/proc/mtrr
This file refers to the current Memory Type Range Registers (MTRRs) in use with the system. If
the system architecture supports MTRRs, then the
following:
reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1 reg01:
base=0xe8000000 (3712MB), size= 32MB: write-combining, count=1
MTRRs are used with the Intel P6 family of processors (Pentium II and higher) and control
processor access to memory ranges. When using a video card on a PCI or AGP bus, a properly
configured

Most of the time, this value is properly configured by default. More information on manually
configuring this file can be found locally at the following location:

/proc/partitions
This file contains partition block allocation information. A sampling of this file from a basic
system looks similar to the following:
