|
---|
6 | <para>If you have an Intel P6 (Pentium Pro, Pentium II and later) it is recommended
|
---|
7 | that you compile <acronym>MTRR</acronym> (Memory Type Range Registers) support into the kernel.
|
---|
8 | The kernel can map Cyrix and AMD <acronym>CPU</acronym>s to the
|
---|
9 | <acronym>MTRR</acronym> interface so selecting this
|
---|
10 | option is useful for those processors also.
|
---|
11 | This option is found in the
|
---|
12 | "Processor type and features" menu. It can increase performance of
|
---|
13 | image write operations 2.5 times or more on <acronym>PCI</acronym> or
|
---|
14 | <acronym>AGP</acronym> video cards.</para>
|
---|
15 |
|
---|
16 | <para>In the "Character Devices" section, enable <acronym>AGP</acronym> Support and select the chipset
|
---|
17 | support on your motherboard. If you do not know the chipset, you may select
|
---|
18 | all the chip types at the expense of extra kernel size. You can usually
|
---|
19 | determine your motherboard's chipset by doing:</para>

24 | (<acronym>DRI</acronym>)

---|
25 | supported video card. A complete list of <acronym>DRI</acronym> supported video cards can
|
---|
26 | be found at <ulink url="http://dri.sourceforge.net" /> in the Status section.
|
---|
27 | Currently,
|
---|
28 | supported cards include those from 3dfx (Voodoo, Banshee), 3Dlabs,
|
---|
29 | ATI (Rage Pro, Rage 128,
|
---|
30 | Radeon 7X00, Radeon 2), Intel (i810, i815), and Matrox (G200, G400, G450).
|
---|
31 | Additionally NVidia provides their own closed source binary drivers.
|
---|
32 | If you do enable <acronym>DRI</acronym> here, make sure you select the video card(s) you want
|
---|
33 | to support as a <emphasis>module</emphasis>.</para>
