    @andyp

    Im not sure (tryed it some days ago). But i would try it later next days.

    So with default Settings and only change "Only alter tables in the main ACPI module" or something else to?

    @LatinMcG

    Yes the BIOS is under the sticker. Now i have to wait for the USB-Flasher :)

    It's a "SST25VF080"

    Thanks

    I think either the bootblock is not being flashed normally and therefore contains the table ID or there is code that copies it from somewhere else that isn't flashed.
    I do wonder if flashing with a programmer will fix it. I will also look for a lock in the code (although I'm pretty rusty as I haven't looked for one for a couple of years!)

    Hi
    Normally this sort of lock is in BIOSCOD1.
    We know that the OEM ID is 6 bytes, the Table ID is 8 bytes and they start at Ah in the ACPI header, so I normally just disassemble in IDA and have an eyeball.
    I found:

    Code:
    seg000:C969 sub_C969        proc near               ; CODE XREF: seg000:C8B2p
    seg000:C969                                         ; sub_CE3D+16p ...
    seg000:C969                 push    ax
    seg000:C96A                 push    cx
    seg000:C96B                 push    esi
    seg000:C96D                 push    edi
    seg000:C96F                 mov     edi, esi
    seg000:C972                 add     edi, 0Ah
    seg000:C976                 mov     word ptr [edi], 'AM'
    seg000:C97B                 mov     word ptr [edi+2], 'BT'
    seg000:C981                 mov     word ptr [edi+4], 'OI'

    seg000:C993                 mov     word ptr [edi+2], ' I'

    seg000:C9B4
    seg000:C9B4 loc_C9B4:                               ; CODE XREF: sub_C969+5Cj

    seg000:C9BA                 jnz     short loc_C9BE
    seg000:C9BC                 mov     al, 20h ; ' '
    seg000:C9BE
    seg000:C9BE loc_C9BE:                               ; CODE XREF: sub_C969+51j
    seg000:C9BE                 mov     [edi], al
    seg000:C9C1                 inc     esi
    seg000:C9C3                 inc     edi
    seg000:C9C5                 loop    loc_C9B4
    seg000:C9C7                 pop     edi

    seg000:C9CD                 retn
    seg000:C9CD sub_C969        endp
    and patched it to (just nopped out the bits that actually write the OEM ID and the part of the loop that writes the Table ID:

    I'll incorporate it into the tool.
