-It is VERY recommended to check if the MTRR registers
-are set up properly, because they can give a big performance boost.

-Do a <command>cat /proc/mtrr</command>:

-It's right, shows my Matrox G400 with 16MB memory. I did this from
-XFree 4.x.x, which sets up MTRR registers automatically.

-<para>
-If nothing worked, you have to do it manually. First, you have to find the
-base address. You have 3 ways to find it:
-
-<orderedlist>
-<listitem><para>
-  from X11 startup messages, for example:
-  <screen>
-(--) SVGA: PCI: Matrox MGA G400 AGP rev 4, Memory @ 0xd8000000, 0xd4000000
-(--) SVGA: Linear framebuffer at 0xD8000000<!--

-</para></listitem>

-  from <filename>/proc/pci</filename> (use <command>lspci -v</command>
-  command):
-  <screen>
-01:00.0 VGA compatible controller: Matrox Graphics, Inc.: Unknown device 0525
-Memory at d8000000 (32-bit, prefetchable)<!--
-  --></screen>
-</para></listitem>
-<listitem><para>
-  from mga_vid kernel driver messages (use <command>dmesg</command>):
-  <screen>mga_mem_base = d8000000</screen>
-</para></listitem>
-</orderedlist>
-</para>
-
-<para>
-Then let's find the memory size. This is very easy, just convert video RAM
-size to hexadecimal, or use this table:
-<informaltable frame="none">
-<tgroup cols="2">
-<tbody>
-  <row><entry>1 MB</entry><entry>0x100000</entry></row>
-  <row><entry>2 MB</entry><entry>0x200000</entry></row>
-  <row><entry>4 MB</entry><entry>0x400000</entry></row>
-  <row><entry>8 MB</entry><entry>0x800000</entry></row>
-  <row><entry>16 MB</entry><entry>0x1000000</entry></row>

-</tbody>
-</tgroup>
-</informaltable>
-</para>

-<para>
-You know base address and memory size, let's setup MTRR registers!
-For example, for the Matrox card above (<literal>base=0xd8000000</literal>)
-with 32MB ram (<literal>size=0x2000000</literal>) just execute:
-<screen>
-echo "base=0xd8000000 size=0x2000000 type=write-combining" &gt; /proc/mtrr
-</screen>
-</para>
-
-<para>
-Not all CPUs have MTRRs. For example older K6-2 (around 266MHz,
-stepping 0) CPUs don't have MTRRs, but stepping 12 does
-(execute <command>cat /proc/cpuinfo</command> to check it).
