    Hi there
    I order a Samsung 900X3C-A04 ultrabook, and it should arrive tomorrow. It comes with Windows 8, and I want to format it and install Windows 7. I want to know if this kind of bios can be modded to add a slic 2.1 table, since I don't know anything about it (I can't download the bios file from the Samsung webpage, I can only download a program to update the bios which will only work on that specific model). I don't know if it's an Award bios, AMI, Insyde, etc, don't have a clue. Can anyone help me on this, or at least provide me with the last bios file for this model, to see if I can mod it myself? Please.

    Thanks

    You should run the updater on the laptop (when arrived) & it will tell you if any bios update is available or not.

    Thanks. That's what I was planning to do, but I wanted to know if somebody already succeded on that.
    My ultrabook arrived today, I managed to download the exe file of the newest bios. I used Universal extractor, 7-zip, winrar, etc., but I only could extract files that were not usable. One of them is 3.866 Kb (the other files are like 1 Kb), but couldn't open it with any of the modding tools posted here (for AMI, AWARD or INSYDE bios).
    Once I had a similar problem with a Vaio, and I could obtain the real bios file looking inside a carpet (don't remember which) after executing the exe file. Maybe that could be a solution. Can somebody help me? I want the real bios file to add a slic 2.1 table (I don't know if it's possible yet on this kind of bios), and I would appreciate it if someone could help me on that.
    Here is the link of the exe file I uploaded: sendspace.com/file/bchxli

    Thanks

    Upload the bios somewhere & give us the link.

    Most probably you need find_gz.exe to decompress it.

    RWE Report? So this is some kind of Phoenix/Insyde bios? I'll upload it as soon as the laptop arrives (it should be today).
    Tito: I uploaded the exe file to sendspace. The link is on my last post.

    Thanks

    The laptop arrived. I'm running RWE and trying to access the ACPI tables, but it's gives an error message: "ACPI RSD PTR not found". And I did run the program as an administrator. Is this some kind of new or different bios? As I said, I couldn't extract a bios file from the exe file I posted on this thread (just a 3.866 Kb file that couldn't be opened by any bios mod tool), and can't generate a RWE report. Any ideas? A couples of posts above I posted the link to the exe file, if someone wants to help me :).

    Thanks

    I already did that. It gives the same error (Dump error, RSD PTR not found).

    Well, I used the Universal bios backup toolkit by DavidXXW and it says it cannot identify the bios. It works well on my desktop pc. Any other way to make a backup from this laptop? Thanks

    Yes, I realized that it is a UEFI bios. Will this kind of bios be moddable with the Phoenix tool to have a slic 2.1? Or is it too dangerous to mess up with this kind of new bios? Thanks again.
    Edit: I also realized that there are 2 files that can be modded with the Phoenix tool when I decompress the exe file. One is P02ABK.cap (6.145 Kb) and the other is FvRecovery.fd (2.688 Kb). I suppose I should modd the first one, but what is the second one for? Should I used the Dynamic method (that's the default method when I try to modd P02ABK.cap). It's the first time I'll use that method, and I know it could be a little dangerous.

    Samsung's Phoenix EFI modding is little tricky. You have to modify P02ABK.cap; but it's not an one-click method. Let Serg008 do it for you or ask him for a tutorial.

    I feel really stupid right now. The bios already had a 2.1 slic table. I didn't know because I couldn't check it with the slic toolkit, but after I disabled secure boot, enabled csm and disabled fast bios, I could boot to my Windows 7 usb disk. Then, I checked for slic table, and 2.1 was there. The Samsung certificate that I had matched it, so now I have an activated copy of Windows 7. Thanks for your help.
