R700 Trusted Execution Technology - disabling of.
Ok, I'm stumped.
I have a R700 and in the BIOS the 'Trusted Execution Technology option has been enabled.
This seems to mean I can't change my TPM settings amongst other things (nor can I modify VT settings).
It also means I can't update the BIOS with the updated versions.
How can I disable this? I have a feeling it's happened through tiny fingers playing with the laptop to 'see what this button does'.
I've looked to see if there are any instructions for clearing the CMOS, however I may well be in the wrong decade for that being of use.
The laptop is still in warranty, however this doesn't strike me as a warranty issue.
help greatly appreciated,
Mark
the Model is: PT311U
Mark, the model designation and the part number look something like Portege R700-S1321 and PT311U-01800U, respectively. Please give us those.
the toshiba utilities are saying...
Paraphrasing is not helpful. Quote the message precisely - character by character. Better yet, attach a picture.
I can't actually select it in order to disable it.
I don't understand what that means either. What are you looking at? It's grayed out? Again, a picture would help.

Probook 640 bios - Enable Intel VT-x and disable trusted execution for VMWare
With the Probook 640, can someone please explain, step by step, how I would make the proper settings in the bios for VMWare virtualization? I need to enable Intel VT-x and disable trusted execution.Thank you.

There was another setting in bois I found that required scrolling in the bios screen. Tricky to find with no mouse.
I am not sure if some day these terminologies can be standardized so someone can follow very specific instructions rather than vague instructions that are further obfuscated with the use of technical acronyms.
That is the problem, that error message in VM is not explicit enough as to what steps to take to correct the problem. These bois screen authors decide arbitrarily to name settings as it relates to their world personally and there are not standards.
I still don't know how that got changed in the first place but that is not an issue with VM ware as to what else is changing the setting.
Do you have any explicit suggestions as to how the error message can be improved? -
Intel Trusted Execution Engine Interface has a Code 10 error.
When I open Device Manager I get a yellow triangle on the Intel Trusted Execution Engine Interface. I open it and it says
This device cannot start. (Code 10) STATUS_DEVICE_POWER_FAILURE. I have tried uninstalling it and updated all drivers. I don't know what else to do so it will be awesome if anyone can help me out here.You're very welcome.
OK...
Let's try manually installing the driver.
First, go to the Intel TXE driver folder you unzipped and open that folder.
Inside that folder there is another zipped driver folder (KMDF whatever). Unzip that one. Let it extract inside the other folder.
Go to the device manager and click on the problem TXE device.
Then click on the driver tab.
Click on Update Driver.
Select the browse my computer for driver software option and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.
Select Have Disk and browse to: unzipped Intel TXE driver folder\unzipped inner folder\KMDF_NO_RTD3_DRIVER\KMDF_NO_RTD3_DRIVER\NO_RTD3_DRIVER\release\x64\TXEI, and select the Intel(R) Trusted Execution Engine Interface device from the list and see if the driver installs that way. -
Programs hangs, unless highlighting execution or disabling multithreading
I'm making a program to control my signal generator over a GPIB board. Have all the drivers belonging to the SG, so it's just a simple loop where I can set the parameters. VERY basic, I thought....
The program almost immediately hangs... However, when I use 'highlight execution', or 'single step' through it, it runs fine. No problems at all. So that makes it a bit difficult to debug... :-)
Been testing a lot allready and found out that disabling multithreading also solves the problem.
Does that sound familiar? Any way to solve the problem?
I guess it's a timing problem of some sort, but I'm not sure that I can change much. I'm almost only calling the SG driver VI's. Looked into those VI's, and they're all just DLL calls. Nothing I can do there...
Ofcourse I could just disable multithreading as a work-around. But how bad will I suffer in performance/responsiveness if I disable multithreading? It's only a tiny program now, but it's supposed to grow quite big.
Any thoughts?albert geven wrote:
Your problem can be genrated by too fast messaging to the SG
Also polling on a statusbyte should not be too fast, but ms waits should not be neceesary except when polling in a while loop.
Not sure that I understand.. Do you mean that the VI´s that control the SG allready return before the actual instruction is carried out by the instrument? So that I´m issuing new commands while it is not ready with the first ones?
Using sequences to determine execution order is the second best.
Error In, Error out offer better control and more readability.
I know, I know.... But the standard Labview 'wait' VI doesn´t have error I/O. So when I quickly needed to put a wait in a specific spot, I added a sequence around the wait, and run the error line through it. Just now that I had to put in so many, it was becoming a mess. Allready made a custom 'wait' VI with error lines now. (See the code)

