Snow Leopard on X61?

[mfbernstein]

I had Leopard running more or less okay on my X61 (iatkos 5 + updated). I've been trying to install Snow Leopard on the machine now, with a notable lack of success.

Basic problem is that installation goes fine, but when rebooting I get a KP very early in the boot process. I've tried both SnowOSX and a stock 10.6 modified per the instructions at http://www.infinitemac.com/f57/installi ... x61-t3735/ . Oddly the error is the same from both. I'll try capture and post a screenshot, but I was hoping somebody else might have an idea. I've attaching the drive via USB and put it in the drive bay, with the same (unsuccessful) result.

Thanks,

Okay, I found a solution to the kernel panic.

For anyone else curious, the instructions are:
1) Start with the SnowOSX distribution. In the installer, you want to disable LegacyAHCIATA and enable PS2. Otherwise, the defaults should be good.
2) When the install has finished (but before it reboots), open the terminal (Utilities menu -> Terminal) and do
cd /
sh MakeDSDT partitionname

(Where partitionname is the label of the drive you installed to, e.g. "Macintosh HD")
3) Attach a pen drive with copy of the files at http://www.mediafire.com/download.php?uemny2oy3d1 on it. Replace the IOAtaFamily.kext with the one on the pen drive
cd /System/Library/Extensions
mv IOATAFamily.kext IOATAFamily.kextold
mv /Volumes/penddrivename/IOATAFamily.kext .
diskUtil repairPermissions ./
4) Quit terminal and reboot.

WiFi should work out of the box.

For sound, you'll need to get and install VoodooHDA.kext and remove AppleHDA.kext. For ethernet, the SD card reader and battery, you need to install IOSDHCIBlockDevice.kext Intel82566MM.kext and VoodooBattery.kext.

Still working on power management and rebooting (it hangs when put to sleep or rebooted). Suggestions welcome. Thanks.

This is a great start thanks mfbernstein!

I tried installing the Vanilla 10.6 and have been running into PS2 troubles. I can actually get the sucker to load fully into OSX but the mouse is totally dead but the keyboard appears to be showing signs of life. I tried installing the VoodooPS2 drivers and they helped in-as-much as getting me into Single User mode with a working keyboard. OSX still loads up with no mouse support. I'm not sure what I'm missing here. Perhaps there's a higher level apple driver that's killing the voodoo driver. I'll keep poking around with the vanilla for a while and then I'll try the SnowOSX distro you suggested.

Glad to know there's a way to get going quickly!

*Update*

I installed the latest VoodooPS2 drivers with touchpad usign the .pkg method. It dumped all the files into /System/Library/Extensions instead of /Extra/Extensions (which is fine).

I was able to boot up with working mouse and keyboard. In fact even better, the synaptics driver supports multi finger gesturing (2 finger scroll!). Trackpoint unfortunately is not working.

Quick summary of what I got working on my T60p (2007-CQ8):
[*] Atheros Wifi card works OOB
[*] Keyboard/Mouse working with VoodooPS2 kext package
[*] Audio works with removal of AppleHDA.kext and replacement with VoodooHDA.kext
[*] Video works with full CI/QE acceleration with removal of ATISupport.kext, PCI ID entered into ATIRadeonX1000.kext and
addition of ATIinject.kext and ATINDRV.kext with my LCD EDID string embedded.
[*] Battery meter works with VoodooBattery from Superhai
[*] Sleep - unknown as I'm running off my USB drive and when I sleep it goes through the paces but then it shuts doen my USB port (oops) and yeah..
[*] Speedstep - unknown but I suspect it's not working, CPU seems hot

The OS is quite usable in this state. I will be playing with VoodooPower for CPU management.

Once I get some of the other kinks worked out I'll put out my 10.6 Vanilla SL Guide for T60p (2007-CQ8). It will look a lot like my other guides, not too much has changed, except that I can run a Vanilla install of SL which is a nice bonus. This can ONLY be done if you stage your drive in a USB enclosure or you install SL in a different partition first as you need to copy a bunch of kexts over before you do your initial boot.

mfbernstein -
I will try this tomorrow morning. I have been hankering to get Snow Leopard working because Leopard is "behind the times" - all the good Hackintosh tips these days are for SL! I am too lazy and do not have a proper working Leopard install so I don't really want to get a retail disc set up. The iATKOS v7 install was a little problematic for me.

Thanks again! I'll post when it's all set up..

Update - I couldn't get SnowOSX to boot on my X61t. I am ticking with Leopard for now because I hear there's not that much difference and I don't have the time to mess with it right now. (Despite that, I wasted half a weekend on this. I'm just trying to prevent myself wasting the rest of the week for minor improvements.)

Here is a very useful topic:

I just got back into the Thinkpad game again, but I don't quite have it yet so I cannot try it. In any case, it seems like the computer is 100% functioning in 10.5.... it's unclear on whether those extensions work in 10.6, but from the OP's post, it appears they do.
