NIFB Problems
When using the PCMCIA-FBUS card with Windows 2000/NT, Nifb
returns an error message stating that the board cannot be found.

This is probably due to a device address conflict. In the NI-FBUS Interface
Configuration utility, make sure that the interface is not at the same address
as anything else on the link. You also can temporarily give the interface
a visitor address to troubleshoot this problem.
The NIFB process hangs, does not start up, or never shows that it is

The card’s base memory address conflicts with another device. Try
using a different base memory address. Windows does not always
detect all conflicts. Even if Windows reports no conflicts, trying
a different address after you have eliminated the IRQ or Fieldbus
network address often will resolve the problem. You must restart
the machine each time you change base address and/or IRQ.
•
The card’s IRQ conflicts with another device. Try setting the card to
polled mode.
•
The Fieldbus network address is not unique. Remove the cable from
the card. Restart the NIFB process. If it runs successfully, there is
probably a Fieldbus network address conflict. If you have FP-3000
network modules on the bank, powering them off and then back on will
cause them to look on the bus for available addresses and change
