OS Problem

[TheMagician]

I run win98, win2k, and winxp on a dual boot setup, each has a seperate logical partition. Recently I received my DSL modem and got that setup with a borrowed NIC. Everything was working fine. Now, I can't seem to boot into winxp or win2k, but I can still boot into win98. On the selection screen I freeze when I select win2k or winxp, but win98 works fine. Nothing that I could tell should have changed, but apparantly something has. Is there a way to recover from this from within win98 in any shape or form?

Thanks
