Thank you for replying my posts. In fact, I don't know whether the software supports the SCO OpenServer 5.0.5. I have
the CD-ROM, but no UNIX CD. I downloaded the virtuial CD image file(*.iso) through the Internet, just planned to install it
under MS-Windows(I don't want dual-boot). But I think if the problem detecting CD-ROM is hard to solve, I can use floppy to
instead. But with the software virtual PC, I need the image file(*.vfd). I don't have the UNIX enviornment to build an boot floppy, so I am seeking the downloads. Where can I d/l it?
