IV. BIOS (ChipsetFeatures) IV. BIOS SOFTWARE Onboard Parallel Port This field sets the address of the on-board 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 assignments. 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 allows bidirectional 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 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 on-board 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 on-board 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 25 for the Infrared Connector. IMPORTANT: For SMC37C665IR chipset, you must also physically set jumpers as well as change the 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. IV. BIOS (Chipset Features) 36 P/I-P55T2P4 User's Manual

Onboard Parallel Port
This field sets the address of the on-board parallel port connector.
You can
select either:
3BCH / IRQ 7,
378H / IRQ 7
(default)
, 278H / IRQ 5, Dis-
abled.
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
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
allows bidirectional 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
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
Par-
allel 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 on-board infrared feature and sets the
second serial UART to support the infrared module connector on the moth-
erboard.
If your system already has a second serial port connected to the
on-board 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 25
for the Infrared Connector.
IMPORTANT:
For SMC37C665IR chipset,
you must also physically set jumpers as well as change the 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.
