  • What does an ACPI BIOS configure during boot?

    - by RJSmith92
    When a PC boots with an ACPI BIOS, what does it exactly do? I understand that the point of ACPI is to allow the OS to control hardware resources and power management but before the OS is loaded does ACPI configure just the devices needed to boot and then let the OS configure the rest? If the OS wants to re-asign hardware resources does it store this information in the ACPI tables so that the next time the system is booted it assigns them how the OS wants? The ACPI driver asks the PCI bus driver (Pci.sys) to enumerate devices on it's bus once the OS is loaded, how are these devices configured whilst the PC is booting when it doesn't have other bus drivers? Any help with any of the above questions would be greatly appreciated. Thanks.

  • Updating windows xp hard drive controller from ubuntu live disk

    - by Joel
    The problem: When booting, I get a blue screen shortly after the Windows XP logo splash screen. The error code is 7b, and the second hex number is 0xC0000034. Based on this link (item 7) it appears the driver should be updated. Oddly, I made no changes to the drivers recently. I suspect it was something in a windows update or the newest upgrade of my antivirus (eset). But I digress. The BSOD makes me unable to boot into Windows at all, so I can't update the driver from there. I've run various bios-level diagnostics (including full surface scan) and the hd looks good. I'm also able to boot to an old ubuntu disk and read files from the hd. The question: Based on the above, it appears that I need to update the Windows hard drive controller from the ubuntu live disk. How do I do that?

  • Dell V105 printer and OS X 10.6

    - by James
    I am trying to get a Dell V105 printer to work with my iMac. It is running 10.6 and I have installed all the drivers on the Snow Leopard disk. I believe there is no official Dell driver but I have also heard the Dell printers are made by third parties that may sell the same printer under different names. There a quite a few Lexmark models that seem to look very similar and I have tried setting the driver to the 2600 series that looks very similar but that has not enabled me to print. Although it claims to give me the supply levels correctly. Can anyone help? Thanks for your time

  • Connecting slots and events in PyQt4 in a loop

    - by LukaD
    Im trying to build a calculator with PyQt4 and connecting the 'clicked()' signals from the buttons doesn't as expected. Im creating my buttons for the numbers inside a for loop where i try to connect them afterwards. def __init__(self): for i in range(0,10): self._numberButtons += [QPushButton(str(i), self)] self.connect(self._numberButtons[i], SIGNAL('clicked()'), lambda : self._number(i)) def _number(self, x): print(x) When I click on the buttons all of them print out '9'. Why is that so and how can i fix this?

  • Can I avoid a threaded UDP socket in Python dropping data?

