PXI first use, unable to configure/boot safe mode or RT

Hi all,
I am new to PXI controllers, i am having a few issues with a PXI controller in my university which i intend to use for my fyp project.
So we are using a PXI 1042Q chassis with a PXI 8106 embedded controller.
We started this controller for the first time and updated windows xp, we also removed labview 8.6 that came with it and installed labview 2010 with all the available drivers, softwares and liscenses..
When we start windows XP on the PXI system we can see the PXI chassis and controller identified in MAX but labview cannot find them when creating a project.. My first question concerns the reason why labview cannot identify PXI targets in a project?, could it be a missing liscence (for instance RT liscence for PXI)? or an improperly installed driver? How to check if RT liscence is missing or needed?
Due to the first problem, we tried to control the PXI remotelty from another desktop host PC where we found more problems.
1/ Can we make a connection in order to download a project from the host PC to the PXI via ETHERNET (without MXI cards) ?
2/ We tried to make the connection using ethernet but we couldnt configure the IP; when we switch to safe mode to configure, the pxi gives the following texts on screen " system error kernel 446610 LFS error not a dos disk pc-dskinit " and the system remains unconfigured with the 0.0.0.0 IP due to the failure to boot, MAX on the host PC sees the PXI as a 0.0.0.0 and changing the IP is not possible also.
To cure this issue and help the system boot, we created a desktop PC utility USB Drive in MAX (on the host PC), configured the boot devices priority on PXI and booted the PXI from the USB drive. we entered safe mode and the pxi took an IP automatically and then it displayed that the software is not present... The problem is that when we tried to install the software on the pxi using MAX on the host PC (which now sees the PXI) we got disconnected..
Note that firewall is off, the host pc has an ip in range with the one generated by the pxi, on the same subnet and has windows 7..So why are we loosing the connection in MAX after 30 seconds,, when we try to install the software on the pxi?
thank you in advance for your help.

Dear Elias579,
Welcome you to the NI Forums!
There are basically three ways a PXI system can by characterised by the OS:
Real-Time OS running on the PXI makes it an RT Target, which then can be reached from the network by a host PC for example
"regular" Windows running on the PXI makes it a simple industrial PC, which has no real-time qualities. In this case you cannot add the controller to your project, since you are actually on the target, and whatever VIs you crate are actually on the platform already!
Hybrid systems (not all controllers are compatible with this) can run in such a way that one core runs regular Windows and an other runs an RT OS, which can communicate with each other.
Your problem is either
1.) You installed a simple windows, in which case you wont add any targets to your project since you are running every VIs on the target. The chassis works exactly like a PCIe bus slot extender, so the cards inside are the ones that matter. For example if you have a programmable FPGA PXI card, and you have LABVIEW REAL-TIME and NI-RIO driver installed, you will be able to add the card within the chassis to your project.
2.) You are just missing a driver. Since you do not have an RT OS on the PXI, you might need a suitable DAQmx for you cards.
Please to help me have more vision of your problem try to describe what cards are you using and what is actually you would like to do.
For debugging you issue, these documents might help:

https://decibel.ni.com/content/docs/DOC-16189
**EDIT:
one more thing, if you are using a regular Windows PXI, you should not seek to connect to it as an RT Target. You might try to use Remote Desktop from an another PC though.
Looking forwards to help you solve your issue,

Good luck & happy computing!

My Macbook Pro keeps freezing/crashing after a few seconds of use, but works fine in safe mode.

I've researched this extensively, but I haven't been able to solve my problem yet.
It started completely out of the blue with a kernel panic, where my screen seemed to malfunction and I got the kernel panic message (but I could hardly read it because of distorted graphics). I forced my laptop to shut down, but every time I rebooted and used it again it would completely freeze after a while (the amount of time varied, it has lasted from a few seconds to a couple of hours). What happens essentially is that the cursor and entire OS freezes, and I'm unable to click on anything or use the keyboard. The fans start working full speed and the only thing I can do is force the laptop to shut down.
At first I thought it was a Chrome problem because it only happened after I opened the browser. After uninstalling it, the laptop seemed to work fine for a couple of hours, but then it froze again while I was using Safari. Ever since it has been functioning normally for smaller and smaller time periods before freezing again. I've tried reinstalling Snow Leopard OS from the original disc and then downloading all software updates, but the problem continues. I've also tried doing a hardware test by pressing D as the computer starts up, but for some reason it doesn't work.
The laptop, including Chrome and Safari, works fine in safe mode.
I'm sorry I don't know what specific information to give you about my laptop/OS, but please ask anything you need to know. I'd greatly appreciate any help — I'm panicking because I fly to England tomorrow morning to start university and I really don't want to go without a laptop for 2 weeks while it's getting fixed!

Thanks for your reply! Here are the Etrecheck results.

