Disabling a device in the Configuration Menu (for example, Serial port B in the diagram above) has the advantage of freeing the resources (such as IRQs and peripheral addresses). Disabling a device in the Security Menu disables the access, not the device. It does not have the advantage of freeing the resources, but has the advantage of temporarily disabling the device without losing the configuration settings.

The USB interface field, in the USB Devices sub-menu, is disabled by default.

The Modem IRQ field, in the Modem sub-menu, is used when a modem accessory has been installed. It does not enable the IRQ on the modem. It is used to indicate, to the System BIOS, which of the IRQ lines should wake up the PC when the modem receives a ringing tone. It is only applicable with an APM 1.2 compatible operating system, such as Windows 95.
