NVIDIA nForce/nForce2 AGPGART Linux Kernel Patch
================================================

NOTE: This patch only supports kernel 2.4.20.  You will need to either 
install kernel 2.4.20 and sources before patching, or manually merge
these changes to other kernel versions.

Patching the Kernel
-------------------

- Change to the Linux kernel source directory.

  Example: cd /usr/src/linux-2.4.20
  
- Patch the kernel. Watch out for any warnings or errors.

  patch -p1 < linux-2.4.20-agpgart.diff


Configuring the Kernel
----------------------

In order to use NVIDIA AGP chipset support, the kernel must be configured
accordingly.

- In the kernel source directory, run a kernel configuration tool such as
  menuconfig:

  make menuconfig

- In the 'Processor type and features', make sure that an x86 compatible CPU
  is selected.

- In the 'Character devices' section, select '/dev/agpgart (AGP Support)' as
  an included or modularized kernel feature.

- In the same section, enable 'NVIDIA chipset support'.


Rebuilding and Reinstalling the Kernel
--------------------------------------

Rebuild and reinstall the kernel and the kernel modules following the
appropriate procedure for your GNU/Linux distribution.