Toshiba Satellite Laptop - Will Not Boot, Safe Mode Not Accessible

Hi everyone, thanks in advance for your help.
I am trying to help my mother-in-law (I know, who does that!?) with her laptop. Because of the boot problems, I can only offer you limited info on the specs, but here is what I do know.
Toshiba Satellite
Model Number PSAE6C-TJ908C
2 Gig RAM (assuming DDR2)
HDD is a Toshiba MK2035GSS 200Gig
OS Windows Vista
Bios Version 2.60
Problem:
First it would boot ok in one user account, but when booted in secondary account it would act odd, ie caps lock stayed on when not pressed, etc. Deleted secondary account, ran Windows repair function, now I cannot access the primary account, will not boot in safe mode, can not change boot sequence in setup to boot from cd or run restore disc. I have to use an external keyboard as the laptop keyboards enter key and "a" keys do not work. (New keyboard which was replaced in December, warranty has since run out, thank you Staples.)
Any and all help greatly appreciated. I'll answer any other questions you have as they come up, I realize I may have left out some key details.
I forgot to add a couple of details. When booting, it hangs at the Toshiba screen prompting for either F2 for setup or F12 for boot device selection, when you reach the log in screen it gives a number of odd sounding beeps (3 I believe), the Filter Keys box comes up, and when you try to enter the login password it will not recognize it.

Satellite A200-TJ (9PSAE6C-TJ908C)

That's one sick laptop. If the thing beeps on startup and even the keyboard doesn't work, I'd figure on replacing it.
Are there important files you need to rescue?

Imac 2011 27" won't boot / safe mode / install disc / bootcamp

I've been having an ongoing problem with my computerwhere it randomly crashes. my first visit with the Apple Store resulted in a replacement of the video card. that only fixed the issue for less than a month. during the second visit they did a full hardware test and deduced that the third party RAM was defective.I was also advised that the OS would need to be reinstalled. when I got the computer back I was able to boot up the system without issues, but before I could back anything up it crashed again. Now I cannot restart the computer past the spinning wheel I get a white screen. I cannot boot the computer into safe mode either. I have the original installation disk but it also hangs after the spinning wheel. I have also tried loading up boot camp and that also hangs after the Windows screen. I was however able to load up Windows in Safe Mode. does anyone know what is going on here?

Try restarting while holding down the Option key. Theoretically, that will prompt the Startup Manager window where you can select the startup disk. If the startup disk is not available, then it's probably time for another trip to the Apple Store.
Did you by chance purchase AppleCare ??

MacBook no boot safe mode help

Please excuse me as I am writing this on my iPhone.
I would love to know if there is anything I can do to get my MacBook to reboot, here is what happened.
It was at the very max of HDD capacity
I was doing too much and the wheel was spinning more and more
I opted to force a power down when I fet it was safe and after that it will not boot
I can use safe mode, cannot repair the drive
I went to a local computer store and was able to boot from a USB, but Disk Utility could not repair the volume
I am away from home on business so I do not have access to any external drives or other recovery software
Is there anything else I can try to do from Safe Mode?
TIA
HENRY

You need to have a minimum of 10% of the hard drive's capacity as free space. Bad things can happen when the free space drops down as low as yours. If the drive's directory is sufficiently corrupted even deleting files may not help. This would seem to be your problem since you could not repair the disk using Disk Utility from the USB drive. And, you cannot repair the disk if you are using it as the startup volume.
It would be more helpful to tell us what model MBP you are using, hard drive capacity and type (HDD or SSD), and version of OS X currently installed.

Booting safe mode hangs during fsck_hfs rMBP + 10.8.0

When trying to boot in safe mode (holding down shift while power on) to troubleshoot issues with the upgrade to 10.8.1 the boot process hangs indefinitely.
When switching on verbose and safe mode (nvram boot-args="-x -v") I see that it proceeds until fsck_hfs is run.
The last message from fsck is: "** check catalog"
There is another message probably unrelated after this:
AppleUSBMultitouchDriver: check state - receive state packet payload 2, device was reinitialized.
After this it hangs (waited for hours).
Already did a internet recovery install of the OS and nothing changed.
Normal booting and recovery system booting works without problems.
When I Verify-Disk in Disk-Utility everything is fine.
Can't upgrade to 10.8.1 because there is also problem with the App Store ugrade (doesn't show upgrades)

Bdobs wrote:
No, my problem started while I was trying to upgrade to 10.8.1. After it rebooted following the update, it would not boot back up. I think I am going to have to restore from my backup (out of town right now).
Thats bad, so it looks like in order to update it starts in safe mode, if safe mode doesn't work it can't update anymore!