Data Execution Prevention - disabling?
I find this DEP option quite annoying, but I can't seem to find where to disable it, if anyone could help me, it would be appreciated.
thnx on advance.Quote
What does it do and what does it stop you from doing?
...IIRC it is a security feature for the buffer overrun type exploit...it may also prevent you from installing legitimate progrqams, Adobe Reader and PSP 8 here, unless you allow an exception or disable it...
...a minor nuisance but nothing to cry over...I wouldn't leave it disabled...
...btw, it's a feature only found on AMD64... -
The Venerable ThinkPad W540 – A Journey in Multiple Parts: Part 2
Missed Part 1? Catch it here
Part 2: System / BIOS setup.
For the average consumer machine, users can get the most out of it without ever having to contemplate these advanced setup procedures. A ThinkPad, however, requires the user to take a peek at them at least, because the default settings certainly do not fit all usage scenarios. From hardware settings, performance and power setup, to security, OS installation and enterprise deployment, almost everything is configurable. Having your ThinkPad wrongly configured in BIOS can slow down OS booting, disabled features you need are not showing up in OS and enabled features you don‘t need will produce unwanted activity / battery drainage etc.
For every ThinkPad I‘ve ever bought, sold or maintained through the years, the BIOS setup is the first thing I ever perform. This is particularly vital today, even before loading up any OS on it, because of the default legacy pre-installed Windows 7 or UEFI BIOS pre-installed Windows 8/8,1 OS, which like in the case of the former, upgrading your Windows 7 pre-installation to Windows 8 instead of clean installing will give you a legacy installed Windows 8 and thus fail to take advantage of some of the UEFI features that are built into the OS. I‘ll get into some of the differences between Legacy/UEFI installations in Part 3 as well as the main only and secondary hard drive dual booting.
NB. Although this setup is for the W540/T540p, most of the options are identical to other ThinkPad models and serve the same function, but being a fully loaded W540, it has several options that other models don‘t have, and thus a perfect machine demonstrate this on.
To enter the ThinkPad UEFI BIOS there are several methods you can use.
Press F1 on the Lenovo screen to bring up the BIOS setup instantly. (Only possible during restart or when started up again from a full shutdown, which you can have your machine enter if you hold down Shift while clicking Shutdown in Windows 8/8.1).
Press Enter on the Lenovo screen, again, only possible using the same restart methods as above, to bring up the Startup Interrupt Menu, and then select F1 for the BIOS setup.
From within Windows 8/8.1:
Open the Charm Bar by pressing Win+C key combination.
Click on Settings
Click on Change PC Settings
Click on General (Win 8) Update and Recovery (Win 8.1)
Scroll to the bottom and click on Advanced Startup -> Restart Now (Win 8) Select Recovery -> Advanced Startup -> Restart Now (Win 8.1)
Click on Troubleshoot
Click on Advanced Options
Click on UEFI Firmware Settings
Click on Restart
NB. By default, a Windows 8/8.1 shutdown is not a real shutdown. Instead, it is hybrid shutdown where contents of memory are saved to disk. This allows for a faster startup. However, turning on the PC after a hybrid shutdown does not allow for pressing F1 or F12 during startup. To disable this behaviour and for further information on booting Windows 8/8.1 pre-installed machines head over to this page: Windows 8/8.1 boot instructions - Lenovo.
If you have a ThinkPad with a Legacy BIOS, just press F1 on the ThinkPad screen.
On the main screen you can see various important information about your ThinkPad such as the serial and MTM numbers, information on your installed CPU and RAM, OS Licence and Secure Boot status. On the image above, I‘ve annotated where you can find the various categories of settings for your machine.
My W540 is setup as non-enterprise, standalone workstation, so the first things I do is turn off AMT (Intel Active Management Technology) and all Wake/Boot from LAN settings, as my machine won‘t be either booted up from LAN nor managed remotely.
To turn these settings off, open up your Config screen and select Network and toggle your preferred settings between Enabled / Disabled. I disable all options. The Intel AMT settings are also found on the Config screen, which I set to disabled. NB, do not select Permanently Disabled if you plan on reselling your machine later on, as permanently disabled means just that.
