CD-images of the system

[yellowdog-newbie@lists.terrasoftsolutions.com]

I downloaded what I thought was some kind of a CD image of an installing 
CD, from Yellowdog's pages. It was about 670 Mb. I burnt it on a CD and 
Thought it would work as a booting disc. But my computer (6500/250) 
doesn't recognise the disc. Well, it does, but there's just this 
meaningless file on the disc. I haven't done the partitions yet, needed 
for the Linux installation. I just wanted an assurance that the system 
will be installable from the CD that I burnt. 

I did the burning with a Windows machine. Is that the problem? The burner 
had no special ISO option, but the help file said that the burner uses 
the ISO standard. Obviously all the time.
