You have to set your disks in the bios to AHCI. Then go into System Preferences and set up Apple software raid.

hello my board does not have an option to AHCI, I'm looking for a way to install on my disk in raid0 or at least a single sata disk, the USB is for testing  . By giving the option to initialize that gives the start time, I can lose data? If you disable the raid and I believe with disk utility information is erased? I'm afraid to try because the disk is almost full, while looking how to install without AHCI mode  |

You can set your disks in the bios to legacy, compatible but you have to use OS X software raid unless you buy a raid card that will work in OS X!

Hey guys this is my first post on here!
So anyways my hackingtosh is feening for my Vertex2 2ssd's to boot raid0.
The guide seems str8 forward i just had a couple of ques.
I followed the tonymac86 guide retail SL dvd, using chameleon 2.30 And i see that my boot.plist is in the root of my osx disk in OSX/Extra/com.apple.Boot.plist..so the file reads like this
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>arch=i386</string>
<key>GraphicsEnabler</key>
<string>No</string>
<key>Timeout</key>
<string>1</string>
<key>Legacy Logo</key>
<string>Yes</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>
1.Do i just insert
<string>boot-uuid=948357DD-2F47-4EE6-8F22-294C275C8A90</string>
underneath <key>Kernel Flags</key>
but with my raid0 identifier correct?
i dont see <key>device-properties</key>
underneath like in the guide?
When i go into sys/lib/sysconfig my boot.plist reads...
<key>Kernel Flags</key>
<string></string>
thats it.
1 other question...
2.When i do this i do this on the target raid0 boot drive correct.
Thanks guys i can't wait to get these runnin in raid0
I appreciate it...-J

I'm just worried that if i try this and something goes wrong i won't be able to boot back into osx with my single boot disc since i will be entering commands in the terminal.
If any does go wrong can i just edit back the com.apple.Boot.plist file and i will be back to normal?
I would really like to do this today if anyone could give me a little push!
Thanks in advance!-J

i cant get this to work i follow the guide to a t.
instead of discs 2&3 im using 1@2 so i change everything correctly.
i first edited the com.apple.Boot.plist in osx/Extra made drive 0 be the #1.saved exited rebooted and i get this error...Loading Darwin/x86
so i tried the plist in lib/pref/sys config and i get the same error?
What am i doing wrong?
Thanks-J

I keep getting "Loading Darwin/x86..." @ end of bios bootup??? So here is the edited plist files (on raid drive) i didn't know if i should edit the plist on raid or current running drive my 1st attempt was Hackingt0sh /Extra/com.apple.boot.plist here.  and this (i just edited both at both locations) This one @ Hackingt0sh/lib/pref/sys config/com.apple.boot.plist (on Raid Drive) here  here is the raid setup in disk utility...I right clicked,got info and copied the Raid Identifier.  here is my terminal session  No matter what i do i get a error at the end of bios bootup it reads... Loading Darwin/x86... Doesn't do anything after that,the bios is set to AHCI,set the #1 drive in the raid to boot. Step 5.might be my problem i dl'd the file extracted to my desktop but did nothing else with these files except leave them on my desktop. Any help would be greatly appreciated i tried to make as easy as possible to understand my steps... -Joey |

Joey, Looks like I have a very similar setup and the steps that you took are exactly the same other than the fact that mine were disk 0 and 1 with the raid volume being set as disk 3. Bootup for me has exactly the same effect, just the darwin line and nothing.. choosing either of the disks yield the same. If I boot from the single disk ( where OSX was installed firstly) and then intercept the boot proces at the chameleon screed (RC5) I have listed the 3 Hdd's If I pick the first HDD in the stripe raid set then it boots form there no problem.
any ideas people... I've not changed anything really form Joeys attempt above... the original install went to a 500 GB disk, with using NON DSDT and EasyBeast with Chameleon RC5 installed..
diskutil list here....

Did you guys remember to have your boot file on your desktop during the session? You only need to modify the com.apple.boot.plist in Extra. Have you tried booting from the other drive in your raid setup by selecting it as boot disk no1 in your bios boot order?

Hey Aquamac, thanks for the reply, So far I've gone a redone the install just incase something got messed up.. or I missed something.. (get to the point where you cant see the wood for the trees!!) I downloaded the chameleon zip files .. placed them on the desktop and ran the commands as per the tutorial... I edit the com.apple.boot.plist file located on the RAID volume. I've tried booting from both drives, by either selecting them at F12 and as directly manipulating the boot order for target 0 or 1 for both the vertex 2 SSD'd. .. Nada However when booting form the single 'master drive' that had the original image installed, chameleon RC5 allows selecting a boot drive of course.... I select one of the RAID drives and voila boots to OSX fine ... go figure...!?! I tried copying the /Extra folder to slice 3 on each of the Raid helper boot partitions namely disk0s3 and disk1s3 nothing there, same stuff, other than the fact that the graphics enabler entry was set to YES (!?!!?) which caused the machine to hang with the usual 100% fan speed on the 5870.. that got changed and still just hang....... I'm getting to the point that I'm going to jump to Hardware raid .. rocket raid etc... as per this chaps successes... www.youtube.com/watch?v=zMOFHAO9AHoI'm happy to progress with this path and any hep muchly appreciated as ever... I could do with a trip back to the UK ...moved to NZ 5 years ago....I'd be able to buy hardware with no problems. Looks like i'm going to have to source the hardware RAID controller if I cant get this to work.... sigh... thanks again for the input... Piers |

as Ive been diggin around to ry and understand the boot process..
Chameleon's boot process requires three essential files. (Listed in simple terms)
boot0 - Install to the drive's MBR - responsible for loading boot1h.
boot1h - Install to the partition's boot-sector - responsible for finding boot.
boot - Install to the partition's root directory - responsible for loading kernel.

anybody ?
another thought .. based on the diskutil list command output above.. are the Rdisk commands valid for my disk listing.. or should those have changed too ?

Hi,
I've been trying to setup an Intel P67 raid-0 array and basically when I booted into OSX it took a s fit and panicked before even loading the OS up. Not only that afterwards my array was corrupted such that I had to start over and turn raid off to boot. One of the drives is now reporting data error in Windows Paragon Partition manager. I presume thats because OSX tried to write to the individual drives and screwed something up. So at this point I don't care if OSX sees my arrays or not though I would like to still have them for Windows as I dual boot from another drive.
I have a couple questions from you experts out there:
1. Was getting an Ebios block error soon after this raid experiment. Turning off raid mode back to ahci and reinstalling my bootloaders and rebuilding the kext caches seemed to have solved that problem. Wondering how that happened?
2. Anyway to get Osx to dual boot and not concern itself with my arrays or at the least boot in raid mode as opposed ahci mode? or even get it to see the arrays without panicking?
Thats about it...
Thanks.
PS: Been googling but only finding bits and pieces.
