ISACFG Utility
Overview
ISA (industry-standard architecture) devices are not capable of being probed for
configuration information by the DEC OSF/1 or OpenVMS operating systems. Therefore,
you must enter ISA option information manually using the ISA configuration utility
(ISACFG). Run this utility before installing a new ISA option module on a Digital
AlphaStation system running either the DEC OSF/1 or OpenVMS operating system.
Prior to adding an ISA device, you must use an ISACFG to assign an IRQ to the device.
Make sure to leave enough IRQs unassigned to meet the needs of your PCI devices.

Refer to your AlphaStation system user information for details.
Command Format
The syntax of the ISACFG command is shown below:
