    Sucess!!!
    Ive modded the Bios of the Acer 5750G(INSYDE)
    I used the Acer Aspire 5742G Guide to do so.
    forums.mydigitallife.net/threads/23762-ACER-5742G-BIOS-modding-(unhidden-pages-enabled-UEFI-BOOT)

    The Procedure is quite the same,the Offsets for the 1.1 Bios from 5750 are:
    Code:
    STRING_TABLE = 0x262d0
    
    storage_map = {}
    
    FORMS = [
    ('Main',0x20a70),
    ('Exit',0x20b00),
    ('Boot',0x20cd0),
    ('Power',0x20ee0),
    ('Security',0x211e0),
    ('Advanced',0x21ac0),
    ('Information',0xa46f0),]
    The Offset for the UEFI Switch is: 20DC7

    Code:
    +Suppress If
        EQ [0x1fc<1>] == 0x0
        One Of [0x1fd<1>] 'AES'
        \Help text: 'AES(Advanced Encryption Standards).'
         Option 'Enable' = 0x1 Flags 0x11 Key 0x0
         Option 'Disable' = 0x0 Flags 0x10 Key 0x0
        End One Of
       End If 

    Then i opened the Acer 5742G SetupPE in IDA and looked for the Offsets of the modded "Power and Advanced" checks.
    So i have got a plan how to mod the 5750G Bios:
    Found out that
    .text:00000001800013C2 cmp ecx, eax (3BC8)
    .text:00000001800013C4 jz loc_180001487 (0F84BD000000)
    and
    .text:00000001800013E1 cmp ecx, eax(3BC8)
    .text:00000001800013E3 jz loc_180001487 (0F84BD000000)
    are responsible for the missing "Advanced" and "Power" Tabs
    So i "NOP"┬┤ped the Areas(13C4 and 13E3 with 6x Nop(0x90)) and tada! All the Tabs are there.
    Heres the Bios(V1.1) for the 5750G with the Modifications:
    mediafire.com/download.php?mc6il2pi96b1j87

    Ive also made a sheme for modding similar BIOSes for Acer Notebooks:
    biossheme.jpg
    It isnt difficult,you should simply make the Procedure with the 5742G Bios,and then youll be able to do it,with probably any Acer Bios which is similar.If you have Questions,ask me anytime.

    so what are the advantages of having this BIOS? what do you think was the largest advantage having this modded one over having the official one?

    I have a 5750G notebook and I would like to have SLIC 2.1 in it but now wonder if I should use this BIOS as a base? or should I stick with the original?

    It has all the options unlocked in the BIOS. I dont have a Clue if SLIC 2.1 is present in the BIOS,cause my Acer 5750G has the Slic Table already. You should give it a try,if you want to have alle the options unlocked. If not,ask for a SLIC solution in the "INSYDE BIOS Mod request" thread.

    Modded it with the method from forums.mydigitallife.net/threads/23762-ACER-5742G-BIOS-modding-(unhidden-pages-enabled-UEFI-BOOT)
    hotfile.com/dl/124567391/8c59429/XEWxx213_SLIC.rar.html
    No Warranty. But it should do the trick. If not,i could try to enable all the Options using another trick described in another Thread. Use it on your own Risk.

    @ilia1990: How did you follow the tutorial from the Acer 5742G topic ? I couldn't find "lzmadec.dll" anywhere, and the python command doesn't seem to work :punch: thus I couldn't continue with the modding. Can you provide more in-depth instructions or may you help me with this one ?

    The Dll is found here: //rajko.info/acer/tools/ in the "python-scripts" file.

    I have another method to unlock all options:
    1 Open Bios file (*.fd) with Phoenix Tool Bios Slic Mod-Utility.
    2 Get the SetupUtility PE from the Dump Directory(simply search for the Biggest File there. It should be the PE)
    3 Open File with the IDA 64Bit.
    4 Follow the Guide on my Picture(added as Attachment)
    5 Reassemble the Bios file.To do so,you need to do following:
    -> open Bios File with the Phoenix Tool.
    -> click on Options
    -> Check "Allow user to modify other modules" and "No SLIC"
    -> Click ok,let the Phoenix Tool work. It will ask you to make your modifications
    -> Replace the SetupUtility PE-File in the DUMP Directory with your modded one
    -> Click ok at the Phoenix tool. It will give you a valid Bios File.

    Ilia, can you mod the newest official bios for 5750 ver. 1.12.

    It's very important - cause in this bios acer trully enables AES,also video bios for both intel and nvidia is updated,cpu microcode is updated too.

    From now on AES works just fine in everything like Aida 64 extreme,wi-fi etc....and also it is correctly detected like progs cpu-z......

    Done,
    mediafire.com/?ul8c7gc0mey7bi1
    Use at you own Risk!
    PS: Good Bios,like the new AES-Intructions. But the unlocked Options arent necessary,cause Acer set all options to the best values.
