make sure that AHCI was enabled. Easy.
Then I popped the OSX DVD in and let it start up in install mode. Easy again. (I used an (ahem) copy of OSx of the iDeneb flavor that didn’t require any previous patching or tweaking)
Once in the installer, I just selected the options that suited my system and let it rip.
After an hour, the install completed.
The only hickup here was that I had to reset the admin password and then log in as root and create a user account.
