Installation Considerations
Newer adapters, designed for Plug-and-Play systems,
are automatically configured by the system without any
user intervention. Older ISA and EISA adapters must
be manually configured as detailed below. Once the
manual configuration is complete, the Plug-and-Play
adapters are configured around the manually
configured adapters without causing any resource
conflicts.
■
ISA Adapters - These adapters can be Plug-and-
Play. ISA adapters that are not Plug-and-Play must
be manually configured following the instructions
supplied with the board. The configuration is
defined to the system by creating the ISA
configuration file when running the SCU. For
details on running the SCU, refer to Chapter 4.
Note: The configuration files for boards supplied
with your server have already been included on the
SCU diskette.
■
EISA Adapters - Copy the configuration files
(.CFG) and, if supplied, the overlay file (.OVL), to
the SCU diskette. For details on running the SCU,
refer to Chapter 4.
Consider the following points when installing option
boards:
■
Any EISA slot can be a master or a slave.
■
EISA bus priority is slot P01 - P04, slot P01 having
the highest priority. EISA slot P01 is the bottom
option board slot on the system board. See Figure
5-11 for EISA slot numbers.
■
PCI bus priority is slot P05 - P10, slot P05 having
the highest priority. PCI slot P05 is the bottom PCI
option board slot on the system board. See Figure
5-11 for PCI slot numbers.
