Hi, Thank you very much. But do I have to find exact Red Hat 9.x? Can
Fedora Core do the same work of Red Hat 9.x? Seems Red Hat is not free
any more? I can find a free Mandrake (www.linuxiso.org) which is
mentioned on that software distribution platform list
(http://software.sci.utah.edu). But I was told I am better off using
Redhat and then was given this fedora link.
