Thanks for your reply, Appleman. Unfortunately, I didn't understand a word of it.
My problem is that I'm a user and not a programmer, so even though I've seen posts here and there that may have solutions for me, they often explain concepts that I can't wrap my head around because I don't understand the syntax, etc. of Linux. I just want to jump in there, install a system, make it look the way I want, with software I want to use, and get to work (or play).
It's sort of a catch 22 for me. I want to learn more about Linux, but I can't until I can install and run it.
I saw that SLAX has a CD image that they created and you can download. "SLAX Boot CD is used to boot SLAX from USB devices on computers which can't boot from USB directly. It can be also used to boot SLAX from ISO file on disk."

But I don't want to spend time with working with distributions that I don't plan on using in the long run.
I've also found these tutorials online, but I don't know enough about Linux to follow them:
My hope is that the community of Sabayon developers will be able to provide a CDROM image of a disk that will find an installation on a partition of an external USB drive and boot into that.
Thanks for your help.
