Abstract: A portable computer having a main body provided with a modem signal processing part and a wireless network communication module includes an external antenna transmitting a radio signal for a wireless data communication with the wireless network communication module, an external modem connector transmitting a modem signal for a modem communication with the modern signal processing part, and a common connector coupling the external modem-connector to the modem signal processing part and the external antenna to the wireless network communication module. With this configuration, the portable computer has a good efficiency of a radio signal transmission and provides an installation space for another hardware components.

Abstract: A computer system comprises: a non-volatile memory for storing therein a BIOS table relating to basic operation of the computer system; an auxiliary memory for storing an operating system of the computer system; an information memory provided in the auxiliary memory for storing therein information on the operating system; and a BIOS controller for automatically setting up the BIOS table of the non-volatile memory based on the OS information stored in the information memory when a BIOS POST routine of the computer system is executed. With this configuration, although an auxiliary memory device storing the OS of the computer system according to the present invention is replaced, the OS information can be automatically set up in the BIOS table, thereby providing a convenience to the user. In addition, according to the present invention, a computer system needs no rebooting thereof due to OS change in the BIOS table.

Abstract: A computer system equipped with a LAN signal processing part and a modem signal processing part comprises: a common connector to which an external LAN connector to be connected to the LAN signal processing part and an external modem connector to be connected to the modem signal processing part are selectively connected; a connector detector provided at the common connector for detecting which of the external LAN connector and the external modem connector is connected to the common connector; and a control part for controlling a predetermined signal to be transmitted to one of the LAN signal processing part and the modem signal processing part in correspondence to the external connector detected by the connector detector. With this configuration, the cost of production decreases, and space for an installation of hardware components is more plentiful.
