Device Records
Installed Device Records
Use the following tables to keep a record of the options installed in
or attached to your system. You can also record your system's
default configuration settings. This information can be helpful when
you install additional options in your PC Server 704 or if you ever
need to have your server serviced. It is recommended that you
copy these tables before recording information in them, in case you
need extra space to write new values later, when you update your
system's configuration. Table 8 on page 281 lists the default values
for configuration choices in the System Configuration Utility
program.
Note: If necessary, you can also refer to the system-board layout in
“The System Board” on page 288 for connector locations.
