IR Transmission Delay
This field allows you to “Enable” or “Disable” the IR Transmission Delay.

UR2 Duplex Mode
This field appears in an infrared port mode. You have two options: half or full duplex
function. The full duplex mode allows bi-directional transmission at a single time
where as the half duplex mode only allows transmission in one direction at a time.
This setting depends on the nature of your IR peripheral device. Check the IR device’s
manual to determine the appropriate setting.

Use IR Pins
To determine the correct settings for the TxD and RxD signals of your IR peripheral
component, you need to consult the components manual.

they do you can try to change them.

Onboard Parallel Mode

port. Select Normal, Compatible, or SPP unless you are certain your hardware and
software both support one of the other available modes.

EPP Mode Select
This field allows you to choose the EPP version you want to use. We recommend that

graphics card will be activated first: either the PCI graphics card or the AGP graphics card.
If you have only installed one graphics card the BIOS will automatically detect it and you
do not need to set this field.
