Pattern to find object manager

[karnkore]

Does anyone know a pattern to find the object manager ptr? I tried enigmas old post with this

BYTE ObjectManagerPtrPattern[]
{
0x8B, 0x00, 0x00, 0x00, 0x00, 0x00,
0xC7, 0x00, 0x00, 0x03, 0x00, 0x00, 0xFF, 0xFF, 0xFF, 0xFF
};

But it does not seem to find the correct offset. I just started looking into diablo so I don't have any old data to compare to, would like to get this pattern working since the other offsets are easier to work with.