    - by 666craig
    First off, I'm new to Python and learning on the job, so be gentle! I'm trying to write a threaded Python app for Windows that reads data from a UDP socket (thread-1), writes it to file (thread-2), and displays the live data (thread-3) to a widget (gtk.Image using a gtk.gdk.pixbuf). I'm using queues for communicating data between threads. My problem is that if I start only threads 1 and 3 (so skip the file writing for now), it seems that I lose some data after the first few samples. After this drop it looks fine. Even by letting thread 1 complete before running thread 3, this apparent drop is still there. Apologies for the length of code snippet (I've removed the thread that writes to file), but I felt removing code would just prompt questions. Hope someone can shed some light :-) import socket import threading import Queue import numpy import gtk gtk.gdk.threads_init() import gtk.glade import pygtk class readFromUDPSocket(threading.Thread): def __init__(self, socketUDP, readDataQueue, packetSize, numScans): threading.Thread.__init__(self) self.socketUDP = socketUDP self.readDataQueue = readDataQueue self.packetSize = packetSize self.numScans = numScans def run(self): for scan in range(1, self.numScans + 1): buffer = self.socketUDP.recv(self.packetSize) self.readDataQueue.put(buffer) self.socketUDP.close() print 'myServer finished!' class displayWithGTK(threading.Thread): def __init__(self, displayDataQueue, image, viewArea): threading.Thread.__init__(self) self.displayDataQueue = displayDataQueue self.image = image self.viewWidth = viewArea[0] self.viewHeight = viewArea[1] self.displayData = numpy.zeros((self.viewHeight, self.viewWidth, 3), dtype=numpy.uint16) def run(self): scan = 0 try: while True: if not scan % self.viewWidth: scan = 0 buffer = self.displayDataQueue.get(timeout=0.1) self.displayData[:, scan, 0] = numpy.fromstring(buffer, dtype=numpy.uint16) self.displayData[:, scan, 1] = numpy.fromstring(buffer, dtype=numpy.uint16) self.displayData[:, scan, 2] = numpy.fromstring(buffer, dtype=numpy.uint16) gtk.gdk.threads_enter() self.myPixbuf = gtk.gdk.pixbuf_new_from_data(self.displayData.tostring(), gtk.gdk.COLORSPACE_RGB, False, 8, self.viewWidth, self.viewHeight, self.viewWidth * 3) self.image.set_from_pixbuf(self.myPixbuf) self.image.show() gtk.gdk.threads_leave() scan += 1 except Queue.Empty: print 'myDisplay finished!' pass def quitGUI(obj): print 'Currently active threads: %s' % threading.enumerate() gtk.main_quit() if __name__ == '__main__': # Create socket (IPv4 protocol, datagram (UDP)) and bind to address socketUDP = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) host = '192.168.1.5' port = 1024 socketUDP.bind((host, port)) # Data parameters samplesPerScan = 256 packetsPerSecond = 1200 packetSize = 512 duration = 1 # For now, set a fixed duration to log data numScans = int(packetsPerSecond * duration) # Create array to store data data = numpy.zeros((samplesPerScan, numScans), dtype=numpy.uint16) # Create queue for displaying from readDataQueue = Queue.Queue(numScans) # Build GUI from Glade XML file builder = gtk.Builder() builder.add_from_file('GroundVue.glade') window = builder.get_object('mainwindow') window.connect('destroy', quitGUI) view = builder.get_object('viewport') image = gtk.Image() view.add(image) viewArea = (1200, samplesPerScan) # Instantiate & start threads myServer = readFromUDPSocket(socketUDP, readDataQueue, packetSize, numScans) myDisplay = displayWithGTK(readDataQueue, image, viewArea) myServer.start() myDisplay.start() gtk.gdk.threads_enter() gtk.main() gtk.gdk.threads_leave() print 'gtk.main finished!'

  • Sound card doesn't work and yet does.

    - by Xeoncross
    I have a really weird one tonight. Today we had a LAN party and all of a sudden the sound on a couple PC's stopped working for programs like the games, windows media player, etc. However, when errors would popup (like trying to change the volume settings) you would here the default error chime. Restarting the computers you would here the logoff-login sounds and after a restart the sound would work for a bit in both games and apps and then suddenly stop. Restarting also didn't always fix the problem. I can't figure this out. If the sound card/driver didn't work then how could we hear sounds from the windows sound scheme? No sound with VLC, windows media player, youtube, games, nothing. The only thing I can figure out is that this is a bad game crashing the primary driver or some kind of weird virus these PC's might have picked up.

  • Counting amount of items in Pythons 'for'

    Kind of hard to explain, but when I run something like this: fruits = ['apple', 'orange', 'banana', 'strawberry', 'kiwi'] for fruit in fruits: print fruit.capitalize() It gives me this, as expected: Apple Orange Banana Strawberry Kiwi How would I edit that code so that it would "count" the amount of times it's performing the for, and print this? 1 Apple 2 Orange 3 Banana 4 Strawberry 5 Kiwi

  • What's the logical value of "string" in python?

