Possible values of an option:
[Normal], [IrDA], [ASKIR]
[Normal], [IrDA], [ASKIR], [SCR]
The option description:
Some time ago for communication on small distances (we will tell, between a mobile phone and the computer) the infra-red port was often used. This device can be met in three variants of execution: first, the infra-red priemo-transmitter can be connected to one of computer COM-ports, secondly, for these purposes the USB-port can be used, thirdly, the priemo-transmitter can be connected to a special socket on the motherboard. And if first two variants demand only installation of drivers in the latter case, a pole to everything, it is necessary to execute certain options in BIOS Setup.
The described option just also allows to configure the second serial port (COM2) for work in a mode of infra-red port. Naturally, it is a question only of the infra-red priemo-transmitter connected to a special socket on the motherboard. The second COM-port is thus disconnected.
Value by default — [Normal] — assumes that the second serial port functions in a usual mode. The variant [IrDA] says that the corresponding equipment is connected to a socket on the motherboard, and the second COM-port is used as the infra-red.
In some versions BIOS value [IrDA] is supplemented with a variant [ASKIR]. In this case it is a question of concrete realisation of the infra-red interface. [IrDA] says that firm HP specifications (HPSIR — Hewlett-Packard Serial InfraRed), [ASKIR] are used — that the realisation offered Sharp (ASKIR means Amplitude Shift Keyed Infrared Port) is chosen. At a value choice it is necessary to mean that variant HP faster offered Sharp, besides it is supported by a considerable quantity of devices.
If the option meets together with
, That value [Normal] is absent — to use the second serial port as usual COM-port it is physically impossible, as it is not dissolved on the motherboard. If you do not use infra-red port, establish [Disabled] for
Sometimes among values is present and [SCR] — the input reader of smart cards. Choose it only when at you the similar device is really established and it actually is connected to a socket of infra-red port on the motherboard.
The overwhelming majority of input readers of smart cards use interface USB which is not demanding additional options in BIOS.
