Hi all,

I am sort of stuck. I've built a great hackintosh that I love, and it's been working trouble-free for a month or so now. Tonight, I decided to try connecting an older IDE drive to a Rosewill RAID card that I was using for its two extra SATA ports. The system (during bios) tried detecting the first drive I tried but it couldn't after quite some time trying, but the second drive was detected immediately, then the boot sequence began. But it rebooted immediately when the apple logo/gray screen appeared (it flashed briefly as it rebooted).

In verbose mode, the last lines to appear before the reboot are:

Starting Darwin x86_64
Boot Args: boot-w.....(took a screen shot and it's blurry):

Now, I can't get the system to boot even after removing the SATA RAID card. I tried -F and -x boot flags. I have a Gigabyte DS3H with an i5-2500K. I have tried moving some kexts out of the startup folder and back in, no luck. Now, I am unable to boot from my usb stick (I get an apple with a "no smoking" type circle through it)

Thanks a lot

Yes, I have tried using all the boot flags I know of, plus without any of course. With no flags, or in safe mode, the system begins booting, but as soon as the gray apple logo screen comes on, it immediately reboots (i.e. a quick flash of the apple screen then a black screen due to the reboot).

This is a new problem for me -- the system was working and booting fine until this happened, and I can't figure out what I did to do this, other than test out a SATA card and old hard drive. Otherwise, no hardware was changed. I also tried removing all the components from the motherboard, and resetting the BIOS. I've tried onboard and nvidia graphics, and removed all but one stick of RAM. etc etc. It's super frustrating...thanks for any help.

Specs:

System Hackintosh "Mac Pro 3,1" CPU i5-2500K Graphics GeForce GTS 250 1024 MB Other Hardware Motherboard: Gigabyte Z77-DS3H
Ram: 4 x 4GB Corsair 1600MHz

Try booting with onboard graphics.

Wait a sec
I have the same mobo as you. Given me nothing but trouble until I updated the BIOS.

But first try the onboard graphics

Hi,

I tried updating the bios but I'm already at F9. There wasn't a newer one that wasn't a beta last time I checked.

I tried both graphics (onboard and off)

However, listen to this. I took out the drive, plugged it into my macbook using a usb tool to try to get some stuff off it, including the downloaded mountain lion install so I could make a new ##### stick, then put it back. Lo and behold, it started this time. Something about having it connected to the macbook perhaps? No idea what is going on. I'm afraid to turn it off!

I am sure this is not related to my hardware configuration or motherboard, because it was working so well before. It happened at the same time as I tried putting in a SATA/RAID card with an IDE drive, as funny as that sounds.

I'll try to keep you all updated as I proceed.

Do you have AHCI set instead of IED in your bios?

Hmmm

Have you tried using Clover EFI instead of Chameleon?

No, I haven't tried that. I will research it. Is it supposed to be better than Chameleon, or is just an alternative that you think might work?

Just an alternative

I really have no idea why it is doing that, which is why changing it up to a new boot loader is one of the last things to try.

Its hard to compare Clover with Chameleon. They both have their positives and negatives. I personally like Chameleon because I know it; however, Clover IMO is more powerful overall.

Well, I will definitely try that if it fails to boot after I turn it off. Is it easy to change bootloaders? Is the bootloader responsible for loading all of the things up to the kernel? I always thought the bootloader's role ended as soon as I selected "Mountain Lion" from its menu.

This should answer all your questions concerning what Clover EFI is

Thanks. That looks kind of complicated. I don't know if I would know which choices to make during the installation!
