P4TBA BIOS Setup Onboard Serial Port2 Select an address and corresponding interrupt for the first and second serial ports. The Choices: 2F8/IRQ3 (default), 3F8/IRQ4, , 3E8/IRQ4, 2E8/IRQ3, Disabled Auto. UART Mode Select This item allows you to determine which Infra Red (IR) function of onboard I/O chip. The Choices: Normal (default), ASKIR, IrDA. UR2 Duplex Mode Select the value required by the IR device connected to the IR port. Full-duplex mode permits simultaneous two-direction transmission. Half-duplex mode permits transmission in one direction only at a time. The Choices: Half (default), Full. Onboard Parallel Port This item allows you to determine access onboard parallel port controller with which I/O address. The Choices: 378/IRQ7 (default), 278/IRQ5, 3BC/IRQ7, Disabled.

PWRON After PWR-Fail This field determines the action the system will automatically take when power is restored to a system that had lost power previously without any subsequent manual intervention. There are 3 sources that provide current to the CMOS area that retains these Power-On instructions; the motherboard battery (3V), the Power Supply (5VSB), and the Power Supply (3.3V). While AC is not supplying power, the motherboard uses the motherboard battery (3V). If AC power is supplied and the Power Supply is not turned on, 5VSB from the Power Supply is used. When the Power Supply is eventually turned on 3.3V from the Power Supply will be used. There are 3 options: "Former-Sts", "On", "Off". "Former-Sts" Means to maintain the last status of the CMOS when AC 18
