"ACPI" issue with El Captain.

Hello everyone,

I am new to Hackintosh and I'm currently trying to get El captain on my Dell precision T5500. I've tried using appropriate bootflags but it seem they don't work and keep giving me this panic error saying "unable to find driver for this platform (Error). I did search into many hackintosh community including this subreddit and try following their result but it still doesn't work for me. Right now I'm stumped with this fun project.

My computer Spec:

• Motherboard: Dell Inc. 0D883f
• Cpu: Intel Xeon e5540 @ 2.53Ghz
• Ram: 4 GB
• HD: 1TB

Please let me know if you need more information.
