BIOS Setup
UR2 Duplex Mode:
This item selects the duplex mode required by the IR device connected to the IR port. Full-duplex mode
permits simultaneous two-direction transmission. Half-duplex mode permits transmission in one direction
only at a time. Refer to your IR KIT user's guide to find out which setting is correct.
Onboard Parallel Port:
This item specifies the I/O address used by the parallel port.
[Disabled]: This option prevents the parallel port from accessing any system resources. When the value
of this option is set to [Disabled], the printer port becomes unavailable.
[378/IRQ7]: This option allows the parallel port to use [378/IRQ7] as its I/O port address. The majority
of parallel ports on computer systems use IRQ7 and I/O Port 378H as the standard setting.
[278/IRQ5]: This option allows the parallel port to use [278/IRQ5] as its I/O port address.
[3BC/IRQ7]: This option allows the parallel port to use [3BC/IRQ7] as its I/O port address.
Parallel Port Mode:
This item specifies the parallel port mode.
[Normal]: Allows the standard parallel port mode to be used.
[SPP]: (Standard Parallel Port) Allows bi-directional parallel port operation at normal speed.
[EPP]: (Enhanced Parallel Port) Allows bi-directional parallel port operation at maximum speed.
[ECP]: (Extended Capabilities Port) Allows bi-directional parallel port operation at a speed faster than
the normal mode's data transfer rate.
[ECP+EPP]: Allows parallel port operation at ECP and EPP mode.
EPP Mode Select:
This item selects the EPP mode.
ECP Mode Use DMA:
This item selects the DMA channel of the parallel port.
