[Faisal Aslam 0]

I have HP xw6400 workstation. I have the followig hardware:-

Processor: Core 2 Extreme QX6700 (2.6 Ghz, 4 cores)

Graphic Card: Nvidia Quadro FX 3500M (256 MB GDDR3 256-bit).

RAM: 4 GB DDR2 (will upgrade to 8 GB in a week)

Motherboard Chipset: Intel X38 (Bearlake-X) + ICH9R

Audio: Intel 82801IB ICH9 - High Definition Audio [A2]

High Definition Audio Codec: RealTek ALC262

Network Card: Broadcam BCM5755 NetXtreme Gigabit Ethernet PCI Express

 

I have downloaded OS X Yosemite 10.10.1 and Restore Yosemite.pkg. I don't have any Kexts now and I don't if I have to install it after installing Yosemite or put it in USB before booting from it. I haven't installed Yosemite yet.

Can anyone please suggest me kexts for my hardware? I would be grateful. Also tell me when to install kexts and how. This is my first time hackintosh.
