Supermicro vs No_Drv

TL;DR – A NO_DRV driver is a driver package that doesn’t contain a driver binary. It uses the driver from another package (typically an in-box Microsoft driver).

Server Woes

One of my servers, a SuperMicro 5038A-IL has been locking up on me. I’ve been able to use the machine for the most part for the past year, but the upshot is that I can’t upgrade the machine from one Windows version to another. 22% of the way through WinRE (or sometimes WinPE), the machine has a hard Freeze, and won’t respond to mouse movement or keyboard. I’ve tried kernel debugging, hardware swaps, nothing works. My experience tells me this is a hardware problem. Time to escalate to SuperMicro support.

Upgrade your drivers

OK I should have seen this one coming, I call up support, and the first thing they ask me to do is make sure I have the latest Network and System Drivers.

  1. WinRE doesn’t use Network, so this isn’t a problem.
  2. System Drivers sure! Let’s download and check to see I have the latest stuff.


I open the driver package, and take a look. Wait a minute, I don’t see any *.sys files, only *.inf and *.cat files.

sys – These are the compiled drivers, usually written in c/c++.
inf – These are the install files, typically there is at least one of these.
cat – This is the digial signature, signed by Microsoft to verify the source of the driver.

How can there be no driver in the driver package? Let’s look


Oh, NO_DRV, now I recall, this is an old trick. The device above DEV_191F doesn’t actually require a device driver, it’s transparently handled by Windows. But Windows doesn’t give it a descriptive name, just a generic name. So companies like Intel can provide this pack so you can give some devices more descriptive names in the Device Manager. The intel driver above points to an entry in the machine.inf driver already on the machine.
From:   “PCI Standard ISA bridge”
To:   “Intel(R) C226 Series Server Advanced SKU LPC Controller – 8C56”
That’s all it does, It doesn’t affect the operation of the OS or the hardware. Just the name! Sometimes this is helpful if you need to quickly identify a device, but, yes it’s mostly used for vanity, so I never load them on my machines.
So… I responded to SuperMicro, and confirmed I was using the latest drivers from intel. :^)


Formatting a removable USB drive with 2 partitions

TL;DR – Starting with Windows 10 Insider Preview Build 14965, you can format any “Removable” USB Flash Drive with more than one partition. Perfect for installation of large (over 4GB) WIM files on UEFI machines!


Hey all, back from a week at the Microsoft MVP summit, a Week in the UK, and a week in Arizona.

A few weeks ago at the Microsoft MVP summit, an engineering manager with the Windows Product group made an offhand comment about formatting a removable USB drive with two partitions. This took several of us by surprise, because historically, this hasn’t been supported widely without converting to a Fixed disk or something.

Mike Terrill (and Mike Niehaus) already beat me to the punch with some posts, but I wanted to share my results. :^)

The Background

Why is this important? Well as I mentioned in another blog post, as more and more people are booting to UEFI, on USB flash drives formatted with Fat32, with WIM images over 4GB in size, that causes a problem because Fat32 can’t hold files over 4GB in size.

Another solution would be to use the Rufus tool to split a USB drive into multiple partitions with a hidden fat32 partition. However, the problem here is that the hidden partition uses a special UEFI app that is not signed, so it won’t work on UEFI machines with Secure Boot enabled.

This has become even more interesting since Windows Server 2016 came out, with a base WIM image for standard Server SKU that is over 4GB in size. Hum…

The Hardware


I tested on several different USB makes using my Windows 10 (version 1607) laptop. Some would allow me to create a 2nd partition on a removable Flash Drive, others would not giving me an error:

DISKPART> create part pri

No usable free extent could be found. It may be that there is insufficient 
free space to create a partition at the specified size and offset. Specify
different size and offset values or don't specify either to create the maximum 
sized partition. It may be that the disk is partitioned using the MBR disk
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).

Mostly the older and/or cheaper drives didn’t work, but most of the newer and/or name brand drives did work.

Finally I narrowed it down to two different models, both my favorites:

Then I tested against three Operating Systems: Windows 10 Version 1607, Windows 10 Preview, and Windwos 7.0 SP1. All using Diskpart to create multiple partitions.

