The output found here is similar to contents of /etc/mtab, except that /proc/mount can be more
current.
The first column specifies the device that is mounted, with the second column revealing the mount-
point. The third column tells the filesystem type, and the fourth column tells you if it is mounted
read-only (ro) or read-write (rw). The fifth and sixth columns are dummy values designed to match
the format used in /etc/mtab.
4.2.23 /proc/mtrr
This file refers to the current Memory Type Range Registers (MTRRs) in use with the system. If your
system's architecture supports MTRRs, your mtrr might look something like this:
reg00: base=0x00000000 (
MTRRs are used with Intel P6 family of processors (Pentium Pro and higher), and they are used to
control processor access to memory ranges. When using a video card on a PCI or AGP bus, a properly
configured mtrr file can increase performance over 150%.
Most of the time, this value is properly configured for you. For more information on MTRRs and
manually configuring this file, please see http://web1.linuxhq.com/kernel/v2.3/doc/mtrr.txt.html.
4.2.24 /proc/partitions
For very detailed information on the various partitions currently available to the system,

Most of the information here is of little importance to most users, except for the following lines:
• major — The major number of the device with this partition. The major number in our example
(3) corresponds with the ide0 device in /proc/devices, letting us know the kind of device
driver used to interact with that partition.
• minor — The minor number of the device with this partition. This serves to separate the parti-
tions into different physical devices and relates to the number at the end of the name of the partition.
• #blocks — Lists the number of physical disk blocks contained in a particular partition.
