I had exactly the same problem on a machine, yesterday, using a 3com 905x card. I
solved it by moving it to a 'higher' pci slot. The previous pci slot was 'shared'
with isa, and from my exprience, this slot often causes problems with network
cards. Check to see if your nic is in a 'shared' slot. If your card is new and
installs properly, spending time doing diagnostics may not help if the hardware
doesn't like the configuration. In fact, in my case, the Windows98 boot up became
much faster and smoother after the slot change. HTH.
