Asus P5PL2-E Core2 Quad Q6700 Support

Hi Guys,

I have an Asus P5PL2-E motherboard with bios version 1002 (last ever) without Core2 Quad CPU Support
Recently I have found that it is possible to run a Core2 Quad Q6700 on it
So I went for it and bought one
I have installed the Core 2 Quad Q6700 and it completely works and boots into OS.
The problem is the motherboard only detects 3 cores of the cpu instead of all four (both in the bios and os it shows 3 for the number of cores)
and when booting, bios shows: Intel CPU uCode loading error
Is it possible to add full support by adding microcode or doing something else?
