Up to eight ISA (or EISA) modules can reside in the EISA bus portion of the card
cage. Refer to Section 5.6 for information on using the EISA Configuration Utility
(ECU) to configure ISA options.
Warning: For protection against fire, only modules with current-
limited outputs should be used.
5.5.1 Identifying ISA and EISA options
By examining the contacts of the option board you can determine whether a board
is EISA or ISA (Figure 5–5):
• ISA boards have one row of contacts and no more than one gap.
• EISA boards have two interlocking rows of contacts with several gaps.

5.6 EISA Configuration Utility
Whenever you add, remove, or move an EISA or ISA board in the system, you
will need to run a utility called the EISA Configuration Utility (ECU). Each EISA
or ISA board has a corresponding configuration (CFG) file, which describes the
characteristics and the system resources required for that option. The ECU uses
the CFG file to create a conflict-free configuration. The ECU is a menu-based
utility that provides online help to guide you through the configuration process.
The ECU is run from the ARC menu interface.