The script

Diskpart.exe –>

sel disk 1
create part pri size=450
format quick fs=fat32
create part pri
format quick fs=ntfs

The Results:

                                 SanDisk           Transcend
Windows 7 SP1 Build 7601           Pass               Fail
Windows 10  Version 1607           Pass               Fail
Windows 10 Preview 14965           Pass               Pass   

I was able to format my SanDisk into multiple partitions using Windows 7 and beyond.

But I was not able to format the Transcend drive into multiple partitions using Windows 7 or Windows 10 Version 1607, but I was able to partition into multiple partitions on the new Windows 10 Insider Preview 14965.

That’s new!

I haven’t done enough testing using the removable flash drives on older machines, to see if the partitions are still visible, but the results look promising for a start.

Update #1 – 11/28/16:

Found out today that the reason that my SanDisk Extreme disk worked on Windows 7 and Windows 10 1607 may be because the removable Flash disk is reported as “Fixed” rather than “Removable” to the OS. Link.

Update #2 – 11/28/16:

I noticed that when taking the “removable” disk formatted with 2 partitions from Windows 10 Preview 14965 over to Windows 10 Version 1607, only the first partition was visible. As a work around I tried moving the main NTFS partition first and the Fat32 partition second.

sel disk 1
create part pri
shrink desired=450
format quick fs=ntfs
create part pri
format quick fs=fat32

Install Windows 7 in UEFI

I’m here at the Minnesota Management Summit at the Mall of America.

We got some exciting stuff going on here at 1E around Windows 10 and security features like Secure Boot and Device Guard, and I’ve have been digging into the details of BIOS and UEFI.

The big challenge in this space is helping clients and customers who are currently running Windows 7 to upgrade to Windows 10 with Secure Boot, If you rolled the UEFI firmware back to CSM/BIOS mode, then your machine can’t leverage the super cool Windows 10 In-Place Upgrade functionality to upgrade from Windows 7 to Windows 10. Instead, we will need to perform a wipe and reload on the machine. Stay tuned to 1E for more information this week on BIOS to UEFI.

This all happens when you get a machine that supports UEFI and Secure Boot (Say a machine with a Windows 8, Windows 8.1 or Windows 10 Logo), and you want to install Windows 7. Windows 7 can’t work with UEFI and Secure Boot, because Windows 7 isn’t a supported Secure Boot operating System. Windows 7 does support UEFI, however you may have some more problems getting Windows 7 loading in UEFI, so we may need to add some CSM components, in a “Hybrid Mode” to load. For many IT departments, Getting Windows 7 to load with UEFI is hard, so they load in BIOS mode instead.

Moving forwards, We are now have a new recommendation:

“Install new Computers for Windows 7 in UEFI mode without Secure Boot!” [1] [2]

[1] – May require an updated BIOS

[2] – May require CSM “Hybrid Mode” not full BIOS mode.

The advantage here, is that if/when it becomes necessary to migrate to Windows 10 and leverage the security features of Windows 10, all we need to do is run the standard Windows 10 In-place upgrade task sequence for SCCM/OSD or MDT.  Don’t fall into the CSM/BIOS trap!  :^)

OEM Specific settings

Now, honestly, we have had some problems getting Windows 7 running on a pure “UEFI” implementation, instead we have found out that you must enable *some* legacy aspects of CSM, but not the full CSM mode. We call this “UEFI Hybrid” mode, after the name HP gave this mode (see below).

So how would this look on various machines? Well, we can go into the BIOS and change the settings


  • “LegacyoRom” set to “enable”
  • “ActiveBootList” set to “UEFI”


  • “UEFI/Legacy Boot” set to “Both”
  • “UEFI Priority […]”  = “UEFI First”
  • “CSM Support”  = “YES”


  • “Boot Mode”  = “UEFI Hybrid (with CSM)”

Hopefully this should help you move forwards to Windows 10, yet still deploy Windows 7 for your existing needs.


Fix for Windows 1511 ADK bug

First off, yes, I have a new job working for 1e! I’m super excited, and I should have posted something about it, but I’ve been super busy. My first day on the job was at a customer site in Dallas, and I’ve been on the go ever since, working on this and that (stay tuned :^).

