Praise the Lord; under AHCI mode the disk partitions properly (and fairly quickly)! Thank you Von1x! A couple of last few questions and we can see light at the end of the tunnel.

To reiterate my current hardware from the first post:
AMD Phenom X3 4580
Asus M2N68-VM motherboard
- Onboard sound: HDeck HD audio (Azalia)
- Onboard networking: nForce PHY Gigabit LAN
-Nvidia nForce 630a chipset
ATi Radeon HD4850 1GB
OCZ Camo Edition 4GB DDR2-1066

This may be of help for reference.

Under video drivers:
I have an ATi HD4850. This is not listed in the driver list under Customize. Seeing that OSX is used on the iMac some of which have 4850s, I assume that 4850 support is built-in and therefor I do not have to select anything under Video Drivers. Can someone verify this for me please?

Under chipset drivers:
I have an nForce chipset (the specific model number I can't recall offhand). The closest option is AppleNForceATA nForce driver, do I check this or the one below which also sounds possible?

Under Ethernet Drivers:
Do I select nForce LAN driver, nForce Ethernet driver, or both?

Under USB Drivers:
Do I select everything?

Under Fixes and Patches:
Do I select everything?

Under Alternate Disablers:
Do I select anything?

Under PS/2 Device Support:
Do I select everything?

Under DSDT Patches:
Do I select everything?

Under Apple SMBIOS Patches:
Do I select everything?


The computer is on and awaiting input. A response as soon as possible will be very much appreciated.
