Appendix A EISA Board Configuration

Table of Contents

Before you can make use of EISA and ISA I/O boards on Hewlett-Packard workstations, you must configure them using the /sbin/eisa_config program. eisa_config allocates resources (such as interrrupt lines, memory, and DMA channels) to all the boards on the E/ISA backplane, by reading the boards' corresponding CFG files.

Depending on the type of board, you run eisa_config in one of two modes:

automatic mode, which executes automatically each time you reboot the system. EISA boards can usually be configured automatically.
interactive mode, which you can execute from the command line. ISA boards require that you run eisa_config in interactive mode.

This appendix covers

A sample eisa_config session to add an E/ISA board.
Procedures for moving and removing an E/ISA board, as well as changing choices for board functions.
Troubleshooting E/ISA board configuration problems.

For further discussion of E/ISA specifications, see eisa_config(1M) in the HP-UX Reference. If you are configuring a custom driver or writing your own device driver, refer to HP-UX Driver Development Guide (part number 98577-90001) and HP-UX Driver Development Reference (part number 98577-90602).
