PookyMacMan Posted November 19, 2011 Share Posted November 19, 2011 Hello! Now my current project is installing SL on a Dell Optiplex 780 with the OSx86 ModCD. Here's my issue: After I boot from the ModCD and swap the DVD, the boot process starts and...that's it. The MAC Framework is initialized and the last thing I get is a declaration of the ACPI System State (well, actually it's the start of the PostbootMOunter, but that's a ModCD thing), both with the vanilla and legacy kernel. I've also tried it with an existing installation, both with vanilla and legacy kernels, and no difference. This computer has an Intel Core 2 Quad with 4 GB of RAM. Should I disable the other three cores? What should I do? Thank you so much.

Gringo Vermelho Posted November 20, 2011 Share Posted November 20, 2011 There is no need to physically remove RAM, just boot with maxmem=2048. Link to comment https://www.insanelymac.com/forum/topic/272400-unknown-boot-problem/#findComment-1772153 Share on other sites More sharing options...
LatinMcG Posted November 21, 2011 Share Posted November 21, 2011 get dsdt.aml into a .zip and post it. (right click compress, then post here) what kexts are u using.

PookyMacMan Posted November 22, 2011 Author Share Posted November 22, 2011 get dsdt.aml into a .zip and post it. (right click compress, then post here)what kexts are u using. (need fakesmc.kext for sure) First of all, the 2 GB RAM didn't work. I am not using a DSDT at all. nawcom compressed the kexts into Extensions.mkext, so I don't know all of them, but I know that fakesmc, ApplePS/2, and NullCPUPowerManagement are a couple (I think he may have a couple ACPI kexts, too, but I'm not sure...)

PookyMacMan Posted November 23, 2011 Author Share Posted November 23, 2011 if u make a usb installer with dsdt and proper smbios.. it might work. mkext tool can show u whats inside I have always found DSDT daunting, but would you be willing to help me learn it? I've also posted something in the DSDT forum about my working system and DSDT... Where can I find mkext tool?

LatinMcG Posted November 23, 2011 Share Posted November 23, 2011 ive learned dsdt trick over yrs, its just some logic of hardware. main thing is learn quirks first rtc, hpet, smbus, wak, pts .. they all have their fixes relevant to how a mac sees dsdt in real mac. mkext tool http://mac.softpedia.com/get/Utilities/MKext-Tool.shtml dump dsdt with linux on cd or usb live http://linux-hybrid-graphics.blogspot.com/ u can skip last step as it only make a .tar.gz file tar czf "${name}.tar.gz" "${name}"/ && ls -l "$( pwd )/${name}".tar.gz and instead zip the folder of the pc model/name to usb or mediafire or post here. what video card is it ? device id? type in linux terminal lspci -v -n Link to comment https://www.insanelymac.com/forum/topic/272400-unknown-boot-problem/#findComment-1773121 Share on other sites More sharing options...
PookyMacMan Posted November 27, 2011 Author Share Posted November 27, 2011 Thank you for your reply. I will check out the DSDT in Linux. My video card is a nVidia Quadro FX 1700 with dev ID 040f; it's supported in NVDANV50HAL.kext.
