wws12 Posted January 1, 2013 Share Posted January 1, 2013 Hi. I am trying to install SL with nawcom's ModCd. When I select the DVD in ModCd, it gives me a scrolling list of files being loaded and tells me to press Q to continue. If I do, my computer reboots immediately. Is this because I do not yet have a discrete gfx card installed and are only using the built in HD 2000 gfx? I suspect that, but want to confirm in case it's something else. Thanks for your assistance as always! Link to comment https://www.insanelymac.com/forum/topic/285363-reboot-after-selecting-sl-dvd-in-nawcoms-modcd/ Share on other sites More sharing options...
iWin32 Posted January 1, 2013 Share Posted January 1, 2013 Intel HD Graphics 2000? I'm not 100% sure, but I think that's Sandy Bridge, right? Are you booting from the legacy kernel? You don't have support for it in the Vanilla Kernel until you run a combo update. If it's still rebooting after that, check to see if a custom busratio will work. I know that was the problem on my computer even though it's a first-gen core i3. I hope this helps!

I tried typing mach_kernel at the boot loader but that made no difference. Could you also describe how to enter a custom bus ratio? Thanks for your help!

iWin32 Posted January 1, 2013 Share Posted January 1, 2013 For the mod CD, don't type any specific kernel, and the legacy kernel will be loaded by default. Typing mach_kernel is telling it to use the Vanilla Kernel, hence the reboot. As for the busratio, check out this guide: http://www.insanelym...-your-busratio/ EDIT: Forgot to say, you don't have to modify the Boot.plist, just specify it at boot as a kernel flag like this: busratio=XX. There was a site that listed the proper busratios for the Intel Core i Series (I thought it was netkas), but I can't find it after a google search... outside of a certain onytay. I will never click on his links as long as I live!

I will never click on his links as long as I live! I didn't type any specific kernel at first, that's why I tried mach_kernel when it didn't work. I'll try the bus ratio tip. Do you think it is related to my onboard vgan at all? Edit: by doing the buaratio trick with flags -x and -v., I was able to get much farther loading kexts. However, I still was not able to get to the install screen.

wws12 Posted January 1, 2013 Author Share Posted January 1, 2013 Also forgot to mention that I get some sort of Failed to find boot signature on BIOS device errors. I can't remember if boot or BIOS comes first. It might be BIOS signature on boot device.
