No boot with RAID0 enabled

[AndrewNZ]

My sig has my system specs so I won't repeat them.

 

I have Vista booting from an Intel RAID0 array. (This has some kind of driver that boots from the Vista install on the first of the 2 drives allocated to it). It runs fine, very fine in fact. All good so far.

 

I have a 250GB SATA drive (first disk on the SATA bus) that boots into OS X via Chameleon 2.0 (rc1). It runs fine.

 

I have a 500GB SATA Drive that boots into Win7 Beta via Chameleon 2.0 (rc1). It runs fine.

 

The Vista install cannot boot from Chameleon bootloader.

 

Vista will not boot unless the BIOS SATA is set to RAID. (Makes sense since it's a RAID array I suppose). I can boot into Vista with SATA as RAID using F12 to load the BIOS bootloader and selecting the RAID array from there. If I choose anything other than SATA as RAID, Vista will not boot. However, if I select SATA as RAID, Chameleon won't boot.

 

So, to sum up an unavoidably lengthy post, I'd like to boot all three OSes from Chameleon but it doesn't seem to be possible. Can anyone either confirm that I'm wasting my time trying to resolve this little conundrum, or alternatively, does somebody out there know how I can get Chameleon working (And OS X, and Win7 Beta), with Vista as an Intel RAID in my BIOS.

 

(Bolded certain bits for what I hope is clarity)

 

Thanks a bunch for anybody who can shed some light either way.

 

Cheers all.

Andy.

If your trying to use the motherboard's on-board RAID feature your probably not going to have much luck. These On-Board RAIDS are usually still "FAKE" RAIDS in that they pawn all the work on to your CPU instead of doing it itself. Ive gone through the same situation with my mobo. As far as ive seen you have two options for installing to RAID.

 

1. A true RAID controller that does the processing onboard (Expensive)

 

2. Installing to a Soft RAID set up via the Install disk or a second OSX installation. There are a few posted guides here that explain how to set up a soft RAID and then do an install to it. Obviously you couldnt install VISTA to this setup.

 

You would probably be best to install an additional SATA drive and install OSX to it than to.

Hi.

 

My post is probably ambiguous so to clarify (hopefully)...

 

The MB based Intel RAID0 works with Vista. It's fast and hasn't skipped a beat in the couple of years I've been using it. However, if I try to boot via Chameleon with my BIOS set to 'AHCI as RAID', I just get a boot 1 error.

 

If I use 'SATA as AHCI', Chameleon works as advertised and I can boot my non-RAID OS X and Win7 but Vista won't boot. I don't want to boot either OS X or Win7 as RAID - I just want to be able to boot all 3 OSes from Chameleon. I doesn't do that.

 

To sum up, if I have RAID turned on in the BIOS, I can boot Vista but Chameleon doesn't work so I can't boot OS X or Win7.

 

If I have SATA set to AHCI, Chameleon works and I can boot OS X and Win7. But not Vista.

 

if I have SATA set to Disabled, Chameleon works and I can boot OS X and Win7. But not Vista.

 

I think that in loading the RAID driver, it interferes with Chameleon and also OS X & Win7. So none of those will boot yet Vista will.

 

I am stuffed if I know why as AHCI is a component part of Intel's RAID scheme.

 

This is doing my head in. Grrrrrr...

 

(Audible sigh)

 

But thanks for the response anyway.

 

Cheers,

Andy.

Im not too sure then. I do know that if you have your SATA Mode set as AHCI and you install Vista you will only be able to boot Vista in this mode. Changing the Mode to IDE/Legacy or RAID will keep you from booting Vista. A lot of people run into problems in that they are only able to install OSX with the Sata Mode set as IDE/Legacy and in doing so must also reinstall Vista too under this setting for it to work. I know your issue is different but it is vaguely similar.

 

There is a new version of Chameleon coming out but I have not heard of any fixes involving this type of issue. I think its mostly graphical changes. Ill post back if I run across something.

Hi, and thanks for the link.

 

Unfortunately, the solution requires a UUID for the RAID boot partition and Intel's RAID partitioning scheme won't allow the OS to get a valid UUID from it. Weird, in a way, because Disk Utility sees the drives that make up the RAID and the OS throws up an error about the disks being in an unidentified format when the machine first boots into OS X each system start. So the drives are visible to OS X - just not in a partitioning scheme that lets OS X find a UUID.

 

So that pretty much answers my question about whether or not it's possible. Apparently, it's not.

 

I appreciate your input though. And if you stumble across anything else that might be relevant, feel free to add to this thread or PM me a link.

 

Cheers,

Andy.

Yeah I was extremely upset at first as I could not figure out why it wouldn't recognize my RAID. I mean the motherboard sets it up before OSX even boots so I figured it would be transparent. But oh well.
