• DMA Channel 1 – [Available] or [Reserved]
∗ If [Available] is selected, the BIOS can assign this DMA Channel to a PCI/PnP device.
∗ If [Reserved] is selected, the BIOS holds this DMA Channel for a legacy ISA device.
• DMA Channel 3 – [Available] or [Reserved]
∗ If [Available] is selected, the BIOS can assign this DMA Channel to a PCI/PnP device.
∗ If [Reserved] is selected, the BIOS holds this DMA Channel for a legacy ISA device.
• DMA Channel 5 – [Available] or [Reserved]
∗ If [Available] is selected, the BIOS can assign this DMA Channel to a PCI/PnP device.
∗ If [Reserved] is selected, the BIOS holds this DMA Channel for a legacy ISA device.
• DMA Channel 6 – [Available] or [Reserved]
∗ If [Available] is selected, the BIOS can assign this DMA Channel to a PCI/PnP device.
∗ If [Reserved] is selected, the BIOS holds this DMA Channel for a legacy ISA device.
• DMA Channel 7 – [Available] or [Reserved]
∗ If [Available] is selected, the BIOS can assign this DMA Channel to a PCI/PnP device.
∗ If [Reserved] is selected, the BIOS holds this DMA Channel for a legacy ISA device.
• Reserved Memory – [Disabled], [16k], [32k], or [64k]
∗ If [Disabled] is selected, the BIOS is prevented from reserving memory for ISA devices.
∗ If [64k] is selected, the BIOS reserves 64k of system memory for ISA devices.
• PCI Slot 1 – IRQ Preference– [Auto], [3], [4], [5], [7], [9], [10], [11], [12], [14], or [15]
These fields select the PCI slot IRQ preference.
• PCI Slot 2 – IRQ Preference– [Auto], [3], [4], [5], [7], [9], [10], [11], [12], [14], or [15]
• PCI Slot 3 – IRQ Preference– [Auto], [3], [4], [5], [7], [9], [10], [11], [12], [14], or [15]
• PCI Slot 4 – IRQ Preference– [Auto], [3], [4], [5], [7], [9], [10], [11], [12], [14], or [15]
NOTE Manually selecting IRQs for the PCI slots does not guarantee the PCI
slot device will be configured with the selection. Typically, Plug &
Play ISA cards (if present ) are assigned the available resources
before PCI devices.
