unable to find a root hard disk

Hey,I'm new with Unixware.

Lately,I worked with Unixware7.1.3.I ran into problems while installing it.The problem is :

Error:unable to find a root hard disk...

Well,I have a HBA floppy disk,but my pc has no floppy driver.Is there any way to solve the problem with USB driver?What should I do?

Any help will be appreciated.

Regards,Dorr

Our last server had not floppy, so I burnt them to a CD. Bit of a waste puting 1M on a CD but, they are cheaper than floppy disks nowadays
