5. A method for detecting the turning on of an expansion card connected to the expansion card connector of an electronic device and for setting a function mode, whereby the expansion card can be set in at least one of a first function mode and a second function mode, wherein in connection with the turning on of the expansion card, the following steps are taken in the expansion card:
-
a signal is generated and transmitted to the electronic device about the turning on of the expansion card, the expansion card is set in the first function mode, and a message is generated and transmitted to the electronic device about the setting of the first function mode, and wherein the turning-on signal and the function mode setting message are received in the electronic device and the following steps are taken in the electronic device; selecting the function mode to be set on the expansion card;
generating a function mode exchange message; and
transmitting the function mode exchange message to the expansion card;
conducting the exchange of the function mode to the selected function in the expansion card;
storing information about the function mode of the expansion card in the electronic device;
forming in the electronic device, in connection with the restart of the expansion card, a message comprising information in accordance with the stored information about the function mode of the expansion card; and
transmitting said message to the expansion card and setting the function mode of the expansion card to the mode indicated in said message. - View Dependent Claims (6, 7, 8, 9)
at the transmission stage, the messages complying with the first function mode are converted to messages complying with the second function mode, and at the receiving stage, the messages complying with the first function mode are converted from the messages complying with the second function mode.
