burn iso image to cd-rom
burn the iso image (not the iso file) to a cd-rom and then reboot your computer to "boot" off the cd.
burning and booting from the cd-rom is the only 100% "true test" way to make sure that sgtxp is 100% capable of accurately detecting and working with your network card, raid drives, sata drives, etc.
if you don't have any cd-rom burning software, try deepburner free or iso recorder (aka iso power toy).
you will need to open the image (iso file) in deepburner free or iso recorder and then burn it's contents to your cd-rom drive.
you do not want to end up with just the iso file on the cd-rom because that will not work at all.
