EISA Board Conﬁguration

Troubleshooting E/ISA Board Conﬁguration

Step 3. If you added the board interactively, did you save the new conﬁguration

before exiting eisa_config? If not, run eisa_config again, add the

board again, and then save the conﬁguration. See "Saving the

Conﬁguration and Exiting eisa_conﬁg."

Did you change any switch and jumper settings to match the settings

speciﬁed in /etc/eisa/config.log? If so, verify that you did so

accurately.

Step 4. Did you reboot the system after changing the conﬁguration interactively?

If not, reboot the system, taking care to warn users ﬁrst.

Step 5. Did you create the necessary device special ﬁles correctly? For

HP-supplied boards, insf will have created the necessary device special

ﬁles for any attached devices on rebooting. For boards supplied by a

different manufacturer, refer to the documentation shipped with your

board. If the driver is not known to insf, use mknod to create any

required device special ﬁles.

Board Conﬁguration Conﬂicts

E/ISA boards use four types of resources: interrupt lines, DMA channels,

cannot conﬁgure a board due to resource conﬂicts, you may still be able

to use eisa_config interactively to add a board that had a conﬂict or to

change choices for a new board. Refer to “Changing Choices for Board

Functions”.

If your desired board conﬁguration still causes conﬂicts, you may not be

able to use certain boards together. Some conﬁgurations are simply not

possible; for example, two boards from different manufacturers may both

require the same resource. If this happens, only one of the boards can be

used.

Two CFG Files Have the Same Name

If you want to load a CFG ﬁle into the /sbin/lib/eisa directory that has

the same name as a ﬁle already in that directory, follow these steps:

Step 1. Load the new CFG ﬁle from media into a temporary directory.

Step 2. Rename the CFG ﬁle, using the same syntax as described in “E/ISA

Boards and CFG Files”, at the beginning of this appendix. In the

temporary directory, type the following command:
