IV. BIOS SOFTWARE
This field sets the address of the onboard parallel port connector. You can select
either: 3BCH I
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
allows normal-speed operation but in one direction only;
rectional parallel port operation at maximum speed;
operate in bidirectional mode and at a speed faster than the maximum data transfer
ECP+EPP
rate;
allows normal speed operation in a two-way mode.
ECP DMA Select (3)
This selection is available only if you select
Parallel Port Mode. Select either DMA Channel 1,3, or
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.
You can select to enable the
Disable
both channels (for systems with only SCSI drives).
IDE Ultra DMA Mode (Auto)
This sets the IDE UltraDMA to be active when using UltraDMA-capable IDE de-
vices. The BIOS will automatically adjust or disable this setting for slower IDE
devices so that Auto or high settings will not cause problems for older IDE devices.

if you do not want this feature for all devices.
IDE 0 Master/Slave PIO/DMA Mode, IDE 1 Master/Slave PIO/DMA 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. PI0 and DMA timings can be indepen-
dently set. The default setting of