As many of you may have known, there has been a pretty big bug in the Windows 10 Version 1511 ADK, it’s caused all kinds of interop problems with Configuration Manager. Well Microsoft released a fix today! KB3143760. Yea!

Well I opened up KB3143760, and yikes! The instructions are a bit dry. Mount this, patch that, watch out for the data streams!

I needed to patch my local Windows 1511 ADK installation because I’m working on a SCCM+MDT Refresh scenario, and I don’t want to uninstall the 1511 ADK. Perfect timing, if only there was a way to automate this..


Here is a link to a PowerShell script I wrote to auto-magically patch your WinPE files!!158500&authkey=!AHWArN5C7FyRPIY&ithint=file%2cps1

This script will:

  • Download the patch (no need to go through the E-Mail process)
  • Take care of all the stream issues (really I don’t use IE/Edge, so no security streams)
  • Auto extract the patch contents
  • Mount the wim file
  • Patch the appropriate dat files
  • Fix the permissions
  • Dismounts the WIM
  • Cleans up all left over files

So, for example, if you wanted to patch all of the WinPE Wim files in the ADK directory (before importing them into SCCM), you can run the following command:

get-childitem 'C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\*.wim' -recurse | .\Repair-1511ADK.ps1 -verbose

Lately, when programming in PowerShell, I have taken the “write-host considered harmful” rule to heart, so by default, there is *NO* std console output. Instead, I redirect most information output to “verbose”, so if you want to see what is happening in the background, use the -verbose switch.


Hopefully, moving forwards, this will be the *last* time I place a new script up on OneDrive, really I should be moving towards something more… modern… like GitHub.

MDT package now on ready for Windows 10!

Been a while since I posted, I’ve been busy with Surface, Windows 10, and other Kits. But my chocolatey package just got approved, so I thought I would share.

I’ve been following the progress of PowerShell’s OneGet, and for a while now, and thought it was time to stick my toes in and create a package for public use. MDT seemed like a great start.

As you may already know OneGet is a new feature of PowerShell, included in Windows 10 and available through WMF 5.0 that allows for the installation of packages over the internet. Chocolatey is one of the back-end providers, with a great collection of apps ready for installation.

With the recent release of MDT 2013 Update 2, it seemed like a great opportunity to practice my packaging skills. Eventually I created a PowerShell script to auto generate the chocolatey package (not shown here), it would download the MSI files, and extract out the MSI Product Code and Checksum values. You can see the code generated on the Chocolatey MDT page.

Now to install MDT on Windows 10 (or Windows Server 2016), we can run the commands:

set-executionpolicy RemoteSigned; 
Install-Package -Name MDT -ProviderName Chocolatey `
-ForceBootstrap -Force -Verbose

How it works

First step we need to do on clean machine is to set the execution policy:

set-executionpolicy RemoteSigned

Chocolatey has some PowerShell scripts that run in the background, so we need to allow PowerShell to run these commands with the Set-ExecutionPolicy command. Most Powershell users run this command anyways, so it’s not that uncommon.

Then we install the package using the PowerShell 5.0 “Install-Package” cmdlet built into Windows 10:

Install-Package -Name MDT -ProviderName Chocolatey

We must specify the “-ProviderName Chocolatey” parameter the fist time we call Install-Package so the chocolatey Provider is installed, MDT is only known to Chocolatey at this time.

Install-Package will prompt us to confirm installation of the chocolatey provider, we can skip this with the -ForceBootStrap parameter. Additionally, Install-Package will also ask for confirmation before installing MDT, and we can sip the confirmation with the -Force Paramater.

I like to see what is going on the background, so I add the -verbose parameter, and my screen fills with yellow:


We can see Install-Package downloading MicrosoftDeploymentToolkit2013_x64.msi from the Microsoft web servers.


The Windows 10 ADK package has also been uploaded to Chocolatey, but hasn’t been officially approved yet, so when you try to run the “windows-ADK” package it will install the older Windows 8.1 version. We can force the Windows 10 ADK to install with a version parameter. Additionally, the default version of the “Windows-ADK” package does not install USMT, so to install everything we will need the “windows-adk-all” package (which is a lot of stuff, sorry).

install-package -ProviderName Chocolatey -Name Windows-ADK-All `
-force -Verbose -MinimumVersion 10.1.10586.0

MDT UberBug11 – Security vs Usability

(Haven’t posted in a while, been busy with my day job(s), travel, scripting, sleep :^).

