As I said earlier, I have a similar board and this is what I got:
int=0000000d err=00000000 efl=00030002 eip=000001b1
eax=00000011 ebx=00000002 ecx=00009d82 edx=0009dbc8
esi=000003f0 edi=00000368 ebp=000003a8 esp=00000362
cs=cf00 ds=0040 es=1400 fs=0000 gs=0000 ss=9d82
cs:eip=2e 0f 01 16 7d 00 0f 20-c0 0c 01 0f 22 c0 eb 00
b8 08 00 8e d8 8e c0 8e-d0 66 2e a1 54 00 66 8b
ss:esp=3f 00 c0 96 00 00 11 00-00 00 00 14 40 00 02 2f
46 00 02 00 00 00 f0 03-00 00 a8 03 00 00 94 03
The following is the disassembled code:
0: 2e 0f 01 16 lgdtl %cs:(%esi)
4: 7d 00 jge 0x6
6: 0f 20 c0 mov %cr0,%eax
9: 0c 01 or $0x1,%al
b: 0f 22 c0 mov %eax,%cr0
e: eb 00 jmp 0x10
10: b8 08 00 8e d8 mov $0xd88e0008,%eax
15: 8e c0 mov %eax,%es
17: 8e d0 mov %eax,%ss
19: 66 2e a1 54 00 66 8b mov %cs:0x8b660054,%ax