There are a couple of other features that I disable in the Config section, which is the Intel Smart Connect Technology, which powers on your machine on regular intervals to check for mail and social media updates and the Power – Intel Rapid Start Technology, which I don‘t need on my W-series machines, but I do keep it enabled on my ThinkPad travelmates, such as the T440s.
Walking through the other settings I change on the Config screen, on USB I have everything set to Enabled and USB 3.0 set to Auto. I am particularly fond of the USB always on and Charge in battery mode, as my ThinkPads that have large 9 cell batteries have managed to save my phone from running out of power on countless occasions. Finally, I set my display options for standalone operation, but if you have your machine docked and connected to one or more external monitors, you need to set these accordingly.
On to the Security screen, where many mission critical options reside. Many of these options should not be played with, as setting them wrongly can have serious consequences. Particular care should be taken when setting one or more Passwords for access control, as there is no fallback or fix that can reset a forgotten password.
Leaving the Security settings at their default is fine in most usage scenarios, but some features are disabled by default, like Virtualization, and need to be enabled for them to work. The Security Chip is initially set to Inactive, which means it is visible in your OS, but inactive. I set mine to Active as it is required by the Security Reporting Options, which I do monitor if something comes up as well as enabling the Intel Trusted Execution Technology (TXT) options, which I also have set to Enabled.
The UEFI BIOS Update Option is self-explanatory and in addition you can prevent older BIOS flashing by turning the Secure Rollback Prevention to Enabled. Memory Protection and I/O Port Access are all enabled by default and no restrictions or access control to your hardware is set. The Internal Device Access option is for the Bottom Cover Tamper Protection, which works in conjunction with the Supervisor Password, so if no Supervisor Password is set, the Tamper Protection won‘t take effect even if set to Enabled. The Anti-Theft module is active by default, and thus you‘ll get popups in your Windows OS regarding enrollment. If you do not wish to see those or you won‘t be using the feature, just set the AT Module to Disabled. Same as with the Intel AMT Control, the AT Module can be permanently disabled as well.
Lastly, the Secure Boot option is something that is always enabled by default on all machines that come with a Windows 8/8,1 sticker from manufacturer. Secure boot defines how platform firmware manages security certificates, validation of firmware, and a definition of the interface (protocol) between firmware and the operating system. Secure boot prevents “unauthorized” operating systems and software from loading during the startup process.
Quick summary of the Secure Boot feature:
UEFI allows firmware to implement a security policy.
Secure boot is a UEFI protocol not a Windows 8 feature.
UEFI secure boot is part of Windows 8 secured boot architecture.
Windows 8 utilizes secure boot to ensure that the pre-OS environment is secure.
Secure boot doesn’t “lock out” operating system loaders, but is a policy that allows firmware to validate authenticity of components.
OEMs have the ability to customize their firmware to meet the needs of their customers by customizing the level of certificate and policy management on their platform.
Microsoft does not mandate or control the settings on PC firmware that control or enable secured boot from any operating system other than Windows.
I will go deeper into the Secure Boot settings and functionality in Part 3, where the OS installation will be the topic, but unless you‘re clean installing a new OS or upgrading from Windows 7 to Windows 8, these settings as well as the OS Optimized Default setting on the Restart screen can be left at their defaults.
The Startup section is one that I always clean up and only leave the boot devices I regularly use active on the Boot Priority Order. Don‘t use it? Lose it. This eliminates your machine having to go through all possible boot options on cold boot / restart but a temporary boot device can always be selected through the F12 Boot Menu if you need to boot your machine from a device you don‘t regularly use.
I use my machine as UEFI OS only, as setting it up as dual booted Windows / Linux in UEFI mode has become much simpler, and effective in the last couple of years. However, dual booting a UEFI and a legacy OS, or legacy only is also an option, and will be further discussed in my next instalment.

