    Yeah,
    I know, I should read all the other posts first - tried but didn't really know exactly where to start. Here is the story:

    I just bought a new motherboard for my pc (M3A78-EM) and successfully installed it. Yet, surely, a plain motherboard does not have any SLICs.

    I would like to add W7 SLIC 2.1 (Asus) to my BIOS (AMI) and I would like to do it myself. I never did anything like this before, so, anybody who is willing to give me some guidens is more than welcome!

    In addition: is there an easy way of changing the BOOT screen in an AMI BIOS?

    My motherboard's product page can be found here:
    http://www.asus.com/Product.aspx?P_ID=KjpYqzmAd9vsTM2D

    Thanks in advance!

    I have not done this, but from what i have read, ami and award are the two simplest to mod your bios for.

    Have you checked to see if there already is a bios modded on this site?

    1.You would want to start by downloading the latest "untouched" bios rom file from Asus for your motherboard, which I think is currently version 2003 ... and I think that bios rom will have slic 2.0

    2.You then want Asus slic 2.1 and Asus 2.1 Certificate, which you can get from here http://forums.mydigitallife.net/threads/5952-Win-7-Server-08-R2-SLIC-2-1-Bin-Collection

    3.Then you need tool for the job (amitool v143) from here http://forums.mydigitallife.net/threads/4071-New-AMI-BIOS-tool-for-performing-SSV2-3-and-Dynamic-SLIC-Modification ... there will be a folder with the tool called SLP ... that will have Asus txt file in it, that is used to add slp 1 string.

    4.Run the tool, browse it to your downloaded Asus bios, make sure it says Asus as manufacturer, add your slic 2.1 and 2.1 certificate to it and the Asus slp1 txt .... and if it says it sees slic 2.0 already present, is it ok to modify ... click yes.... it will auto run filling in menus by itself ... and after about 15 seconds will be done ... and produce new modded bios file.

    Last thing, very important, ... download all of the above stuff, and make a modded bios, and experiment with the tool .... but do not install the bios you make, ask on Bios Mod thread for an experienced bios modder to make you a modded bios for your PC ... you have a brand new motherboard there, and like you said, you havn't done this before ... all bios modding/flashing is risky, so reduce the risk.

    Good luck :)

    The above instructions by searchengine are pretty good but,
    NEVER add the Certificate into the SLIC Tool while doing a MOD (It can cause problems with the mod).
    Only enter it in after you reload the modded BIOS file into the SLIC Tool and if you are NOT Sure it matches your SLIC.BIN that you added to the BIOS.
    All of the SLIC.BIN and Certs provided by MDL come in matching sets so it really is NOT necessary to check the validity of the SLIC / Cert Match.

    Also,
    If the window that says SLIC 2.0 already present pops up click on CANCEL NOT OK.
    Then try the SSV3 Method with the MMTool button ticked (Usually the Best method for this type of ASUS Board).

    Only use the Dynamic Method (Which is much less safe than the SSV3 Method) if the SSV3 method fails to add SLIC 2.1 properly on this particular BIOS.

    Yeah,
    Those are pretty cool and easy-of-use instructions / tools, yet, as mentioned in my initial post: I would like to do it myself, meaning, I would like to learn how to edit an AMI BIOS, change things, add things and so on. The tools are doing all the fun work for me, so, there is no excitement.

    One of the reasons why I would like to learn it myself: There are a couple of BIOS settings which are enabled on default and I would like to change that. For example, a Floppy drive is always 'enabled' when I restore factory defaults even though there is no Floppy installed on my computer.
    Adding the SLIC Tables to my BIOS is only a bonus for me, yet, getting the BIOS really 'customized' is my main goal, if you understand what I am talking about? :)

    Also, does anybody know how to extract / change the BOOT SCREEN on AMI BIOSes? As far as I know, this should be a stright forward DCX format, isn't it?

    @NoJuan999 ...

    cheers, I hadn't realized should not add Cert at same time as Slic ... I'll remember that, next time I mod my bios :cool:

    @Junner2003 ...

    ASUS Update v7.17.02 will have a MyLogo.exe in it, that can be used to change bmp image of Bios Boot Logo ... support 640x480 256 colour images ... incorrect image sizes and colour depths can result in bad bios.

    Extra noob here and i'm messing around without flashing my bios yet *In learning phase* :p

    With MMTools i extracted "OEM logo" module from my maximus formula bios to my desktop and opened it with IrfanView , it said its a GIF image have a look here

    Looks horrible and i want to change it . Just like searchengine said , i have read it must be under 150 kb, 256 colors and exactly 640x480 size. MyLogo seems to adjust the image to these values (not file size) but i don't trust it, so better make sure your image is corret with another tool before using it.

    According to MMTools , MyLogo changes "OEM logo" module to the new image then throws it at another ram location , not sure why :confused:.
