IRQ12, most likely conflict Mouse Port or PS/2 Mouse
These types of mice are supported by Windows NT through the
I8042PRT.SYS driver. The mouse usually has a (small) cylindric 6 pin con-
nector. It seems that these types of mice mostly will use IRQ12. The Win-
cor Nixdorf PCD product line e. g. is delivered with this type of mouse.
Some systems allow to disable the mouse port in the BIOS Setup, e.g.
those of the Wincor Nixdorf PCD product line.
IRQ15, most likely conflict IDE controller
Many motherboards of the Pentium class dispose of an IDE controller,
which uses IRQ14 for the primary IDE controller (1st channel) and IRQ15
for the secondary IDE controller (2nd channel). A conflict may arise with
the IRQ15 if the secondary IDE is set to “enabled” in the BIOS
setup, e.g. because the BEETLE system is equipped with a CD ROM
drive. Thus the IRQ15 can not be used by other controllers or functions,
e.g. by an AT COM board.
If the secondary IDE is set to “disabled” in the BIOS setup, the IRQ15
is available and can be used by other controllers/functions, e.g. by an
AT COMboard.
Adding COM ports under Windows NT
To add a COM port to your system configuration, run the Control Panel
from the Program Manager. Click on the Ports icon and then on the Add
button to make a new COM port known to the system. Then enter IRQ and
hardware address according to the jumper configuration you set before.
See sections 3 and 4 for details about setting the jumpers.
Adding COM ports under Windows 9x
To add a COM port to your system configuration, run the “Add New Hard-
ware” wizard. It is not recommendable to run the automatic hardware de-
tection! Add the new COM port explicitly instead. It would get some
(presumably wrong) port address and IRQ. Change these according to the
jumper configuration you set before. See the sections 3 and 4 for details
about setting the jumpers. After having made these changes to the Win-
dows 9x configuration, you will have to reboot the system, before they can
get into effect. It is not recommended, however, to reboot before having
entered the port address and IRQ correctly.
