    Is there anyway an ASUS board with a UEFI BIOS can be modded to activate Windows 7 or must I use an activator?

    I have the Asus Sabertooth Z77, it's about one yer old now. As soon as I bought it I modded the BIOS myself.

    With the files slightly modded on my Windows 7 USB3 install disc UEFI runs sweet.


    Dont really know what the drifferance is but it does run smooth.

    Hope this bit of info helps

    I read through your options. I do not know which would be the best to do. What are the dangers of each way? If I do a clean install of W7 without modding can I use Microsoft Toolkit or DAZ Loader to activate? I read somewhere that the Enterprise edition can be activated.

    There is always a certain degree of risk with flashing a BIOS but the newer boards makes the risks a whole lot less.

    What I did was to save the BIOS which was pre-installed, I modded that then re-flashed the modded one back using the Asus Ezay Flash Tool from within the BIOS tools. This worked a treat and it would not flash if it knew the BIOS file was corrupt in anyway. Less risk of bricking the board.

    What Asus board do you have. My Sabertooth is not the only Asus UEFI board I have done, no problem with any.

    Just to add, I have not added Windows XP SLP info just SLIC 2.1 for Windows 7.


    P,S I used the DYNAMIC method, did not want to add SLIC perminatly.

    The board is on a friends computer. I will find out what board it is and get back to you. He is not interested in XP just W7 Pro or higher. I think that it should also be a permanent mod. Why would I want it to be dynamic?

    ahhhh, so your gunna be doing a mates PC...

    My take on this is, I have seen no benefits on running UEFI with HDD setup on GPT. Only thing I know of is MBR does not recognise drives over 2TB.

    So unless your mate is planning on slinging in a 3TB HDD or infact wanting full benefit from using a SSD I would simply install Windows 7 Ultimate and use Daz's loader. No risk of a bad flash what so ever and the loader works perfectly.

    Format the drive to MBR, this is the normal way let's say and your good to go.

    Having said that,find out what board it is and you never know it may have already been modded,

    bet this has made it even more unclear...;)

    I know all he wants is Windows 7 Pro. He does not have a SSD or a drive larger than 1TB. It currently has W7 pro but will not activate with Microsoft toolkit. What he did was take the drives from his HP PC that died and put them in a new case with the UEFI board and it booted right to windows. Could it be because it is the HP activated windows? I know with a regular BIOS you can check the SLIC with RW-Everything, does it work with a UEFI BIOS?

    I just found out the board is an ASUS Gryphon Z87

    Only Pro & Enterprise can be activated by Microsoft Toolkit.

    RW-Everything can be used on UEFI systems as well.

    As I said before, a permanent bios mod is perfect solution for him.

    That looks a nice board,

    If you fancy, later I will download the latest BIOS file for that board and run it through the mod tool adding Asus SLIC 2.1 info.
    I will see if the process goes well and tell you the result.

    What I would if it were mine is once the BIOS hods SLIC 2.1 I would do a whole fresh install of the choice of W7. Format the drive into GPT, make a UEFI usb install stick with the corresponding OEM info,or using DISM integrate the CERT and key directly.

    Going down the mod route will help for future hard drive upgrades.

    Have you flashed many boards ? The Z87 should be nice and easy.

    You can't flash back the modded bios if you use default Dynamic method. You have to mod it using New Module method or using MMTool.

    Nice bit of info there. Thanks very much.

    Can I ask why this would be. The last Asus board I did was my Z77, I am pretty sure I used the Dynamic method. I know I saved the pre-installed BIOS and modded that, is this why.

    Used the Asus Ezay Flash Tool within the BIOS tools.

    To add. Seeing it has been a little while modding my last BIOS I will make sure I read through the guides and download the latest versions.

    Even just for my own benefit.

    Asus has implemented secure bios flashing feature in latest Haswell mobos & some older Ivy Bridge mobos. Thats why you can only flash modded bios through EZ-Flash or Asus's flasher only if it contains valid signature.

    Hello,

    if I use NewModule method or using MMTool to mod my bios ezflash or bupdater will pass and can be flashed
    but if I patch other module it can't flash "security verification error"

    How phoenixtool and mmtool can handle secure flash signature
    can be used to patch other modules

    New Module method is basically same as modding using MMTool. The interesting part is the signing key which is present in KEY\OA.TXT of Phoenix Tool folder. It is derived from a leaked package of MMTool. I'm not sure how it can be useful for inserting other patched modules.

    :g:

    I have just been messing about using the latest BIOS file for my Asus Z77 board, using the Phoenix Tool v2.19.
    It asked for a "key File", now I can not remember inputting this before.

    Can I ask, what KEY is it, by looking, it's not the KEY I first imagined it to be, i.e Windows 7 key. ( Don't know whay I thought that )

    On the BIOS file I tested the process worked fine using "New Module"

    Did NOT use a RW Everthing file... Just downloaded that now.

    -------------------------------------------------------------------------------------------------------------------------------

    Just tested once again, New Module and added my saved RW Everything file.....Worked a treat.

    I may well have to test this out and flash my mobo with the very latest Asus BIOS, adding SLIC 2.1. I know my BIOS is old but I went by "If it aint broke,don't mend it"

    RW report is completely optional for UEFI modding. You can safely ignore it.

    For answers about the 'key', read the post just above yours.

    ahhhhhhhhhhhhhhhhhh... I read that, reading it again it makes sense, this is what's going to sign the modded BIOS and fool the board into thinking this is a genuine BIOS file.

    Or, does it actually mean by adding this leaked KEY the modded BIOS file is actually a proper genuine file but with extra info, the SLIC 2.1 info.....


    Tito...Thanks for this info and help.....:)
