In order to install Slackware Linux from a CD-ROM, it must 
contain the distribution arranged beneath a source directory
in the same way as if you were to install it from a hard 
drive or NFS. The source directory must contain subdirectories
for each floppy disk. Your CD-ROM should be compatible with 
this format if it contains a mirror of the Slackware FTP site. 

What type of CD-ROM drive do you have?
