PCI, Plug n' Play, and Interrupt/DMA Assignments
• Plug and Play
♦
PnP BIOS – [Disabled] or [Enabled]
∗ If this field is set to [Enabled], the BIOS uses Plug and Play adapter initialization and assigns
the resources, such as I/O addresses, IRQs, and DMA channels to Plug and Play compatible
devices. The resources assigned by the BIOS are based on the settings of the IRQ and DMA
channel assignments listed in the following fields.
∗ If this field is set to [Disabled], the IRQs and DMA channels listed below can not be assigned
to Plug and Play devices.
♦
PnP OS – [Disabled] or [Enabled]
∗ If this field is set to [Enabled], the BIOS makes the Plug and Play API available for Plug and
Play Operating Systems. This allows the Plug and Play OS to get the Plug and Play
information by calling the Plug and Play API.
♦
Assign IRQ 1 – [Disabled] or [Enabled]
∗ If this field is set to [Enabled], then the BIOS can assign this IRQ to a Plug and Play adapter.
∗ If another device in the system is using this IRQ, then this field should be set to [Disabled].
♦
Assign IRQ 3 – [Disabled] or [Enabled] (Typically COM2)
∗ If this field is set to [Enabled], then the BIOS can assign this IRQ to a Plug and Play adapter.
∗ If another device in the system is using this IRQ, then this field should be set to [Disabled].
