Lenovo T400 Laptop

[launchcontrol]

Snow Leopard on a Lenovo T400 laptop (6475-R1U)

 

Some basic hardware specs for those curious what I'm starting with: Intel 5100 wireless, Intel Giga-LAN, Intel Graphics 4500MHD, Conexant HD Smart Audio 221, WebCam (by Sonix/Chicony), Bluetooth, and Ricoh Memory-Card Reader. The following will get some of these working. If anyone know how to get the rest work, much would be appreciated.

 

Step 1 - Preparing

 

Restore a retail copy of Snow Leopard to a 8GB (or higher) external drive (usb memory stick or hd) in an existing OSX system in disk utility

Good guide Step 1 (1-4 only): http://lifehacker.com/5351485/how-to-build...start-to-finish

Run myHack and install to the partition/drive you restored the image to above

Be sure to check the following files: com.apple.Boot.plist and PS2Controller

- Have a USB Keyboard and USB Mouse connected to laptop (the laptop's keyboard and touchpad will not work during installation)

- Connect usb external drive to laptop

- Place BootCD in dvd drive

 

Note: you can try to boot directly from the usb drive, but for me, it would not boot (I get a black screen with a blinking cursor), hence the need for the BootCD.

 

 

Step 2 - Installation

 

Check in BIOS (press F1 on boot up) that under Config > Serial ATA (SATA) > is set to "AHCI"

Boot laptop and press F12 and choose DVD Drive as the boot drive

Once loaded, the BootCD will ask for OSX, point to the usb drive containing the image in step 1

Once in Snow Leopard, go to USB drive and run myHack again, but install to the new OSX drive instead

Reboot (you can remove the disc and unplug the usb drive)

 

 

Step 3 - Installing Kexts (drives)

 

* LAN/Ethernet (Intel 82567LM) (32/64-bit compatible)

Copy kext to your /system/Extensions/

(Note: placing this in your /Extra/Extensions didn't work for me)

 

Download "Intel82566MM.kext.zip" (5th post by dvil)

www.infinitemac.com/f57/intel-ethernet-82566-kext-for-snow-anyone-t3829/

 

[Fully works]

 

 

* Audio (Conexant High Defintion SmartAudio 221)

Delete AppleHDA.kext from /System/Library/Extension

Copy VoodooHDA.kext to /Extra/Extension

Copy Voodoo HDA Helper to Application folder

Run Kext Utility to rebuild kext

Run Repair Permissions in Disk Utilty

Reboot

Run VoodooHDA.prefpane (you can close as your sound now should work)

[speakers, headphones and mic ports work. Internal Mic does not work.]

 

 

* Battery Indicator (32/64-bit compatible)

Copy VoodooBattery.kext to your /Extra/Extensions/

 

Download "VoodooBattery.kext.zip" (Attached file in first post - at bottom)

www.infinitemac.com/f57/guide-4-n00bs-with-laptops-specially-crafted-for-t4183/

 

[Fully works]

 

 

* Utilities > Kext Utility v2.3.2

Run this utility everytime you make kext changes

What doesn't work:

Intel 5100 Wireless

WebCam (in Leopard it worked, but in Snow Leopard is does not. Tried replacing IOUSBFamily.kext and CoreMediaIOServicesPrivate.framework from Leopard but no luck. In fact, w/o IOUSBFamily it says no camera installed)

Bluetooth

Ricoh Memory Card Reader (I tried voodoosdhc, but with no luck)

Finger-Print Reader

 

 

 

Files you need

myHack: http://osx86.sojugarden.com/2009/10/myhack...rc4-1-released/

BootCD by fresch or better, use the BootCD attached that contains the battery indicator kext and presets the screen resolution to the native 1280x800.
