ECP DMA Select (3)
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.
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 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 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, 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
auto-detection to ensure optimal performance.
