2-1 Mounting a Board
2-1-1 Confirmation
Before you mount a CompoNet Master Board on the PC, confirm the
following:
Note CompoNet Master Boards support Windows Plug & Play.
Note
•
As for the procedures to call the BIOS menu and to set the allocation, see
the operation manual of the PC you are using.
•
You can confirm the IRQs that have been used by ISA bus in the following
procedure:
(1) Start up the PC that has no CompoNet Master Board mounted.
(2) On the Start menu of the Windows, select Start
→
Setting
→
Control Panel
from the pop-up menu. Double-click the System. Select the Hardware Tab.
Push the Device Manager button.
(3) Display the property of the ISA board whose IRQ is to be checked. Select
the Resource Tab and check the IRQ.
2-1-2 Setting the Board ID
A Board ID is the ID number given to a Board. By this number the PC
identifies a Board among the multiple CompoNet Master Boards mounted on
it.
A small, flat-blade screwdriver is used to set IDs.
As long as no duplication occurs, any decimal number among 0 and 9 can be
set.
Precautions for Correct Use
When you set the Board ID, be sure not to duplicate an ID for multiple
CompoNet Master Boards mounted on a single PC.
Item Description
Unused PCI bus slot Be sure that the PC you will use has an unused PCI bus slot.
Duplication of
interrupt requests
(IRQ) CompoNet Master Boards use IRQs. IRQ are automatically
allocated for PCI bus. In a PC which mounts an ISA bus, an
IRQ for PCI bus may overlaps with that for ISA bus. This
prevents the PC from starting up. To avoid this, take one of the
following measures and be sure the IRQ for PCI bus does not
overlap with the IRQ that has been used by the ISA bus.
⋅
Call up the BIOS menu of the PC and set it not to use Plug &
Play.
⋅
Call up the BIOS menu of the PC, and on the setting step for
IRQ allocation for the PCI bus set the IRQ that has been
used by ISA bus to “Reserved” to prevent automatic
allocation.
