Appendix A 233
EISA Board Configuration
A EISA Board Configuration
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
interrupt 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).
