gunsu69 Posted May 28, 2012 Share Posted May 28, 2012 Hi All, Have begun the task of installing Lion 10.7.3 on my new Sammy Series 5 Ultrabook. Have previously successfully intalled SL on Lenovo Y510 and Sammy Netbook N120 and have a great ASUS P5kVM unit as well. Thanks for family pack licences of SL! So I have some experience. Am following the ###### on Key method and while getting the ###### boot device selector get the following text when I select the USB key for install: Read HFS+ file: [hd(0,1)/System/Library/CoreServices/Syste.Version.plist 478 bytes. Loading Darwin 10.7 Loading kernel mach_kernel Read HFS+ file: [hd(0,1)/mach_kernel] 4096 bytes. Read HES. file: [hd(0,1)/mach_kernel] 7949336 bytes. Read HES. file: [hd(0,1)/DSDT.aml] 32827 bytes. Using PCI-Root-UID value: 0 ATI Framebuffer Addr: @0xC0000000 MMIO Addr: @0xE0700000 I/O Port Addr: @0x00003000 ROM Addr: @0xFFFE0000 ATI card non-POSTed, reading Video BIOS from PCI ROM @0xfffe0000 Card reported ports: 68 Framebuffer set to:=R At this point it stops either dead or with strange graphic artifacts like half a white screen. So I cant even get to the install stage. I figured the problem may be that the Series 5 has dual graphics cards: HD3000 and a Radeon 7550M. I've tried the GraphicsEnabler=No flag on boot but no use. Also used PCIRootUID=0 and PCIRoot=1 also no use. Have also tried extracting/creating a DSDT.aml using DSDTEditor-Linux-Mac-Win which makes no difference (pictured and used above but same error message without it). UEFI is switched off. The Sammy BIOS doesnt allow me to turn off the Radeon. Any suggestions from anyone? DSDT.aml & dsl attached (also, happy to start/contribute to an install guide on the Samsung Series 5 if we can get it going!)

gunsu69 Posted May 30, 2012 Author Share Posted May 30, 2012 Small update: - Have tried to edit DSDT.AML as per http://www.tonymacx86.com/viewtopic.php?f=170&t=48206 to make sure HD3000 was recognized. No luck though suspect its still the AMD HD7550M that's causing the issue. - Also tried HDMI external monitor. Not detected by the Sammy during boot or after Chameleon launches USB install Link to comment Share on other sites More sharing options...
gunsu69 Posted June 4, 2012 Author Share Posted June 4, 2012 Another small update. I decided to try and create a ###### install for ML DP3 to see if perhaps more graphics cards were supported and successfully created the USB key. I then tried booting with it and found that boot options "-v -x PCIRootUID=0" took me all the way to the install screen! Instead of ATI not-Posted, boot indicated that HD3000 was in use. I then ate lunch and tried to boot into Windows and received several errors (which I didn't write down) but basically complained of "drive error" and wouldn't boot Windows. Several restarts later, Windows came back to life. I then went back and booted from ML DP3 USB key and found the original problem above had returned. I made no changes to the BIOS manually but wonder if a) the ML DP3 installer did and Windows set them back again. This is really odd. I suspect that PCIRootUID flag is a red herring in my case and the issue may be that the BIOS is being changed such that a setting as to which Graphics Card to use is stored there somehow. Unfortunately the Sammy BIOS on this Laptop is extremely dumbed down with no Graphics related options I can see. Hope someone else is fiddling with a Series 5 or can see where the problem is and can shed light on this! Ciao Link to comment Share on other sites More sharing options...
