If you decide to use a separate VGA monitor as your boot
monitor, you must disable the BarcoMed Nio’s on-board VGA
capabilities by moving the jumper to the bottom two pins.
Caution: To use multiple BarcoMed Nio controllers in a single host
with VGA enabled, you should enable VGA on only ONE of the
BarcoMed Nio display controllers and disable VGA on ALL the
other BarcoMed Nio display controllers.
Examples of PCI slots
Although the BarcoMed Nio is a 64-bit board, it may be installed
in either a 64-bit or 32-bit PCI slot. However, installing it in a
32-bit PCI slot will result in a decrease in performance. Figure 5
on page 25 illustrates the types of slots so that you can correctly
identify which one to use for the BarcoMed Nio.
