Abit IS7-M, IS7-G, IS7-E2V, IS7-E2G, IS7-V2 user manual Bios Setup UR2 Duplex Mode

BIOS Setup 3-17

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.
