GA-H87N-WIFI, GA-H87N, HD 4600; Clover Broken after a few boots!
Hi all,
I wondered if anyone was venturing to use Clover to UEFI boot this machine. In my experience, it worked and then it didn't.
Step 1: I succeed in installing 10.9.2 on GA-H87N. Since I'm getting all of the OSes up to date, I also update the BIOS from F2 to F4. I save a backup, but delete it when I don't see anything wrong.
Step 2: A few reboots later, Clover hangs...not during boot-up, but after the cached (or un-cached) drivers are loaded into the kernel. I think it hangs at the resolution-changing bit.
Step 3: I move the drive to a different board, the GA-H87N-WIFI, and Clover boots just fine. I thank my lucky stars noting BIOS F4.
Step 4: I update to BIOS F5, and with the first boot, Clover doesn't load at all. After a reboot, it loads the OS just fine. A couple DSDT edits later, I reboot, and then I get the same issue. Note that if I boot via legacy/CSM mode, I can get into the OS just fine via Clover's boot0af loader.
Step 5: Endless iterations of targeted BIOS, DSDT, and Clover settings. Nothing works. (Back to BIOS F4, then F5 again. Problem remains.)
Step 6: Wait for Clover to be updated or Gigabyte to re-jigger its BIOSes. How could this break in a way that resetting the CMOS couldn't fix? Is there a separate way to reset the NVRAM? (my boot order settings seem to get stored across a clear CMOS, interestingly)
Ideas:
* Intel ME interface is borked because I installed drivers too new for the firmware. (I got a weird error about POST not being reported to ME and the system halting)
* When the Intel VBIOS gets updated, something in Clover doesn't take
* CSM, Clover's CSM driver, and all configurations not involving CSM culminate in a disaster on these new Gigabyte mobos
* Interestingly, I get kernel panics when I patch my DSDT. Ultimately I now neither patch it on-the-fly nor with iASL. Still hoping for HDMI Audio, but clearly I want to be able to boot first.
* I should settle for CSM entry to OS X for now, sadly
