Appendix H. PCI Installation Tips

PCI computers are designed to configure add-in cards automatically each time the
computer starts. Your PCI computer sets the I/O address and IRQ level for your
network adapter when the computer starts. These values cannot be changed by
IBM adapter software. If you experience a problem when the computer starts, you
might need to follow additional configuration steps.
On some computers, manual configuration is possible through the computer's PCI
BIOS setup utility. Refer to your computer documentation. You might need to verify
or change some BIOS settings.
Some common PCI solutions are listed here.
