When you download a ".iso" file from the web, you need a burner
program to handle that. The burner program must know how to
parse an ISO9660 file, and make a bootable CD from it. Nero is a
program that knows how to do that. If you want a free program,
You can't just copy the .iso file to a CD in Windows, as then the
CD won't be bootable. The .iso file not only contains a file system,
it also contains the information to prepare the part of the CD that
The reason memtest is a self-booting piece of media, is so that
there is no operating system present during the test. When memtest
is booted using floppy, CD, or USB flash stick, basically the
computer bootstraps itself using just the executable file provided
by the memtest developer. None of the other trappings of an OS
are present. Video cards have standard VESA modes that they support
and basic frame buffering capabilities. A program like memtest
should be able to display a 640x480 screen on most computers, using
those basic facilities. It is adherence to some hardware standards,
that makes it possible for a small program like that, to run all by
itself, without an OS to help.
Since there is no OS, there is no space wasted to hold an OS.
Almost all the memory in the computer is testable as a result.
Only 1MB of memory is reserved by the BIOS, and memtest pays
attention to any reservations signaled by the BIOS. It won't
write an area the BIOS is using.

Thanks again for very informative reply. I have already saved a few
of your responses (to other posts) in my 'Save These' folder, for
