VGA

0. SMBios -> MacBookPro8,1
1. patch DSDT with VGA.txt
2. fix AppleIntelSNBGraphicsFB.kext with hex editor.

Open AppleIntelSNBgraphicsFB in AppleIntelSNBgraphicsFB.kext/Content/MacOS/ with hex editor, then find 0102 0400 1007 0000 1007 0000,it indicates 4 display port of machine(1 for the internal LCD monitor ,the next 4 lines describe the 4 ports), the 1st line is about the internal monitor(0503 0000 0200 0000 3000 0000) the 2nd line is about HDMI port(0205 0000 0004 0000 0700 0000) if you have one. Because G470 has no HDMI port, so replace the 2nd line with 0602 0000 0001 0000 0900 0000, it describes a VGA port. Actually, because Mac has no VGA port, it's obvious that its driver has no infomation about VGA port, this line is copy from other place.

Fix Intel HD3000 memory size (10.11＋ need to disable SIP first; use the backup kext if failed)