Unable to restart from safe mode

Problem: after running in 'Safe Mode', I restarted and it won't boot.
I push power button, and screen comes on with startup tone, then grey apple logo shows up, and a few seconds later, spinning wheel, but a progress bar is below it, and after a few seconds, wheel stops spinning, and screen goes to black and machine shuts down.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

My firefox is running in "safe mode" after i downloaded it - why? how do i take it out of safe mode

I have windows 7 operating system - I just downloaded firefox but it is running in "safe mode" rather than normal mode can you teach me how to fix this please?
== This happened ==
Every time Firefox opened
== I downloaded it and first used it

Do you get the [[Safe mode]] start window?
See [[Firefox is stuck in Safe Mode]]
If you do not get the Safe mode start window then see this article for some suggestions: [[Firefox has just updated tab shows each time you start Firefox]]

PXI-8187 alwayes boot RT in safe mode

Trying to boot RT on PXI-8187 controller with original setup, what ever RT boot selection is used either hardware switch or BIOS RT boot option, the terminal will show the following:
Unable to load LabVIEW RT from drive!
Booting safe mode from ROM...
mount: Mounting /dev/Ma1 on /home/ftp/c failed: Invalid argument
Entering safe mode.
IP address is: 0.0.0.0
Of course after that you can't do any thing to configure the RT target from the MAX on the host computer.
Please Help.

Thanks,
The initial was NTFS but it has evolved:
I used the recovery CD to change the file system to NTFS, it took a while and it installed windows XP from scratch differently from FirstWare that ghosts it (I think). And it didn't install any NI stuff what so ever.
At the end I got the same result as with using the remote system format disk option.
i.e. The RT controller boots in safe mode displaying the previous message without the mount error but this time I can configure the IP address.
Still I can't install software to it, I get the list of features to install, I select them and press next, then I get a dialog saying:
Cannot process install because other dependencies are required:
LabVIEW RT 1.0.1
LabVIEW RT 6.0.1
LabVIEW RT 6.1.0
LabVIEW RT 7.0.0
LabVIEW RT 7.1
Is this a host or RT Controller issue now?
What's next? Thanks for the help

My Mac Book Pro (2010 - Snow Leopard) won't boot, or boot from safe mode.

Hi, a bit of back ground knowledge bout the situation first, I was visiting home to see my family for two weeks in the UK, as i am currently on an internship in Dubai.
A few days ago (one day before i flew back to Dubai from the UK - Thursday 10/07/2014) I noticed out of the blue that my Mac book Pro (i believe early/mid 2010 model) suddenly started running extremely slow. (prior to this I had be using it fine, using an array of programs like Safari & Photoshop that i know usually slows down the Mac, but unlike what I would usually experience, this was pretty much a complete freeze for 5 minutes at a time every time i tried moving my mouse/closing a program or even clicking on something. I decided I would close everything and give the computer a rest. This took a long long time, I had to force quit many of the programs open, then once going to the drop down menu to shut down the laptop it wouldn't shut down. So after a long time of waiting to shut down I decided to force it to shut down by holding down the power button.
I left it for the evening, and then decided to turn on the laptop so it was 'on and working' for my flight back to Dubai as there had been 'stricter airport measures introduced in the UK for flights abroad' and there was a rumor that you had to prove that all electrical devices can be turned on when and if asked by airport security. after a long time it finally turned on and loaded the home screen, it had a long period on the grey apple screen with the turning gear. However still when turned on the problem of being extremely slow - freezing for 5 minutes every time i would click a program or something on the mac, like the drop down menu with the shut down option for example - still persisted. As I had to fly home the next morning (Friday 11/07/2014) I just closed the laptop lid like i had down thousands of times before over the past 3-4 years, packed it in my hand luggage and and went to bed. I flew back to Dubai.
Over the next few days (Saturday 11/07/2014 - Monday 14/07/2014) I used the laptop sparingly a it was super slow, but i did manage to watch the second half of the world cup runners up match between Holland & Brasil. I then went on to attempt to use the safari the on the Monday night, but it was too slow to really do anything, e.g. i couldn't even really look at the BBC website as it was too painfully slow!
This is when I decided to look up why it may be working so slow via my iphone.
So I shut it down,
I looked on forums and support ages and first thing they recommended was a 'safe mode boot up', so I decided to boot up in safe mode. This is where the problem seems to worsen. The Mac book pro would turn on to the grey apple screen and the progress bar appears, it begins to fill up but then reaches perhaps 20-30% then suddenly the laptops fan seems to go into over drive, making lots of noise when before this moment as it tried to boot up it was silent, then it just turns off.
I decided to retry booting up without holding down shift (safe boot mode), but it returns to the grey apple screen with the progress bar again, as if it was in safe mode even though I had held down shift. The same problem happens, its silent as the bar fills until abut 20-30% then it seems to 'overheat' and then turn off again.
I tried to boot it up again and again, both 'normally' without holding down shift, and 'safe mode', but the same issue arises.
So i turned to the forums and help pages again, and there was a mention of a PRAM reset. So i tried booting it up this time but holding down 'CMD + ALT + P + R' on the moment of the first chime, then as normal with a PRAM reset it chimed twice more before I let go of the keyboard. The progress bar again appeared on the grey start up apple page, and this time reached roughly the same 20-30% mark, but without overheating or making a fan noise, it then seemed to restart the progress bar a second time. This time as it reached the 20-30% it would again over heat and then instantly turn off.
I then decided to do a Hardware test. So i turned on the power and held down 'D', this successfully brought up the Hardware testing window, I did a regular test and within a few minutes it said there was no hard ware issue. Not convinced i decided to do an detailed/advanced hardware test which took alot longer. This time after a few minutes it started to make fan noises and 'overheating noises' however completed the hardware test and again said there was no hardware problems. I opted for the 'shut down' option on the screen instead of 'restart'.
I then decided to try and boot it up normally again, and the progress bar appears on the grey apple start up screen, it again reaches 20-30% then turns off.
I've exhausted my knowledge of what to do, and all the forums seem not to give the answer i'm looking for. It sees like no one has had the EXACT same problem i'm experiencing. Also being in Dubai for a further 7 weeks, I can't take the Mac book pro to an apple store, and I do not have any of the install DVD discs ect with me to try booting from DVD disc install.
Does anyone have any suggestions for me on what I could try next? I'd be hugely grateful! Please reply below or email me.

