Help: DOS formatted ZIP disks in OS X (10.2.6)

I have several DOS formatted zip disks (zip-100) that are not read in
OS X. They are read perfectly well when I reboot the computer in 9.2.2.

My Mac formatted zip disks are read in OS X. I do have the most recent
version of Iomega zip tools for OS X loaded.

What do I need to do to get OS X to recognize and read a DOS formatted
zip disk?

Thank you,
Bev
