I have a problem with Acer Asipre One 531 (ZG8_3113.fd BIOS file). I cannot activate Win7 Enterprise with KMS server due to wrong SLIC table. SLIC Dump ToolKit Reports SLIC format error, RSDT shows "ACER ACER" and this doesn't match PubKey/Marker section. I also tried to remove SLIC from bios (removed 2 GUIDs in Insyde tool) bit still no luck - SLIC table still exists (but empty). What I need to change to pass SLIC data validation test in SLIC Dump ToolKit? How to change this "ACER ACER" RSDT field? I've decompressed and disasemmbled bios and found only 1 occurence of "ACER". seg000:00103850 sub_103850 proc near ; CODE XREF: sub_102774+2Bp seg000:00103850 ; sub_102774+210p seg000:00103850 seg000:00103850 arg_0 = dword ptr 4 seg000:00103850 arg_10 = dword ptr 14h seg000:00103850 seg000:00103850 mov eax, [esp+arg_10] seg000:00103854 mov cl, [eax] seg000:00103856 test cl, cl seg000:00103858 mov byte ptr [eax], 0 seg000:0010385B jnz short loc_10388A seg000:0010385D mov eax, [esp+arg_0] seg000:00103861 mov eax, [eax] seg000:00103863 cmp dword ptr [eax], 53434146h seg000:00103869 jz short loc_10388A seg000:0010386B mov ecx, 52454341h ; <-- this is "ACER" seg000:00103870 mov [eax+0Ah], ecx seg000:00103873 mov word ptr [eax+0Eh], 2020h seg000:00103879 mov [eax+10h], ecx seg000:0010387C mov dword ptr [eax+14h], 20202020h seg000:00103883 mov dword ptr [eax+1Ch], 35323031h seg000:0010388A seg000:0010388A loc_10388A: ; CODE XREF: sub_103850+Bj seg000:0010388A ; sub_103850+19j seg000:0010388A xor eax, eax seg000:0010388C retn seg000:0010388C sub_103850 endp
