				Installing SL on Gigabyte EP45-UD3P
			 
			Hi, 
		 
		
		
		
		
		
		
	
	I am trying to install SL on a EP45-UD3P but it KP as soon as I try booting off the SL HD. Has anyone been successful in getting SL to work for them on this particular board? Thanks.  |

		 It's not unique to this board.  There are a few threads discussing KP's and possible fixes.

				UD3P works
			 
			Have you perused Project Snow?   The author uses a EP45T-UD3P and provides detailed instructions on installation. 
		 
		
		
		
		
			I've a EP45-UD3P with a Q6600. SL runs on all of four kexts and a modded DSDT, though I do have issues thanks to my Sapphire 3870. This board, (the UD3P), accommodates SL quite gracefully. q6600 @ 3.6 gHz (In Leopard) (9 x 400) ep45-UD3P ver. 1.0, bios F10e (1.20 ahci) Sapphire 3870 4 gigs 1066 Reaper 8 x WD 250 YD-01NVB1 800w BFG ES Xig S1283 20" $10 Box Fan & a deconstructed P2 case with the side removed.  |

				dsdt
			 
			The author of Project Snow has posted his dsdt on that site, both in .dsl and .aml format.  His audio solution will likely not work OOB for you however.   I think the sound issues from the black jack in back with layout-id "12".  Try layout-id "66" or in hex, "0x42, 0x00, 0x00, 0x00" with the proper codec-id and sound should be fine.  It's worked for everyone else so far. 
		 
		
		
		
		
			Alternatively there is a thread over on Insanely with a .pdf detailing exactly how to mod your dsdt (for the UD3x) for SL. If you speak Spanish, Pere has a expansive DSDT site at osx86.es I don't think my DSDT will help you past the kps.

		 I've updated my signature with my hardware, and now I'm going to do a deep search for my DSDT patching guide in english

			Try koalala's beta 5 tool.  It's in English and should enable your hardware.
