Configuring the Software Required by the
E/ISA Board
You install an E/ISA interface board much like installing any other
board, by following the procedures detailed in Chapter 3, “Configuring
Interface Cards.”
However, several additional software elements need to be present for
proper configuration:
•ACFG file must reside in the /sbin/lib/eisa directory for every
EISA board.
• The eisa interface driver must be part of the kernel before you can
run eisa_config for all (HP and other) E/ISA boards.
If you are configuring a board by a different manufacturer, the
manufacturer must provide a device driver for the board, information for
a CFG file, and any additional information required to create valid device
files.
In addition to the eisa driver, the interface driver used by the specific
card (such as SCSI or LAN) must also be part of the kernel. If you are
connecting a peripheral device (such as a printer or tape drive) to the
card, the peripheral's device driver must be part of the kernel. The
interface and device drivers can be added at the same time, thus
enabling you to regenerate the kernel and reboot your system only once.
In the simplest case, when you reboot, eisa_config runs and
automatically configures your E/ISA cards, based on the switch settings
or information it finds in the CFG files.
In more complex cases, eisa_config runs and discovers configuration
conflicts, requiring you to set switches and jumpers on the board, or to
run the command in interactive mode to resolve the conflicts. (See
sections further in this chapter and eisa_config (1M) in the HP-UX
Reference, and the on-line help within the eisa_config program.)
