Configuring Expansion Boards
Each time you add, remove, or relocate any EISA/ISA/PCI expansion board, you
need to run the SCU to identify their operating characteristics, server resource
requirements, and slot locations. Based on this information, the SCU will then
automatically assign the proper server resources to EISA expansion boards, enable
PCI boards, and inform you as to what jumper or switch settings need to be manually
set on ISA expansion boards to avoid resource conflicts.
The SCU identifies an expansion board’s operating characteristics and resource
requirements through Configuration (.CFG) files. These files contain main logic
board, EISA, PCI, and ISA expansion board vital characteristics and the server
resources they require for proper operation. Before configuring the server, copy the
CFG files (and overlays if applicable) supplied with the additional EISA expansion
boards to either the SCU directory on the hard disk drive or to the SCU diskette.
As an added feature, the SCU creates and stores all setup changes in a System
Configuration (.SCI) file. This file is automatically generated when the SCU runs.
Afterwards, this SCI file can be used on any DIGITAL Server that is identically
configured and can serve as a backup to the EISA configuration stored in NVRAM
memory.
Starting the SCU
The SCU is located on the ServerWORKS Quick Launch CD-ROM disc. The SCU
options are shown in Figure 2-1. If this is the first time using the SCU, it is
recommended that you select “Learn About Configuring your Computer” for detailed
information on using the SCU. If this is a subsequent session, refer to the
appropriate sections in this chapter to change the server’s configuration.
