T40 Hackintosh Win7 & OSx Dualboot Install Guide


1 post in this topic

Recommended Posts

I decided to post this tutorial in an effort to help others like myself who were unable to locate one set of detailed instructions on how to successfully load OSx 10.5.6 on a ThinkPad T40. The below instructions are not my own and I do not wish to take credit for someone else's work. I pieced the below together in detail from various sources to aid others wishing to get OSx running on their T40 alongside Win7 in a dualboot environment. My system is completely stable, and everything is currently working, which includes wi-fi after the recent hardware upgrade.


Good Luck and happy computing!




Tools Needed:

- An IBM 2373-W11

- Super F-disk Bootable CD (torrents available, search for them)

- iPC OSx86 10.5.6 PPF5 Final

- Windows 7 (Retail Install Disk)


Step One - BIOS:

- Set BIOS to default settings

- Change the boot order so that the CD-ROM/DVD drive is set as the priority boot device, Primary harddrive is secondary boot device, and USB device as third (doesn't really matter what comes second or third, as long as the priority boot device is the CD-ROM/DVD drive.


Step Two - Super F-disk:

- Load the Super F-disk Bootable CD into your drive and hard reboot your machine (assuming that there is currently no OS installed)

*NOTE: If you have a current OS installed (i.e. Windows), backup all of your necessary files as we will be performing a fresh install of Windows after formatting the drive.

- Super F-disk will load automatically, once loaded click OK on any pop-ups and navigate to the main interface

- Select Operations, and then choose the option to Erase MBR

- Click OK or Yes to any pop-ups

- You should now see one primary partition with a system label of "FREE"

- Close out of Super F-disk, but do not select the option to reboot just yet, first remove your bootable CD and then load your iPC OSx86 10.5.6 PPF5 Final DVD into your DVD-ROM drive

- Reboot your PC


Step Three - Creating and Formatting Partitions:

- When your system boots, press F8 at the boot screen to enter the bootloader

- boot with -f or -v (to see any errors) (I personally booted with -f)

- If booting with -f, your system should quickly flash some text and then switch to the grey signature Apple loading screen (If your system is like mine, this will take a good 10-15 minutes, and it will appear as though your system is hanging, but it isn't. Be patient and continue to wait, and you will eventually come to your language selection.)

- Select your desired language

- At the Welcome screen, select Utilities/Disk Utility

- You should have one drive loaded with no current partitions

- Select your drive on the left

- Select Partition on right, and choose 2 partitions from the drop down under Volume Scheme

- Select the first newly created partition "disk0s1" (Untitled 1) and under Volume Information, enter the following:

- Name: MacOSX (no spaces)

- Format: Mac OS Extended (Journaled)

- Size: Leave as default (OSx will need at least 20GB of space for the install)

- Click "Options" on the bottom, and make sure that the format setting is set to GUID

- Click "Apply"

- Now, select your secondary partition "disk0s2" (Untitled 2) and under Volume Information, enter the following:

- Name: WINDOWS7 (no spaces)

- Format: MS-DOS (FAT)

- Size: Again, leave as default

- Click "Apply"

- After both partitions have been created and formatted, close Disk Utility, and then quit the install and your system should reboot

- While your system is rebooting, remove the iPC install disc and pop in your Windows 7 install disc


Step Four - Install Windows 7:

*NOTE: Now you will install Windows 7 to Partition 3. You'll have to reformat it to NTFS in the Windows 7 installer before Windows will let you install. We labeled it WINDOWS7 in the previous step.

- Wait for Windows to begin the installation process

- Accept the License Agreement

- At "Which type of installation do you want?", select Custom (Advanced)

- At "Where do you want to install Windows?", Disk 0 Partition 3: WINDOWS7

- Click "Drive options (advanced)"

- Click "format"

- Click "OK"

- Click "Next"


At this point Windows 7 will install to Partition 3. The installer will reboot the computer a few times - just leave it until you complete the installation process and see the Windows desktop. Remove the Windows 7 installation disc and pop in your iPC OSx86 10.5.6 PPF5 Final disc and restart your machine.


Step Five - Install Leopard:

- When your machine restarts, press F8 again to enter your bootloader

- At the "boot:" prompt type -f or -v (if you want to see any errors)

- If booting with -f, your system should quickly flash some text and then switch to the grey signature Apple loading screen (Again, this will take a good 10-15 minutes, and it will appear as though your system is hanging, but it isn't. Be patient and continue to wait, and you will eventually come to your language selection.)

- Select your desired language

- Accept and continue past the Terms and Conditions listed by the iPC team

- This time you should see the partition you created in Step Three

- Select the visible partition

- Click Continue

- When you get to the "Install Mac OS X" screen, choose "Customize", and select ONLY the below options:


- iPC OSx86 10.5.6 Base System

- Kernels: 9.5.0 Voodoo Kernel (only)

- Video Drivers: Intel GMA950 (only)

- Audio Drivers: AD1980 (only)

- Ethernet Drivers: Intel PRO 100/VE (only)

- Wifi: IO80211family.kext(10.4) (Will not work but you can update the hardware to a FRU P/N 39T0071 in order to make it work)

- Chipset Drivers: LegacyAppleIntelPIIXATA drivers (only)

- USB Drivers: Patched USB Drivers (only)

- Power Management: All

- Fixes and patched: Seatbelt.kext 10.5.5, PS/2 Keyboard fix, ACPI Fix, CPUS=1 One Core Fix, and Finder 10.5.5 + Keyboard.prefPane

- AppleSMBIOS Patch: ApleSMBIOS ToH

- Alternate Disablers: IntelCPUPMDisabler

- DSDT Patches: Patch DSDT



*NOTE: On the first boot make sure to boot with the -f boot flag! Also, you can later update to 10.5.8 by server and re-load all of your drivers again in safemode: rd=disk0s1



- Click "Save"

- You should be brought back to the install screen, make sure you drive is selected above, and choose "Install"

- The install will first check the drive and then proceed to the installtion. Should take anywhere from 1-1.5 hours to complete.

- Once installed, you will be prompted to restart

- Click "Restart", and wait for the system to completely shut down

- Upon restart, remove the iPC installation disc, and boot into Windows 7


Step Six - Activating OSx Partition (disk0s1):

Wait for Windows 7 to fully load and then begin with the below steps.

- Click "Start"

- In the text field located below "All Programs" type cmd (this will bring up the command prompt for MS-DOS)

- Type: DISKPART, and click YES to the pop-up window

- This will load a new DOS window

- Type: list disk

- Type: select disk 0

- Type: list partition

- Type: select partition 1

- Type: active

- Type: exit

- Type: exit (again in second DOS window)


- Now restart your computer again

- When system boots backup, press F8 to bring up your bootloader screen (you should now see both Windows 7 & OSx as selectable options)

- Type: -f (first boot after OSx install)

- It will appear as though the system is hanging. It isn't. Just give it a couple of minutes to load and then go through your preferences to complete the installation.


You should now have a dualboot (Windows 7 & OSx) ThinkPad T40.


Additional Key Notes:

- It is EXTREMELY important to disable all sleep modes from your recently

completed OSx 10.5.6 installation. Sleep Mode tends to create panics upon

restarts and may prevent from re-entering the
