 ## Building the Disk Image
 Creating a disk-image for SPEC 2006 requires the benchmark suite ISO file.

+More info about SPEC 2006 can be found <https://www.spec.org/cpu2006/>.
 
 In this tutorial, we assume that the file `CPU2006v1.0.1.iso` contains the SPEC
 benchmark suite, and we provide the scripts that are made specifically for
 SPEC 2006 version 1.0.1.
 Throughout the this document, the root folder is `src/spec-2006/`.