X131e Virtualization grayed out in BIOS
Hello,
I have purchased my x131e from a retailer here in the United States. I understand the laptop's intended use is for eduction, however, the end user should still have access to most BIOS features.
My issue is as follows - I am unable to change anything in the "Security" menu of the BIOS. There are no locks set on the laptop, although the BIOS requests a password to enter, and I just press "Enter", loading BIOS, accessible almost completely, except for the Security menu. What gives? How do I get full access to my computer?
Thanks,
theinfinitiok, problem solved. Some how the TPM module was stuck in a undefined state. After forcing an enable using the bios configuration utility, and an initialize of the TPM Module from windows (tpm.msc) I needed to reboot and the bios prompted me with the question if I wanted to activate the TPM module. I accepted this and when entering the bios en looking at the system security settings was able to disable Trusted Execution Technology and this gave me the option to enable/disable the virtualization options! Took me 5 hours to get the thing working.

EMET 5.1 crashes all protected applications on Lenovo m91p PCs with enabled VT and TxT
Until last week we successfully used EMET 5.0 on all our PCs.
After upgrading to EMET 5.1 all EMET-protected applications crash
on all our Lenovo m91p PCs when VT-d and TxT is enabled.
The protected applications do not start at all, no balloon-tip or errordialog is shown, only Eventlog shows what happened:

Some facts we figured out:
Tested (crashing) applications for example: Internet Explorer 11, Word 2010, Excel 2010, Firefox 31 ESR, ...
OS is Windows 7 x64 SP1 Enterprise
It doesn't matter if it was an upgrade from EMET 5.0 to EMET 5.1 or reinstalling the PC and doing a fresh install of EMET 5.1 on a fresh machine.
Before Installing EMET 5.1 we used EMET 5.0 on the identically configured Machines (VT + TxT enabled) and there was no problem at all - the Problem is caused by EMET 5.1 and wasn't there with EMET 5.0
Problem disappears if we disable VT in the BIOS of the Lenovo m91p Machines, but this is not a Solution as we depend on using VT for virtualization-purposes.
Lenovo m91p PCs are equipped with: Intel Core i5-2400CPU, 8GB RAM, Onboard-SandyBridge Intel HD Graphics 2000, Mainboard: Lenovo IS6XM Rev.01, Intel Sandy Bridge rev.09, Intel Q67 rev. B3
Other Dell-Notebooks we use (EMET configured identically) don't show this problem, even if VT and TXT is enabled.
Basically we use the EMET Configuration "Popular Software.xml" which is included in the EMET 5.1 MSI Package, additionally we configure
DEP=ApplicationOptOut ASLR=ApplicationOptIn SEHOP=ApplicationOptOut Pinning=Enabled
and enable AdvancedRopSettings DeepHooks=True AntiDetours=True BannedFunctions=True
Additional Information:
TxT (Trusted Execution Technology) is a sub-feature of VT-d in the Bios of the Lenovo m91p PCs, when disabling VT it also disables TxT. We just figured out that we can leave VT turned on but have to disable TxT to get the machines with EMET 5.1 working
again. BUT: It's not an easy solution for us to disable TxT in BIOS on all machines. And as everything worked fine with EMET 5.0 we really think this problem should be solved by an EMET Patch.I'm also experiencing the same issue as the OP, however I'm experiencing this on Lenovo M90p desktops with Windows 7 professional. I was previously running EMET 4.1 and upgraded to 5.1 recently. I cannot reproduce this on a Lenovo M92p with Windows
8.1 Enterprise, nor a Lenovo X1 Carbon with Windows 7 enterprise. -
Virtualization options greyed out in bios hp elite desktop 8300
Hello,

I've tried upgrading to newest bios v2.90 but no sucess, also checked every other bios option, did a full CMOS reset.. but no luck on that either.
Please advise!
Below a photo of the options as shown in the bios. As you can see I only can enable/disable Data Excecution Prevention.
This question was solved.

Processors upgrades to replace the core i3 330m
what processors upgrades to replace the core i3 330m in the hp pavillion dv6-2150us notebook?
This question was solved.
View Solution.Hurray It Worked!!!
I upgraded from an Intel i3-330m @ 2.13ghz to an i520m 2.40ghz w/turbo tech running @ 2.93 max.
now my quest is to try the i7-640m 2.80ghz w/turbo tech that max out at 3.46ghz which will maybe be max cpu upgrade for this laptop. as i stated earlier though the cpu-z stats and the hp manual say the -7-720qm and 820qm will work, they didnt so no chance of a quad core solution for this motherboard and finding another motherboard has been trying. My windows 7 score went from 6.3 up to 6.8 with this cpu upgrade so i can imagine the boost of going to the i7 cpu next. Basicly I feel that this board will only use the Intel Arrandale processor only. so heres the link to the Intel website to view processor comparisons to which you will try for your cpu upgrade. : http://ark.intel.com/compare/47341,43544,49666,50179,43560,47663.

