(Chipset Features)
Onboard FDC Swap A & B (No Swap)
This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Two options are available: No Swap and Swap AB. If you want to switch
drive letter assignments through the onboard chipset, set this field to Swap AB.

Onboard Serial Port 1 (3F8H/IRQ4)
Settings are 3F8H/IRQ4 (default), 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
abled for the onboard serial connector.

Onboard Serial Port 2 (2F8H/IRQ3)
Settings are 3F8H/IRQ4, 2F8H/IRQ3 (default), 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
abled for the onboard serial connector.

Onboard Parallel Port (378H/IRQ7)
This field sets the address of the onboard parallel port connector. You can select either
3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, or Disabled. If you install an I/O card
with a parallel port, ensure that there is no conflict in the address assignments. The PC
can support up to three parallel ports as long as there are no conflicts for each port.

Parallel Port Mode (ECP+EPP)
This field allows you to set the operation mode of the parallel port. The setting
Normal, allows normal-speed operation but in one direction only; EPP allows bidi-
rectional parallel port operation at maximum speed; ECP allows the parallel port to
operate in bidirectional mode and at a speed faster than the maximum data transfer
rate; ECP+EPP (default) allows normal speed operation in a two-way mode.

ECP DMA Select (3)
This selection is available only if you select either ECP or ECP+EPP as the
Parallel Port Mode. Select either DMA Channel 1, 3 (default), or Disable.

UART2 Use Infrared (Disabled)
When enabled, this field activates the onboard infrared feature and sets the second
serial UART to support the infrared module connector on the baseboard. If your
system already has a second serial port connected to the onboard COM2 connector,
it will no longer work if you enable the infrared feature. By default, this field is set
to Disabled, which leaves the second serial port UART to support the COM2 serial
port connector. See section III of the baseboard manual for the IrDA-compliant
infrared module connector.

Onboard PCI IDE Enable (Both)
You can select to enable the Primary IDE channel, Secondary IDE channel, Both
(default), or Disable both channels (for systems with only SCSI drives).

IDE 0 Master/Slave Mode / IDE 1 Master/Slave Mode (Auto)
Each channel (0 and 1) has both a master and a slave making four IDE devices
possible. Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4),
it is necessary for these to be independent. The default setting of Auto will allow
autodetection to ensure optimal performance.
