AC97 Audio
Selecting Auto will enable the AC'97 audio if it is detected onboard.
Init Display First
This feature allows you to select whether to boot the system using the onboard AGP graphics
card or the PCI graphics card.
Onboard LAN 1/2 H/W Active
Enables and disables the onboard LAN modules.
Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the system
board and you wish to use it. If you install an add-in FDC or the system has no floppy drive,
select Disabled to this field.
Onboard Serial Ports (1, 2, 3, 4)
This feature allows you to manually select the I/O address and IRQ for the first and second
serial ports. It is recommended that you leave it as Auto so that the BIOS can select the best
settings for it. But if you need a particular I/O port or IRQ that's been taken up by this serial
port, you can manually select an alternative I/ O port or IRQ for it. You can also disable this
serial port if you do not need to use it. Doing so frees up the I/O port and IRQ used by this
serial port. Those resources can then be reallocated for other devices to use.
UART Mode Select
Select an operating mode for the serial port.
The choices are: Normal, IrDA, ASKIR.
UR2 Duplex Mode
In an infrared port mode, this field appears. Full-duplex mode permits simultaneous two-
direction transmission. Half-duplex mode permits transmission in one direction only at a time.
Select the value required by the IR device connected to the IR port.
Onboard Parallel Port
This feature allows you to select the I/O address and IRQ for the onboard parallel port. The
default I/O address of 378h and IRQ of 7 should work well in most cases. Unless you have a
problem with the parallel port, you should leave it at the default settings. The choices:
378/IRQ7, 278/IRQ5, 3BC/IRQ7, and Disabled.
Parallel Port Mode
Select an operating mode for the onboard parallel (printer) port. There are four options: SPP
(Standard Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities Port) and
ECP+EPP.
