Download clean versions of the distribution and the patch file for OpenRISC 1000 from the locations given in Section 2.3. The recommended patch file comes from the MOF website. It is identical in content to the patch file which can be found on the OpenCores website, but is compressed, which saves bandwidth.

	Important
	Ensure the version number of the distribution (3.4.4) is exactly the same.

Unpack the downloaded source code and apply the patch file (See Section 3.1.1 for an example of how to apply a patch file.).
