BIOS Setup
IR Transmission Delay:
This option enables or disables the IR transmission delay. When set to [Enabled], the
transmission will be slower. This is recommended when transmission problem arise.
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.
Use IR Pins
Leave this item to its default [IR-Rx2Tx2] setting to use the IR header on your
motherboard to connect your IR kit. Select [RxD2] or [TxD2] only if your
motherboard supports a COM port IR kit connection.
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.
[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.
[EPP+ECP]: Using parallel port as EPP & ECP mode.
