BIOS problem, how downgrade

I'm updating the bios to 2.14 to 2.21 on my aspire E1 - 571. MY video ram on version 2.14 was 128 MB and is now on 2.21 64 MB. How downgrade bios 2.14 because 64 MB is bad for the game, when I go to install 2.14 has error message "Comparison of bios problem" Please help, help, help

Erkedo,

Avoid any problems flashing the BIOS to an older version. Did you do that there is no way to manually change the video memory setting in the BIOS?

  • How to report the BIOS problem?

    Hello

    is it possible to report the BIOS problem so that a person of HP it will read and the problem will be solved if all goes well?

    To be concrete, there seems to be problem in BIOS F.02 installed on HP Mini 5103 causes of freeze if it has plugged the USB key with 'recursive partitioning' at startup. As a result, it is not possible to boot from live USB which was created from some ISO hybrids (e.g. direct ISOs of OpenSUSE recent). Since there are not many options to install the system on netbook, I think it is serious problem. My previous netbook Lenovo Ideapad S10 - 3 and also my work laptop and desktop have no problem to start with the USB stick containing "recursive partitioning", so it's certainly a problem (hopefully not feature) this concrete machine/BIOS.

    Thank you

    That's ok on the Bravo, I did nothing to help you again.  This link is for questions of security, but it is also for the firmware, so you can get away with sending them a note here:

    Go to the BIOS.

    Save the changes and now you should be able to boot from the Windows 7 disc.

  • Satellite Pro A100 - BIOS problems: B-S-O-D & non-sync

    Hey all,.
    I recently updated my BIOS to 1.6
    After the update:
    -If I select "Shutdown" or "Restart", I get a 'blue screen of death' (a whole bunch of text too fast as I can't read), and restarted my laptop.
    -If I select "Logout" instead, followed by "Stop" or "Restart", while the laptop seems stopped, etc., correctly.
    However, even if it looks correctly stopped using the "Logout" approach, my laptop is now not sync'ing properly with my server.

    I am convinced that it is the update of the BIOS, as nothing has changed since the update (or even before the update).

    Is it possible, or rather, how downgrade / format / restore my previous BIOS?
    I would like to make an update of the previous BIOS (to Oct 2006), as well as the backup BIOS the BIOS before this 2006 update.

    Any help will be appreciated.

    Hello everyone,

    I made the mistake of updating my BB to Mac OS 10.2 to 10.3 Q5. The only problem I have is that the battery life is shorter with OS 10.3. With a Wi - fi connection, using whatsApp and browse the internet on Mac OS 10.2, the battery lasts 3 days, but on OS 10.3 lasts 2 days only... so please tell me how downgrade from 10.3 to 10.2. And another little detail: the wifi signal and stability is better on Mac OS 10.2 10.3

    How downgrade from Windows 7 Ultimate to Windows XP Home Edition?  I understand that what is happening back, but my printer & a lot of programs that I can not afford to replace now is not compatible with Win7.  I tried to insert the WinXP disc, but he says the facility is "blocked due to compatibility issues".

    Hello

    To install windows XP on windows 7, you need to start your computer while the cd is in the drive. This will allow the system prompts you to "Press any key to boot from the CD-ROM.." and then follow the instructions accordingly.

    I hope this helps.

  • Windows XP Bios problem

    When you install Microsoft XP, I seem to be a BIOS problem.  The error message loads up once the disc loaded files, but until you're able to partition the drive.  The error message indicates that the hardware and BIOS are not ACPI compatible.  After reading upward, I tried to correct the problem by what the error message says to do.  First of all, try to update the BIOS.  I called my computer supplier and received the last update for the BIOS of the computer.  I installed it and nothing happened.  I resorted to the second option listed that would press the F7 key. that was supposed to disable the ACPI and force the installation. It does not yet.  I then read a few forums and they said to update a file on the disk XP (TXTSetup.sif).  So I did but nothing seems to happen.  You have other options to get this facility by?

    First of all, check that you have not hit one of the components of the PC especially the memory sticks. If there is anything loose, see the article published below. It might be useful for you.

    Ok. You have not provided this information before. So my previous post was a waste of time. You will need to buy HP recovery media. If you are available and active recovery media recover image factory, it would be to delete and recreate the partitions on the boot only disc not the secondary hard drive.

    Looking for discs recovery or recovery usb media?

    2 what, reset or refresh the pc. This will help?

    N ° reset or update will only update to the current Windows 8.1 operating system

    3. is it going to be unilingual Windows 8 again.

    It will not work if there is no recovery partition, if you do not have to worry about that

    4. How can I stop the installation of windows 8.1 in the future.

    Change the settings for Windows Update. See the following image
