  • Satellite L300-01:00 - DVD in PIO mode, cannot activate DMA mode

    Hello everyone,

    Recently, I have a laptop Toshiba L300-01:00 and I have a little problem with the DVD-ROM drive. Maybe some of you can help me with their knowledge. So here's the problem:
    The DVD runs very slow, I guess in the PIO mode. I can't switch to DMA mode because there is no options.

    On ' Device Manager / IDE ATA/ATAPI controllers ' options are a single - 'Intel(r) ICH9M-E/M SATA AHCI Controller' where you cannot activate DMA mode.

    I have WinXP SP2, SATA and all the other drivers installed.

    So my question is, how can I enable the DMA mode for the DVD player?

    Thank you very much.

    Hello

    I have a laptop with installed U400 XP OS and I the primary IDE channel entry into the IDE ATA/ATAPI controllers.

    Main channel that you can switch to the PIO or DMA is available in IE.

    Now the question is; How do you install XP on your laptop?
    Usually, the SATA mode must be set to AHCI in the BIOS, and you must include the SATA drivers to install Win XP on this laptop.

    Then a primary IDE channel should if poster in devices and the PIO or DMA settings manager should be there.

  • Support for devices on network HP service does not start

    The problem might actually be an add-on or another program to the origin of the problem and you should check that
    1st.

    What antivirus/antispyware/security products do you have on the machine? Be one you have NEVER on it
    machines, including those that you have uninstalled (they leave leftovers behind which can cause strange problems).

    Start - all programs - Accessores - system tools - IE with no Addons - does this work better?

    IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

    IE - Tools - Internet Options - Security - reset all Zones by default level - apply / OK

    not better?

    Close IE and try again IE or IE with no Addons

    IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
    "(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.

    Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
    are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.

    Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
    are bad, but some can cause your question. (Toolbars are BHO)

    Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that would be unusual with
    Prevx running except a low occasional (not much), updated cookie, and then run it as a scanner.

    I would add prevx so.

    Prevx - Home - small, fast, exceptional CLOUD free protection, working with other security programs. It comes
    a scan only, VERY EFFICIENT, if it finds something to come back here or use Google to see how to remove.

    will not uninstall and I get an error message, which has in its title "Microsoft SQL Server Compact 3.5 for Devices", (which seems to me indicate that he might be from the application itself?)

    Is there a valid way to uninstall this, given the problem - or an another workaround?

I have selected SQL Server Compact 3.5 for Devices in the list. They asked me if I want to uninstall it (I think that - already done and I do not remember)-anyway, I welcomed the utility for uninstall and there was no problem. It is very useful.

  • Turn on DEP for all programs or Just essiential

    OK, I have windows 8 and my processor supports hardware (Data Execution Prevention) adj. I sorta understand the concept of DEP however not enough to know whether it should be enabled for all programs or all necessary programs or since my processor hardware DEP can I disable DEP Windows?
    All the information to help me understand better and an answer would be thank you much.

    Hi Peter,.

    Data Execution Prevention (DEP) is a security feature that can help prevent damage to your computer from viruses and other security threats. Harmful programs can try to attack Windows by attempting to run (also known as execute) authorized the code from the locations of memory system reserved for Windows and other programs. These types of attacks can affect your programs and files.

    DEP can help protect your computer by analyzing your programs to make sure that they use the system safely memory. If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you.

    It is not recommended to disable the DEP. DEP automatically monitors essential services and Windows programs. You can increase your protection by having DEP monitor all programs.

    First, see if a version compatible DEP for the program is available by visiting the website of the software publisher. If the Publisher has not released an updated, compatible version DEP for the program, you can turn off DEP for the program that was closed. You will be able to use the program, but it might be vulnerable to an attack that could spread to your other programs and files.

    If you choose to turn off DEP for a program, it's a good idea to check frequently for an updated version of the program and, after you update, to turn on DEP again.

    Let us know the status of the issue. If you need help, please after return. We will be happy to help you.

    I am one of my apps Android AIR of CS5.5 to animate the portage.

    I can't download it to devices that run Android 2.3.x versions. The problem seems to be that by default what android SDK of AIR conditioning with Animate is version 20, but the devices running Android 2.3.x seem to be stuck on the AIR 19 runtime. I downloaded Android SDK of AIR 19, but when I tried to switch to it using 'manage AIR SDK... "I get an error message saying that I can't upgrade to a version of AIR lower than the preinstalled version. Still, I have many users using devices that run Android < 4 versions and won't leave stranded. What can I do to fix this?

    Yet can the old way to overlay a term I used in CS5.5, be used? I never tried to superimpose an OLDER version of the SDK on CS5.5, then perhaps it would not have worked either.

    In the part of the descriptor XML app Android, you can set the minimum level of SDK, like this:

    This has been very convenient for the times where I wanted to make sure someone is on Android 4.0 or later. But it may be worth trying as a way to override the default used by AIR. You can try to use the 9 or 10, depending on whether you think that your users would have at least to 2.3.4.

    Or, do not worry them, they always take advantage of your old version.

Maybe you are looking for
