Step-by-Step Guide

1. Download the ISO image appropriate for your architecture from Downloads or below:

   Architecture	Downloads
   i386	iso md5
   x86_64	iso md5

2. Verify the md5 checksum by verifying the two lines output are the same when you run the command below (replace the filenames with that of the downloaded iso and md5). If they do no match then you may need to re-download the iso images:

   $ md5sum pS-Performance_Toolkit-FullInstall-3.X.iso;cat pS-Performance_Toolkit-FullInstall-3.X.iso.md5
   

3. Mount the ISO to a DVD or USB drive

   Note

   The Full Install ISO is generally too large to fit on current writable CDs
