    Hi All

    Does anyone know what the deal is with the new AMI bios releases from Asus? They have an OEMX table, which is actually the SLIC table (176h). This tables OEM ID is AMI and OEM Table ID is OEMXLIC. Editing the usual way does not work anymore (i.e. extract 1B module with MMTool search SLIC text and replace with the 374 bytes from Asus SLIC.bin, search RSDT and XSDT and replace with _ASUS_ and Notebook respectively). Doing all this still results in no SLIC table appearing as it usually did with the older BIOS revisions. The RSDT is updated correctly with _ASUS_ and Notebook in ACPIScope, but no SLIC!! how annoying! I can write the SLIC over the OEMX table with RWEverything and then Vista is activated, but it's not a permanent fix. The automatic AMI mod tools work, but the OEMX table seems to be the official way/place SLIC is supposed to be.

    Anyone know how to defeat this new method?

    And simply replacing OEMX table in 1B module with SLIC is not the answer because system will not POST in that case!

    Cheers

    Please post a link to such a bios. It's known that Asus uses a configuration lock at 1b module! The first generation of it was cracked, the second one not yet. Is there a third one? So a dynamic allocation of SLIC is not possible for months

    Anyway it doesn't prevent the SSV3 modding way.

    AFAIK your bios has got the first generation of lock (canot test right now)

    How to crack first generation config lock:

    Locate at 1B module:
    Byte sequence 2E8A073C007431, change it to 2E8A073C007421
    Any error message?

    Don't forget you have to flash such a mod (FC-mod) like:
    Afudos /ixxxx.rom /pbnc /n

    amioemslic was written by Gkend and tries to introduce a dynamically allocated SLIC
    ASUS_AMI-FC10 and ami_SLIC3 by Zhaoliang. ASUS_AMI-FC10 cracks the first generation of lock and replaces the FC module with SLIC data.
    ami_SLIC3 will work for sure, but you'll get a super static mod.

    BTW: Official OEM's are now using super static addressing as well:D

    Are you familiar with IDA pro?

    You may crack the second generation of config lock, if you want ;)

    Actually I don't have that sequence.

    I have
    2E8A073C007406 and 2E8A073C00741A but not 2E8A073C007431
    just under System Configuration, System Lock and System version strings.

    If u can send me a link of bios with this string, I can find corresponding string and pos in mine. And therefore I'll see which bytes we'll seek with JNZ instruction.

    I flashed just with /i flag. I missed "/pbnc /n" part.

    I don't remember ;) It was a friend's computer. And I won't have access in 2 days.

    Oh yes. The FC tool isn't working for your bios, since it has got the next generation of lock already.

    Have a look here:
    http://forums.mydigitallife.net/threads/378?page=37

    If you want a bios to check with first generation of lock, get Asus P5B deluxe bios 1212 from Asus website.

    It would be great if you are able to remove the next genaration of lock.