Some of you have recently noticed that MDT 2013 Update 1 has changed the way it sets the permissions on the network shares when it creates them for the first time.

When you create a new deployment share in MDT, it will ask you what the network share should be, and the wizard will automatically create the necessary bindings for the share and your local path, including setting up the permissions. Super!


The old permissions used to be “Everyone” has full access, it’s now set to “CREATOR OWNER”. I was somewhat confused by this change, and seemed a bit arbitrary to me. I suspect that someone filed a bug against MDT thinking that locking down the deployment share in the most restrictive way possible would somehow be better, because you know… Security! Think of the security breaches at Home Depot, and Target. PKI. Oh the humanity.

Well, MDT deployment shares don’t really store sensitive information, if you *DO* store any sensitive information on a MDT deployment share, then you are doing it wrong.

But anyways, someone made the decision to lock down the share, although “CREATOR OWNER”, this is kind of confusing to me, only one user? Why not use local “Administrators” group, local administrators already have full access to the files. “CREATOR OWNER” might only give access to one of several local “Administrators”.

Additionally, “Everyone” isn’t really that bad, access files over the network, you are still limited to the “File” level permissions on each file, which are better IMHO, I can create a Logging directory with Create/Write permissions, and set everything else to “Everyone” Read, with “Administrators” “Full R/W”


Anyways, this new permissions change for MDT 2013 Update 1 hasn’t caused much of a problem, as most users can easily work around the issue by adding extra approved users to the share afterwards.


Got a question today about a missing DeployRoot varaiable in BootStrap.ini.

MDT uses BootStrap.ini in WinPE to remember where to find the DeploymentShare to do the heavy lifting.

Normally, when creating a new DeploymentShare, MDT will automatically update the DeployRoot variable in BootStrap.ini, however several users were observing that this was no longer getting updated.

I used my trusty ILSpy to disassemble “C:\Program Files\Microsoft Deployment Toolkit\Bin\Microsoft.BDD.PSSnapIn.dll” and look at the “Provider class”, what I observed is this code segment:

IniManager iniManager = new IniManager(deploymentPointSettings["UNCPath"] + "\\Control\\Bootstrap.ini");
iniManager.Write("Default", "DeployRoot", deploymentPointSettings["UNCPath"]);

You can see here that MDT is attempting to open the Bootstrap.ini file and write the Path to the DeployRoot Value.

Note that MDT is trying to load the Bootstrap.ini file using the same “UNCPath”? I suspected that MDT was failing to open the file due to the restrictive “Creator Owner” permissions, Sure enough, I tried opening the file over the network and it failed. Found!

Work Around

After creating a new deployment share in MDT, be sure to go back and fix some of the defaults:

  • Change the permissions, Something more permissive like local “Adminsitrators”
  • Change the \\server\deploymentshare$\control\bootstrap.ini to include
  • <More to follow I as do more testing>

MDT Bug: 451130 (known issue)


Deployment Gotcha – Get Windows 10 App doesn’t work with MDT

Did you know that you can download *.iso images of Windows 10 using the Get Windows 10 app?

It’s a tool that will allow you to download *.iso images for deployment.

The only problem is that it doesn’t actually download *.iso images, instead, it downloads *.esd images, which are highly compressed *.wim files, that are encrypted/encoded. The tool then decrypts/decodes the *.esd file into *.wim files, and constructs a *.iso image for use.

Additionally, the *.wim file is still a highly compressed *.esd file, so legacy tools that leverage the WIMGAPI library like imagex.exe don’t understand it.  Dism works fine.

That means that you can’t import the images into MDT, because MDT uses the WIMGAPI libarary, and powershell commands might not work either.

I tried to export the *.wim file to another *.wim file, but DISM.exe doesn’t like doing that either.

As a work around you might be able to export the *.wim file to a *.vhd container, and re-capture back to *.wim file with normal compression.

Johan has been documenting esd to wim techniques on his blog.

Otherwise, I hope the DISM team fixes this for TH2 :^) <hint> <hint>
