It's in your BIOS (cs=0xc800)

00000000  2E0F011E1D11      lidt [cs:0x111d]
00000006  2E0F01162311      lgdt [cs:0x1123]
0000000C  0F20C0            mov eax,cr0
0000000F  6625FFFFFF7F      and eax,0x7fffffff
00000015  0C01              or al,0x1
00000017  0F22C0            mov cr0,eax
0000001A  EB00              jmp short 0x1c
0000001C  0F01E0            smsw ax

Your BIOS is trying to enter protected mode.  Try turning off support
for DMA in your BIOS.
