Help to UNLOCK Aopen DE3100 EM64T
#1
Hi guys!
Sorry, this is my first post... 
I just bought an Aopen DE3100, with Intel Atom D2550
I want to install a 64bit OS, but it states that the CPU does not support 64bit. So I digged around, and discovered that the CPU supports EMT64, but the vendor disabled it in BIOS.
Original BIOS is here:
.rom   DE3100.ROM (Size: 2 MB / Downloads: 17)


Does anybody know if there is an unlocked bios images around? 
If not, is it possible to mod the bios?

I've found there is someone already successed with asus's eepc,see this https://www.bios-mods.com/forum/Thread-R...eepc-1025C

Thank you in advance

I think I'm too late. But these are the places for the patch. In the same way, 3 is pushed in two places of MSR 0x122. Just try to analyze what you'd do, there more than one way to unlock em64t from this place. Find out what you'd need to nop out from these two places

this:-
0x001be69b and esi, 0xfffffff0 ; 4294967280
0x001be69e cmp esi, 0x30660
0x001be6a4 jne 0x1be6c6
0x001be6a6 cmp byte [var_1h], bl
0x001be6a9 je 0x1be6df
0x001be6ab mov esi, 0x122
0x001be6b0 push esi
0x001be6b1 call fcn.001c0821
0x001be6b6 or edx, ebx
0x001be6b8 push edx
0x001be6b9 or eax, 3
0x001be6bc push eax
0x001be6bd push esi
0x001be6be call fcn.001c0828
0x001be6c3 add esp, 0x10

and this:-
0x001bf2ef and eax, 0xfffffff0 ; 4294967280
0x001bf2f2 cmp eax, 0x30660
0x001bf2f7 jne 0x1bf314
0x001bf2f9 mov edi, 0x122
0x001bf2fe push edi
0x001bf2ff call fcn.001c0821
0x001bf304 or edx, esi
0x001bf306 push edx
0x001bf307 or eax, 3
0x001bf30a push eax
0x001bf30b push edi
0x001bf30c call fcn.001c0828
0x001bf311 add esp, 0x10
