lspci -v

00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02)
	Subsystem: Dell Device 01da
	Flags: bus master, fast devsel, latency 0, IRQ 2300
	Memory at dfe00000 (32-bit, non-prefetchable) [size=1M]
	Memory at c0000000 (64-bit, prefetchable) [size=256M]
	I/O ports at ecb8 [size=8]
	Capabilities: <access denied>

Is this the right info?

If I've read the rest of them correctly I would think it would be:

sudo -s
echo "base=0xc0000000 size=0x10000000 type=write-combining" > /proc/mtrr

but it gives me the message:

root at ubuntuServer:~# echo "base=0xc0000000 size=0x10000000 type=write-combining" > /proc/mtrr
bash: echo: write error: Invalid argument
root at ubuntuServer:~#
