I didn't know this product was available but I went to the Connectix Company web-site and reviewed their product. I did not see where they supported SCO OpenServer 5.0.5 as a host. I did see where they supported Linux. I am not saying that you cannot run SCO Openserver as a host, just didn't see where the company supported it.
An alternative to loading the O/S via CD-ROM. You can load the images from the CD-ROM on a different machine that is networked to your Windows 2000 server and you can actually load the O/S via the network - TCP/IP. I think you can find detailed instructions from the SCO website on this.
