reg01 is the area that should be used for the AGP apeture. So I disable it:
Code:
> cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1 reg01: base=0xe0000000 (3584MB), size= 256MB: write-combining, count=1
Code:
> echo "disable=1" >| /proc/mtrr > cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
Code:
echo "base=0xe0000000 size=0x10000000 type=uncachable" >! /proc/mtrr
