Onboard LAN Boot ROM

Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the sys-
tem board and you wish to use it. If you install an add-in FDC or the system has no
floppy drive, select Disabled in this field.
Onboard Serial Ports (1, 2)
Select an address and corresponding interrupt for the first and second serial ports.
The choices: Auto, 3F8/IRQ4, 3E8/IRQ4, 2F8/IRQ3, 2E8/IRQ3, Disabled.
UART Mode Select
This item allows you to select UART mode.
The choices: 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 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.
