If I boot without AHCI, then Still waiting for root.... error comes :D
Did you grab Netkas' updated Intel ATA kext? You need to boot in AHCI mode, drop that in S/L/E, and then rebuild your kext cache before finally rebooting and switching to IDE mode.

 

In the case of the Asus boards, we also had to be on what Asus calls "Compatible" IDE mode, rather than Enhanced/Native.

I changed the bios from AHCI to IDE (Compatible Mode) and it seems to be a little better.

BTW I had to install the new Intel ATA Kext mentioned above in post 29.

 

The main problem with this is now I need to change the bios everytime I want to boot to a different OS that is setup in AHCI.

 

I would LOVE to run AHCI on Snow Leopard

Please someone help!!!

I had changed to IDE and the Hard drive is jet near twize as fast (xbench)

 

but i had same problem like the other now i have to change everi time i want Windows to ahci

 

is there really no solution for this ???

Nothing thus far. I've tried everything under the sun that I can think of with no luck. I have a growing suspicion that AHCI link power management isn't being controlled correctly (that is, it only knows to come out of power saving mode when the boot drive is being hit hard) but I have no way to confirm it or fix it.

Hi JN,

I have check your files, and they work OK on my Rampage II.

In order to understand the issue, please send me the following:

1. Your Boot file (boot)

2. The Chamaleon Version you used (RC1, RC2)

3. All your Rampage II BIOS settings

4. Your Memory Type Manufacturer

Here is a link to the boot file.

 

I installed Chameleon-2-1.0-r431.pkg and then install the Chameleon v2 Snow Leopard Support.pkg

 

I think this is RC1

 

Found here: http://www.insanelymac.com/2009/08/how-to-...-pc-hackintosh/

 

 

 

My memory is Corsair Dominator DDR3-1600

 

What bios settings are you interested in knowing about?

 

I am not sure of a good way for me to post them.

 

 

 

Thanks for all your help.

I just installed Leopard 10.5.8 on a Rampage II Extreme system, and I'm seeing the same thing. So it's probably not limited to Snow Leopard.

 

If you want something that will really cook your noodle, run the XBench disk test on your primary drive while doing something to the secondary drive. The secondary drive will suddenly get much, much faster.

 

PS Out of curiosity, what audio drivers are you using for this board?

 

Edit: I'd love to hear how you got SL on that board, too, if you don't mind

 

Same thing here (10.5.8 on a p6t deluxe v2- updated from iatkos 10.5.7 which was the same) tried the x-bench thing- how weird?! I tried switching to ide compatible mode in bios and only 4 of the sata ports are detected, they all show up in ahci but soooo slow it's not worth using. I'd love to hear if anyone finds a solution to this. :thumbsup_anim:

Hi all, disabling the jmicron controller under onboard settings in bios, and then booting in 32bit mode helped alot, but still not perfect. Bootloader chameleon 2 ver r431, with snow leopard boot file support. Use -v -x32 at darwin prompt to boot 32bit. Leads me to believe problem with 64bit drivers or kernel.

But as stated before I do not have this problem at all with Iatkos 10.5.7. upgraded to 10.5.8

Here is a link to my bios screenshots.

 

 

This is how I am running right now.

It runs good on primary SATA but all additional sata drives are painfully slow.

 

Sata1=Western Digital Velociraptor

Sata2=DVD Burner

Sata3=Western Digital Raptor

Sata4=Seagate 500GB drive

 

 

 

 

Forgot the link.

I also want to confirm that I am experiencing the same symptoms as mentioned earlier in the post.

The system will be locked trying to access one of my other sata drives and once I start a safari page it works.

 

It will try to access the sata drive for up to 2 minutes.

But once Safari is loaded of any other application it connects to other sata instantly.

 

Anyone?

I have the same AHCI {censored} bug on my P6T6 WS Revolution, seems all ASUS ICH10 boards have it.

Trying for more then 2 months to fix it with no luck so far, I got it working once or twice with diff settings in BIOS but after reboot bye.

And is not just the slow speed issue, also when OS is on other SATA port then first I got random still waiting for root device.

Someone told me is an IRQ conflict in DSDT but I didn't find it so far(I'm about to learn it byte by byte)... :/

 

@csharpmac if you know what is about just say...is not a BIOS setting so forget about that, I tried all possible combinations, still the bug is present.

 

For those with AD2000b I made a new fix, chek HERE

 

Enjoy!
