If you want polled mode, do not add the
irq specifier:
+ For FreeBSD 4.X, use the following line in
+ your kernel configuration file:
+
device ppc0 at isa?
+
+ For FreeBSD 5.X, simply remove in your
+ /boot/device.hints file, the
+ following line:
+
+ hint.ppc.0.irq="N"
+
+ In some cases, this is not enough to put the
+ port in polled mode under FreeBSD 5.X. Most of
+ time it comes from &man.acpi.4; driver, this latter
+ is able to probe and attach devices, and therefore,
+ control the access mode to the printer port. You
+ should check your &man.acpi.4; configuration to
+ correct this problem.
