Onboard Parallel Port

This field sets the address of the onboard parallel port connector. You can select

either: 3BCH / IRQ 7, 378H / IRQ 7 (default), 278H / IRQ 5, Disabled. If you install

an I/O card with a parallel port, ensure that there is no conflict in the address assign-

ments. The PC can support up to three parallel ports as long as there are no conflicts

for each port.

Parallel Port Mode

This field allows you to set the operation mode of the parallel port. The default

setting Normal, allows normal-speed operation but in one direction only; EPP al-

lows bidirectional parallel port operation at maximum speed; ECP allows the paral-

lel port to operate in bidirectional mode and at a speed faster than the maximum data

transfer rate; ECP+EPP allows normal speed operation in a two-way mode.

ECP DMA Select

This selection is available only if you select ECP or ECP+EPP in the Parallel Port

Mode. Select either DMA Channel 1, 3, or Disable. The setup default is DMA

Channel 3.

UART2 Use Infrared

When enabled, this field activates the onboard infrared feature and sets the second

serial UART to support the infrared module connector on the motherboard. 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 page 26 for the Infrared Connector.

IMPORTANT: For SMC37C665IR chipset, you must also physically set

jumpers on page 7 as well as change the chipset setting.

Onboard PCI IDE Enable

You can select to enable the primary IDE channel, secondary IDE channel, both

(default), or disable both channels (for systems with only SCSI hard drives).

IDE 0 Master/Slave Mode, IDE 1 Master/Slave Mode

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

auto-detection to ensure the optimal performance.
