Pardon a >real< newbie question . . .

[M. Rowen]

Hi Harvey,

   "iso" is short for ISO-9660 file system specification which is the
standard file system used to burn CD-ROMs. When you want to burn a CD,
you first create an ISO9660 image on your local disk and then you burn
that image onto your CD.

When you download an "iso" image, The data in the iso file can be burned
to a CD-ROM. Its important to realize that the image is a binary image
of what you want the CD-R to look like when it's burned. This is not the
same as copying the iso file to the CD-R. You want your CD burning
software to read from the iso image file and create a binary image of
it's contents. If you just treat the iso image like a file, what you end
up with on your CD is a copy if iso image file which isn't bootable or
anything other than a copy of the image itself.

I don't know if this helps or confuses you more.

Cheers,
-Mike
