Verify that you have one disk with the Novell® Open Workgroup Suite Small Business Edition 2.5 installation files, or download the installation ISO from http://www.download.novell.com to a location of your choice and burn it to a DVD. The download is 5 GB. Download time depends on your hardware.
If you choose to download the installation ISO, be sure you utilize MD5 checksum to verify that the data is valid before you burn it to a DVD.
If you are using a VMware* session instead of a physical server, make sure to designate the boot sequence to boot from the CD-ROM.
