>Super I/O Configuration
• Onboard Floppy Controller – [Disabled] or [Enabled]
• Serial Port 1 Address – [Disabled], [3F8/IRQ4], [2F8/IRQ3], [3E8/IRQ4], or [2E8/IRQ3]
• Serial Port 2 Address – [Disabled], [3F8/IRQ4], [2F8/IRQ3], [3E8/IRQ4], or [2E8/IRQ3]
♦ Serial Port 2 Mode – [Normal], [IrDA], or [ASK IR]
∗ If [IrDA] or [ASK IR] are selected, the following items appear on screen.
◊ IR I/O Pin select – [SINB/SOUTB] or [IRRX/IRTX]
◊ IR Duplex mode – [Half Duplex] or [Full Duplex]
• Parallel Port Address – [Disabled], [378], [278], or [3BC]
If [378], [278], or [3BC] are selected, the following items appear on screen.
♦ Parallel Port Mode – [Normal], [Bi-Directional], [ECP], [EPP], or [ECP + EPP]
∗ If [Normal] is selected, the standard parallel port mode is used. This is the default setting.
∗ If [Bi-Directional] is selected, the data is sent to and received from the parallel port.
∗ If [ECP] is selected, the following options are listed. The parallel port can be used with
devices adhering to the Extended Capabilities Port (ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5 Megabits per second. ECP also
provides symmetric bi-directional communication.
◊ ECP Mode DMA Channel – [DMA0], [DMA1], or [DMA3]
∗ If [EPP] is selected, the following options are listed. The parallel port can be used with
devices adhering to the Enhanced Parallel Port (EPP) specification. EPP uses the existing
parallel port signals to provide asymmetric bi-directional data transfer driven by the host
device.
◊ EPP version – [1.9] or [1.7
]
∗ If [ECP + EPP] is selected, the options for both are listed, with EPP options listed first.
♦ Parallel Port IRQ – [IRQ5] or [IRQ 7]
• OnBoard CIR Port – [Disabled], [3E0], or [2E0]
♦ CIR Port IRQ – [IRQ3], [IRQ4], [IRQ10], or [IRQ 11]
• Serial Port 3 – [Disabled], [3F8], [2F8], [3E8], [2E8], [2F0], or [2E0]
♦ Serial Port 3 IRQ – [IRQ4], [IRQ9], [IRQ10], or [IRQ 11]
♦ Select Serial Port 3 Type – [RS232] or [RS485]
• Serial Port 4 – [Disabled], [3F8], [2F8], [3E8], [2E8], [2F0], or [2E0]
♦ Serial Port 4 IRQ – [IRQ3], [IRQ9], [IRQ10], or [IRQ 11]
♦ Select Serial Port 4 Type – [RS232] or [RS485]
