    (I have aspire v5 122p, bios v2.06 - see my previous post)
    In Ubuntu, I opened Ubuntu Software Center and searched for/downloaded Ghex.
    Then from terminal-> sudo apt-get install ghex
    then-> ghex filename

    I may have to downgrade the BIOS back to 2.06.

    2.09 won't load any GUI on any distro I've tried thus far (Ubuntu, ArchLinux, Mint). So no software centre for me...

    I updated to 2.09 the week it came out. I haven't seen any issue with it. (In fact, suspend now works with Linux as well, which is nice since after suspend the cpu is "sort-of-unlocked" at can run 1.4 GHz on all 4 cores at the same time).

    If you are at the stage with access and you could copy the file to the windows partition (ntfs-3g can do that) and modify it with your favourit tool... and copy it back once you edited the bits. (That or get another usb stick)

    hi, first, i sorry because am mexican and i don´t know a lot of english.

    i bought a Aspire V5-122p-0680 and i did try to do this because i really needs VT.

    i try with diferents distros of linux. including many procedures to install it on a usb. i read before and i thought that this could be about bios but when i check this was 2.04 so it was not razonable...

    but i found a problem... it doesn´t about the distros... it is about the drivers...

    my video card is amd radeon hd 8250... i found this a help on google but you must install a linux and connect it to wifi, but i really dont want to install a linux on my pc :( and i cant connect by console to wifi... it told me the encryption error... so if you know how to create a live distro with drivers... or graphics safe mode... tell me =( i will research...

    well i research a little, i only found that we can use a distro like ubuntu or kubuntu ("because wifi drivers") and use persistence... with a little program called unetbootin... its night but i will try tomorrow.

    persistence leave you to download the drivers, and reestart with that you do before reestart... sorry for my english again. i will try tomorrow. luck to me :)

    Hi mackiur,

    You know what? I think you're correct. I have a European, non-backlit (model: MS2377) version.

    Tried all the instructions in this thread, correct Ubuntu distro, correct image writer, multiple memory sticks, both ports...

    Nightmare.

    I can't get past the "no screen found" issues either, so can't boot in to an distro because of errors with "plymouth".

    There are solutions as you have seen, but they require installing Linux, dropping to commandline, connecting to wifi and pulling down a fresh radeon driver...
    I see you've tried this and had an issues with the wifi, so did I, it looks to be a wifi card driver issue...

    I don't know what the solution is, but at least you're not alone!

    Acer Bios 2.24

    I am also trying to activate virtualization on an Acer V5 573P, I have bios version 2.24.
    Does anyone knows at which offset it is located?

    Regards

    erm? why you ask :animatedwink:?

    You can look for it too. No special "skillz" or "toolz" required. Just start a new thread and pool the resources there :zwinker:.

    BTW: I hope the sutile "suggestions" aren't too obvious. :yeah:

    Oh one more thing (tm): The linux uefi access method needs an extra +4 for every offset which is taken out of the uefi dumper tools.
    This is due to the implementation of the access (the first 4 bytes are in fact part of a meta-data bitmap).

    Thank you

    I was able to do this with Fedora 20. Note: vim / xxd did not work for me. What I did was to copy the original file ( as root) cp /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-395113002113d /root Edited with hexedit (xxd did not work) and then copied the file back

    Hi there,

    I tried this and got to editing the efivars/Setup-.... file, however vim wouldn't let me save my changes, saying fsync failed.

    So I then installed ghex and tried to use that, but it just came up with a blank window when I tried to open the file.

    I then went back to trying in vim, but noticed about half of the file had disappeared :/

    I then gave up and decided to restart my laptop. Now the screen doesn't turn on at all. The lights turn on and the computer makes noise, but the screen remains completely black.

    Do you know if there is anything I can do to rescue it? Any help would be much appreciated.

    I'm new to this forum, so Hi everybody.

    I suceeded in activating SVM on my new laptop aspire-v5-123,
    It is a cheap laptop with amd E1-2100 and radeon HD 8210, I bought it mainly for its price,
    and because AMD E1-2100 has hardware AES crypto, and VIRTUALIZATION also...two things I need....

    I first turn it to legacy mode, wipe out windows 8 , and install xubuntu 14.04 instead in legacy mode..

    than I boot with uefi, with a usb stick with live version of xubuntu 14.04 on it,
    the /sys/firmware/efi/efivars was automatically mounted for me..

    I edited the file /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39411302113d
    with ghex (wich I have previously install with: sudo apt-get install ghex)

    the offset was a bit bifferent on the aspire-v5-123 , it is 0x72
    so I just write 0x01 at the offset 0x72, write the change..
    turn the computer off.
    turn it back to legacy mode, and start xubuntu...

    and svm was activated, cool !!!
    I try virtualbox , wich runs perfectly in 64bit mode and enough fast to be usable...

    the bios version is 2.05 (the last one at the time I write)
    I hope it will help someone...

    PS: I tried to activate the hidden features of the bios, but I didn't fund the right offsets for the aspire-v5-123
    I will try again later... I inform you if I found the good offsets

    Just want to add 0xf4 is the location (same) on new Acer AMD E5-421G to enable SVM virtualization. Acer really do suck by disabling this. Virtualbox running at much faster speed now (and with option of 64bit guests)

    Hi
    I also like to activate the hidden pages in my efi. I have the Acer V5 573g intel i5, nVdiagtx850m. If I remember correctly, the BIOS version is 2.24

    How do I find the correct positions? I have no clue.

    My hexdump
    Code:
    hexdump -C /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    Hi Interzone,

    I've recently bought the same aspire v5-123 computer as you and I've trying for the past day to activate the virtualization with the indications I've read on this thread. And I was so happy to read that you had the exact same configuration as mine (BIOS v2.05, AMD E1-2100) - but when I looked at editing the file /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39411302113d, the offset 0x72 was already configured on 01.

    I'm a novice and I do not want to tinker too much with what I do not know. Could you help me out?

    Many thanks in advance!
