Belkin KVM Switch and related OSs

Hello,
I'd like to share keyboard, monitor and mouse between my Apple Mac mini and an old PC in which there are two different OSs: Windows 98 SE and Ubuntu Linux. I had a look on the Web and found the Belkin KVM Switch for Mac mini. It should be exactly what I need, but looking at its technical data I noticed it's suitable for Mac OS X 10.3 and later (OK for me) and Windows 2000 or XP and no need of extra software.
Wondering if it could work with Windows 98 SE, as well, I contacted a MISCO Technician in Italy (they sell such Switch) who told me there should be a mistake in the technical data and it should work even with Windows 98 SE.
But now I'm a little doubtful and would be grateful to you if you let me know what you think about that (Am I supposed to buy it?).
Best Regards

a kvm switch should work on any os. we have a windows 2003 server, linux print server, and a unix syslog server, all on the same kvm switch.

EDIT: in fact, here is the one we have: http://www.newegg.com/Product/Produ...N82E16817107402
