If you have an Intel P6 (Pentium Pro, Pentium II and later) it is recommneded that you compile MTRR (Memory Type Range Registers) support into the kernel. The kernel can map Cyrix and AMD CPUs to the MTRR interface so selecting this option is useful for those processors also. This option is found in the "Processor type and features" menu. It can increase performance of image write operations 2.5 times or more on PCI or AGP video cards. In the "Character Devices" section, enable AGP Support and select the chipset support on your motherboard. If you do not know the chipset, you may select all the chip types at the expense of extra kernel size. You can usually determine your motherboard's chipset by doing: cat /proc/pci In the "Character Devices" section, disable Direct Rendering Manager unless you have a Direct Rendering Infrastructure (DRI) supported video card. A complete list of DRI supported video cards can be found at in the Status section. Currently, supported cards include those from 3dfx (Voodoo, Banshee), 3Dlabs, ATI (Rage Pro, Rage 128, Radeon 7X00, Radeon 2), Intel (i810, i815), and Matrox (G200, G400, G450). Additionally NVidia provides their own closed source binary drivers. If you do enable DRI here, make sure you select the video card(s) you want to support as a module. If you made any changes to the kernel configuration, recompile with make dep && make bzImage && make modules && make modules_install Copy /usr/src/linux/arch/i386/boot/bzImage and /usr/src/linux/System.map to /boot, edit /etc/lilo.conf appropriately and run lilo. If you use grub, edit /boot/grub/grub.conf and add the new kernel to the boot menu. If you build XFree86 in a chroot environment, make sure the kernel version of the base system and the target system are the same. This is especially important if you enabled DRI support as a module as instructed above. Although XFree86 will compile without a host.def file, the following file is recommended for customizing the installation. Start from the xc directory. cat > config/cf/host.def << "EOF" /* Begin XFree86 host.def file */ /* System Related Information.

Do do this, perform the following: cd programs/Xserver/hw/xfree86/os-support/linux/drm/kernel && make -f Makefile.linux && mkdir -p /lib/modules/`uname -r`/kernel/drivers/char/drm/ && cp gamma.o radeon.o sis.o r128.o i810.o i830.o mga.o tdfx.o \ /lib/modules/`uname -r`/kernel/drivers/char/drm/ && depmod -a If you recompile or updrade your kernel, you will need to re-copy the driver modules to the kernel module library and rerun depmod.
