Almost identical rigs - one boots, one won't!
I’m an experienced Hackintosher, and have built several functioning rigs over the last ~7 years thanks to this forum. I have a problem with inconsistent (and occasionally non-existent) booting on a H77N-wifi with a Sandy Bridge cpu.
I have two rigs with same mobo (H77N-wifi, F2 BIOS) but different CPU. Both have worked beautifully in Mtn Lion but I am having trouble in Yosemite.
One rig, "Ivy,” has aIvy Bridge core I3 CPU, 3.0ghz model 3225, CPU id 306a9.
The other rig, “Sandy,” has a Sandy Bridge core I3 CPU, model 2125, CPU id 206A7.
Optimized default settings, no PCI cards, no extra USB devices, and no graphics card. I installed using a Unibeast v5.2 USB stick and the most recent installer from the App Store (10.5.5).
“Ivy” is easy. I can boot easily from the USB I create, install quickly to the HDD, and run multibeast according to the settings below. I get a 98% functional boot drive in about 20 minutes.
“Sandy” is difficult. She will not boot from my Unibeast USB installer—she hangs up after the IO-Bluetooth-whatever message. Because I know that mixed Sandy-Ivy graphics (3000-level GPU with 7-series mobo) are an issue, I used “Ivy” to create a boot disk that would work on "Ivy," then ran Multibeast on it (while still installed in "Ivy") to install the mixed-graphics patch. But that disk only occasionally will boot "Sandy." I even went back to an earlier version of Multibeast to try the same things.
The last thing I see before kernel panic on "Sandy" is: "p state stepper error 18 at step 2 in context 2 on cpu." Crash screen below.
The bizarre thing is that the disk *sometimes* boots. Any ideas? Help!
