Did the md5sum check...that worked great...thanks Rick.

Ok...here's where you're losing me guys.  When you record the iso image
using the above info, doesn't cdrecord (or any other CD burner software)
just burn one big file with a .iso extension?  I tried this with Gnome
toaster, got one file with the filename psyche-i386-disc1.iso...nothing
you could see any files with.  Does cdrecord take that command and pull
everything out of the .iso file?

I guess the question I have is, don't you have to use mkisofs to
separate out the files from the image so they can be viewed on any
platform?  I attempted to use mkisofs -r -o psyche-i386-disc1.iso per
instructions at the Linux newbie website...the hard drive spun for a
long time, then the cursor came back up on the command line...I couldnt
tell it did anything.  Now...is that command designed to MAKE iso images
or convert them back into files?  This is where my confusion is.  If I
put the disc I made with Gnome toaster in the cd drive and attempt to
look at it, it appears to have the same file on it that I have on the
hard drive.  Am I misunderstanding what a .iso file is?  Is it bootable
or does it need to be converted to the individual files within it...pull
the files out?

Am I making my confusion clear as mud?  LOL...you have to think like a
NEWBIE!  I've never done this before and maybe I'm not being clear where
my confusion about burning cd's from iso images is, but hopefully this
clears it up. 

Thanks again,

Wayne