Firefox is crashing continuously when I open it. I'm unable to open it in safe mode and reinstalling the application has not worked.

I've been running Firefox v. 18.0.2 and for a few days the application continually crashes everytime I open it. I'm currently unable to get into safe mode and this is occurring on all profiles on the machine. I've went through and updated all my Add-Ons however the issue persists. I decided to re-install the application wiping out any configurations that were previously configured. I've also tried deleting the entire %APPDATA%\Mozilla folder. Up until this point I am unable to get Firefox running.

1. Click the Windows Start button, and select Run... on Windows XP or press Windows Key + R on Windows Vista/7. Type in "%APPDATA%\Mozilla\Firefox\Crash Reports\submitted" including the quotation marks and click OK.
2. In the resulting folder will be a text file for each crash report you have submitted. Using the View menu, arrange them by date to find out which is the newest file; and double-click on it to open it.
3. Report back to us with the latest crash ids.

POSReady7x32 F8 Safe mode boot

I have just done a clean install of PoSReady7 32 bit.
No additional drivers or Windows updates installed.
OS boots to desktop ok.
However, when I press F8 and select a safe mode boot option, the OS boots as far as the Welcome screen with the animated circle. At this point it reboots! No error message displayed.
Does the same reboot when I use MSCONFIG to force a safe mode boot.
When I use MSCONFIG to force safe mode boot and also select F8 boot option 'Last known good configuration' then OS boots into safe mode ok.
Anyone got any ideas as to why I cannot get into safe mode by just selecting it from F8 boot menu?

Thanks for the suggestion.
The usual Windows boot menu is already being displayed ok when F8 is pressed before Windows OS starts loading.
Anyway, I entered 'bcdedit /set {bootmgr} displaybootmenu yes' which completed successfully but it hasn't stopped the OS from rebooting when I use the F8 safe boot option.

Macbook Pro 15" will only boot up in Safe Mode - Please help!

My Macbook Pro will not boot up normally. It goes past the screen with the apple and the wheel and then just stays white. Also on the screen there are little rectangular blocks going across diagonally. In Safe Mode, it boots up but with little square blocks going across the screen. Can anyone help please?

Firstly, see this article: Mac OS X- What is Safe Boot, Safe Mode? and this one: Gray screen appears during startup.
Secondly, try the following:
Delete caches to resolve some startup problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
/sbin/fsck -fy
If you receive a message that says "***** FILE SYSTEM WAS MODIFIED *****" then re-run the command until you receive a message that says "** The volume (name_of_volume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /Library/Caches/*
reboot
I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-user mode you have 'root' access, so it's important that you not make any mistakes.
Lastly, reinstall Snow Leopard if the above doesn't help. This will not erase the drive.

How do I fix this? "Firefox is unable to start correctly (0xc0000056)" I can't start in Safe Mode, either.

My Firefox does not open, at all. When I try to open i get the message that says "Firefox is unable to start correctly (0xc0000056)". I have tried to run the Firefox crash report, which also does not run. I'm unable to start in safe mode, also. All I get, is the above message...nothing else.

I'm not using that extension, so I do not know which files are used in addition to sessionstore.js and you need to check the profile folder yourself for suspect files.
This can be a problem with the file [http://kb.mozillazine.org/sessionstore.js sessionstore.js] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]<br />
Delete the files sessionstore.js and sessionstore.bak and any existing files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js .
See http://kb.mozillazine.org/Session_Restore
