2.6.1 On-Chip IDE Device

The system chipset contains IDE HDD Block mode, and a PCI IDE inter-
face with support for two IDE Primary (Master & Slave) PIO's and two
IDE Primary (Master & Slave) UDMA's, and two IDE Secondary (Master
& Slave) PIO's and two IDE Secondary (Master & Slave) UDMA's.
Select Enabled to activate the primary and/or secondary IDE interface.
Select Disabled to deactivate this interface if you install a primary and/or
secondary add-in IDE interface.

2.6.2 USB Controller

Select Enabled if your system contains a Universal Serial Bus controller
and you have USB peripherals.

2.6.3 USB Keyboard Support

Select Enabled if your USB controller is enabled and it needs USB key-
board support in legacy (old) OS operating systems such as DOS.

2.6.4 AC'97 Audio

Selecting Auto will enable the AC'97 audio if it is detected onboard.

2.6.5 Onboard LAN Boot ROM

Decides whether to invoke the boot ROM of the onboard LAN chip. The
available choices are LAN1, LAN2, and Disabled.

2.6.6 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 in this field.

2.6.7 Onboard Serial Ports 1 and 2

Select an address and corresponding interrupt for the first and second
serial ports. The choices: Disabled, 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4,
2E8/IRQ3.

2.6.8 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.
