PXE Boot and BIOS Modes

Now you have your new Toshiba 6th generation Core-i (Skylake) series notebook you want to deploy an image and perform compliancy tests. You’ve downloaded the driver package but are failing to get the notebook to PXE boot to your SCCM system.

If you’ve read the previous blog article “BIOS Boot Modes and TPM2.0” you will remember that the notebook is set to UEFI or UEFI Legacy as standard. This means to perform a PXE boot you will need to running SCCM2012 as this will support UEFI PXE booting. If you are running SCCM2007 then PXE booting is not possible unless you set your notebook BIOS to CSM(1) Mode. However, as previously discussed this means that you will not be able to access the TPM2.0 controller which is now standard in our products, which in turn will bring challenges if you are using Bitlocker as no TPM will be available in CSM Mode.

So, what can you do if you do not, or cannot upgrade to SCCM2012 yet, or you cannot use CSM Mode due to needing access to the TPM controller?

The only option you have is to boot from a USB stick…

You can create a USB boot stick that will boot into 64-bit WinPE with the notebook set to UEFI Legacy or UEFI Mode, and from there connect to your SCCM deployment server and start the OS deployment. This will effectively by-pass the need for PXE boot support. To achieve this you will need to ensure your WinPE 64-bit boot stick image contains the WinPE drivers for the AHCI Driver, LAN Driver, TVALZ Driver, and USB3 Driver components. The WinPE drivers are available on our FTP site, an example location would be “/Deployment_Files/Current/A30x-C_A40-C_R30-C_R40-C_Z30x-C_Z40x-C_Z50-C_Series/WinPE Drivers”.

Finally, don’t forget that if you are PXE booting into SCCM2012 you will need to update your boot image to include the WinPE drivers for the AHCI Driver, LAN Driver, TVALZ Driver, and USB3 Driver components.

Until the next time,