    - by Kamran
    I erroneously wrote this code in python: name = input("what is your name?") if name == "Kamran" or "Samaneh": print("That is a nice name") else: print("You have a boring name ;)") It always prints out "That is a nice name" even when the input is neither "Kamran" nor "Samaneh". Am I correct in saying that it considers "Samaneh" as a true? why? By the way, I already noticed my mistake. The correct form is: if name == "Kamran" or name == "Samaneh":

  • HDMI and DVI connected monitors not in dual view on Windows 7 (Intel onboard Gigabyte)

    - by Nux
    I have a HDMI to DVI cable which is connected to one monitor (HDMI is on PC side) and DVI-DVI connected to other monitor. This seems to work up until the system is fully loaded (the startup logo animation is shown on two screens). When and after I log in only one monitor is active (HDMI-DVI). I'm also unable to detect the other monitor (DVI-DVI). Any ideas what might be wrong with the setup? Also when I uninstall the Intel Graphics driver both screens are on, but only duplication works. GA-Z68A-D3H-B3, Intel Z68 Chipset, with fresh VGA driver (15.26.1.64.2618).

  • Dark Windows 7 Screen

    - by user147521
    My Gateway laptop -Windows 7- screen became too dark a few days ago after I finished installing Windows automatic update. I can see nothing unless I use a flashlight. Windows login screen is the only bright screen for few seconds. What should I do to resolve this issue? I checked power-saving/ Power Options settings and rebooting in Safe Mode. I tried to lower the refresh rate but it did not allow me. The laptop adapter type is ATI Radeon Xpress series. I uninstalled and reinstalled the driver. And the driver is up to-date. Any help would be appreciated.

  • iPad USB Charging Utility for Dell Optiplex

    - by BreakPhreak
    As you probably know already, an iPad requires a certain power on USB port to be charged from. Thus, some motherboard manufacturers (such as ASUS, Gigabyte etc) had released a special driver that recognizes that an iPad is connected to the port and adjust the USB power accordingly. On one of my computers (Gigabyte motherboard) it works fine. But other one is Dell Optiplex 780 and the regular googling by "<motherboard type> + iPad charging" doesn't seem to bring encouraging results. Just for completeness: no, the iPad is not being charged without any special driver installed (out of the box) either. Any suggestions will be welcomed.

  • SQL Server - Test the result of a stored procedure

    - by Melursus
    In SQL Server, it is possible to test the result of a stored procedure to know if the result return rows or nothing ? Example : EXEC _sp_MySp 1, 2, 3 IF @@ROWCOUNT = 0 BEGIN PRINT('Empty') END ELSE BEGIN PRINT(@@ROWCOUNT) END But @@ROWCOUNT always return 0 so maybe is there another way of doing this ?

  • How to flip video feed that's presented upside down?

    - by Zuul
    Skype an other applications running under windows 7 Ultimate are presenting the video captured from the laptop built-in webcam upside down. I've tried many solution that I was able to find regarding issues like this, but to no avail. Some of the most relevant are discussed here: From Skype Support Network, the thread why is my video image of myself upside-down??? From ASUSTek Forums, the thread Built-in camera upside down Both present several potential solutions to this issue, but I've been unable to fix it for the laptop ASUS U6S. What I've already tried: Changing Drivers The driver that works must be the one from Windows, all others available from ASUS drivers either don't install or install but the webcam doesn't provide any video feed. This disallows all options that concern using an older driver or editing the .inf file as to manually adjust the settings. ASUS does not provide drivers for Windows 7, so I've used drivers from Windows Vista 32 Bit. Using the application manycam This application actually solves the issue (temporarily), but creates new ones: If I use the application to flip the video feed, Skype video call cease to work. This application doesn't save the settings, at least I wasn't able to find any way to save the settings I've used to flip the video feed. A computer restart brings all back to how it was, video feed upside down and if the application is still installed, Skype continues to fail on video calls. Regedit I've searched thru Windows Registry Editor as to find any reference to the webcam settings, hopping to find a key with the Flip parameter, since it's up to the driver to flip the image (by what I could ascertain from this problem). Couldn't find any reference to such settings, either they actually don't exist within the Windows Registry or they use some weird name that I could think off. System Configuration I was able to access the webcam system settings from the Windows Device Manager, but the tab that actually has the Image Rotation setting is always disabled. The same goes for the settings available from the Skype webcam options (that essentially is presenting the same settings as Windows Device Manager, just within a custom Skype pop-up). Question: How can I flip the video feed from the laptop's built-in webcam, as to properly see and broadcast the video?
