The command worked, but it just increased the counter in /proc/mtrr. I just rebooted, and the counter has been reset. It now reads: reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1 reg02: base=0xd8000000 (3456MB), size= 64MB: write-combining, count=2 The counter for reg01 was the one being increased with each execution of the command with base 0xd0000000, as is to be expected I guess. :) > Could you write what the morphix mtrr settings are, please? reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=2 As you can see: no reg02, and reg01 has its counter set to 2. Perhaps this has something to do with things?