No VPro on 4276-23U? (ThinkPad W520 4276)
Reading the latest tabook.pdf (page 126/174), lists the 4276-23U as the only W520 without vPro.
1) Is this true?
2) What is the impact?
Not all features within vPro (at least as described in the wiki: http://en.wikipedia.org/wiki/Intel_vPro) are important to me, but I will us VMWare on this laptop with full-disk AES encryption, so vPro "certified" may not be important to me, but I hope somone can offer a better understanding of why this particulare Model-Type (4276-23U) lacks this.
Thank you!Well, let me be more specific. If the wiki is correct about vPro, then which of the following does the 4276-23u not have that all other W520's do? (e.g. while I might not care much for remote management either, is that what the 4276-23u lacks, or is it something else from this list that we both care about more?)
... from that wiki....
A vPro PC includes:
Multi-core, multi-threaded Intel Core 2 Duo or Quad processors.[2]
Intel Active Management Technology (Intel AMT), a set of hardware-based features targeted at businesses and which allow remote access to the PC for management and security tasks, when an OS is down or PC power is off.[2][5] Note that AMT is not the same as Intel vPro; AMT is only one element of a vPro PC.
Remote configuration technology for AMT, with certificate-based security. Remote configuration can be performed on “bare-bones” systems, before the OS and/or software management agents are installed.[2][5][9]
Wired and wireless (laptop) network connection.[2]
Intel Trusted Execution Technology (Intel TXT),[2][10][11][12] which is used to verify a launch environment and establish the root of trust, which in turn allows software to build a chain of trust for virtualized environments. Intel TXT also protects secrets during power transitions for both orderly and disorderly shutdowns (a traditionally vulnerable period for security credentials).
Support for IEEE 802.1x, Cisco Self Defending Network (SDN), and Microsoft Network Access Protection (NAP) in laptops, and support for 802.1x and Cisco SDN in desktop PCs.[13][14] Support for these security technologies allows Intel vPro to store the security posture of a PC so that the network can authenticate the system before the OS and applications load, and before the PC is allowed access to the network.[10]
Intel Virtualization Technology, including Intel VT for memory, CPU, and Directed I/O, to support virtualized environments. Intel VT is hardware-based technology, not software-based virtualization. Intel VT lets you run multiple OSs (traditional virtualization) on the same PC or run a specialized or critical application in a separate space—a virtual PC on the physical system—in order to help protect the application or privacy of sensitive information.[3][10][15]
Execute Disable Bit which, when supported by the OS, can help prevent some types of buffer overflow attacks.[16]
Support for Microsoft Windows Vista, including Microsoft Windows Vista BitLocker with an industry-standard Trusted Platform Module version 1.2 and Intel graphics support for Windows Vista AERO graphical user interface.[17][18] -

Does 2 mb cache difference mean a lot in a laptop processor?
Hi
I'm looking at to laptops - one with Intel Core i7-3820QM 2,7 GHz Quad Core & one with Intel Core i7-3720QM 2,6 GHz.
The only difference in the specs acording to Intel comparison chart is this - does the differences have a great significance?
There is a price difference on the two systems, they are build into!
Thanks for any answers

hi guys..
i have a p67a-c45 board and i am about to buy an i5 cpu..... well i dont know which one to buy..
the i5 2500 or i5 2500K???
what the difference???There are a few other differences if you compare the two versions.
2500K: http://ark.intel.com/Product.aspx?id=52210
2500: http://ark.intel.com/Product.aspx?id=52209
The 2500K has Intel® HD Graphics 3000, whereas the 2500 has Intel® HD Graphics 2000. The 2500 benefits from Intel® Trusted Execution Technology and Intel® Virtualization Technology for Directed I/O (VT-d), which the 2500k doesn't support.
