hi mate there is an very simply solution can slove this problem even you don't have disk 5. Just use original disk1 and 2, 3 to make a default install the system which shoudl no need disk 5. then switch the install media from cd-rom to ftp the ftp address can be use like ftp://ftp.suse.com user name and pwd anonmyous then you can install this without CD-rom cheers
