CRITICAL TECHNICAL CONSIDERATIONS UEFI-only “BIOS” •In order to meet Microsoft’s Windows 8 Connected Standby Logo requirements, the ThinkPad Tablet 2 (TT2) is UEFI-only (no legacy BIOS mode). For more information on this please go HERE •Due to the Clover Trail System-on-a-chip limitations, the TT2 is 32-bit UEFI only. More information on the Intel Atom processor can be found HERE •The only version of WinPE that is UEFI-aware is WinPE 4.0, which is available as part of the Windows 8 ADK Please note, you will need to use the 32-bit version of the WinPE 4.0 code. •The only PXE-bootable solution for imaging the TT2 is to use the Lenovo USB Ethernet Adapter, and again, you will need to then mount a 32-bit WinPE 4.0 boot.wim. •An alternative to that is to create a bootable USB stick containing the 32-bit WinPE 4.0 boot.wim. •By default the TT2 will come set in secure boot mode, and as long as you are using the Microsoft- signed WinPE boot.wim, you will not have any problems. 2 PXE-BOOTING THE TT2 The TT2 supports PXE-booting Upon PXE booting, you will see the via the following: following screen as the TT2 connects with the PXE server: •Must use the Lenovo USB Ethernet adapter. No other devices are supported for PXE booting this device. Upon successful attach to PXE server, you should see: •You may connect the USB Ethernet adapter to the system directly, or via a USB Hub •You may NOT connect the USB Ethernet adapter to the system via the TT2 dock. The dock has a non-PXE Ethernet port which will override the USB adapter. •Once you PXE boot the device, you will need to mount a 32-bit WinPE 4.0 boot wim. And finally, once the boot.wim begins to download, you will see: 3 USB BOOTING THE TT2 1. When you turn on the tablet, press the power button together with the volume up button at the same time to enter the ThinkPad Setup program. 2. On the Boot submenu, select USB Drive, and then tap “+/–” until the USB Drive is shown as the first startup device. 3. Insert the USB key into the USB connector of your tablet. 4. Tap F10 to save the configuration change and exit ThinkPad Setup. The tablet restarts the device will boot from the key. The TT2 can be in the Tablet 2 Dock and boot from the USB ports that are on the dock, or from the USB port on the tablet. Doing so from the dock will allow you to easily connect a keyboard/mouse to the device as well, and once booted, you can utilize the Ethernet port on the dock for network-based imaging (you will need to inject the drivers into your boot media). 4 CREATING USB BOOT MEDIA 1. Open a Command Prompt with Administrator priviliges in either Windows 7 Pro or Windows 8 Pro 2. Insert the target USB boot media device into an available USB port 3. Type DiskPart in the command prompt 4. Type List Disk Make note of the disk number of the target USB drive 5. Type Select Disk X, where X is the target USB drive noted in step 4 6. Type Clean 7. Type Create Partition Primary 8. Type format FS=fat32 quick 9. Type Active 10. Type Assign 11. Type list volume 12. Type Exit At this point copy the entire contents of the desired operating system onto the newly created UEFI boot media device. This can either be a WinPE 4.0 boot.wim, or it can be all of the files necessary to install 32-bit Windows 8 onto the device. This may also be a full SCCM task sequence for deploying a custom image. If you are using anything other than a Microsoft- provided (digitally-signed) OS/boot media, you will need to disable Secure Boot in the UEFI settings, or else the device will not allow the system to boot. Also any boot image you use must be UEFI-aware (i.e. WinPE 4.0). Note, if the AUTORUN.INF file fails to copy from the Windows DVD media to the USB key, then use Notepad to create a new AUTORUN.INF file on the USB boot media. 1. Open the AUTORUN.INF file on the DVD media with Notepad and copy the contents. 2. Create a new file on the USB media with Notepad and paste the contents from step 1 3. Save the file as AUTORUN.INF 5 MICROSOFT IMAGING REQUIREMENTS If you wish to deploy Windows 8 to your TT2 from within the Microsoft framework, only the following versions of the Microsoft toolset are supported: • WDS 2012 • MDT 2012 Update 1 • SCCM 2012 SP1 These releases are the earliest to support Windows 8 deployment. If your deployment infrastructure is not at these release levels, Microsoft recommends that you set up a standalone MDT server and deploy via that means. There are other ways that this can be made to work, but the above are the ONLY supported means. If you wish to have a conversation specific to your environment, please contact your Lenovo FTSS, or your Microsoft Client Solution Specialist.
