Embarassing NEWBIE Question

["Bryan K. Walton" <walton@berbee.com>]

Hi,
	Please forgive me for asking such an embarassing question:  I have
installed Debian 2.1 on my laptop and have struggled to correctly
configure X.  So I am now preparing to install XFree86 3.3.5 which I have
been told will fix my problem.  I have all of the XFree86 3.3.5 files
burned onto a CD-ROM.  I need to copy the files from the CD-ROM to a temp
directory on my /usr partition.  Can someone please tell me exactly
what I need to type in order to do this?  How do I get into the
CDROM directory and how do I make Debian copy everything from that
CDROM to /usr/temp (a subdirectory I created for this purpose)?  

Thanks!
Bryan
