Abstract

A method for operating an expansion card of a computer is proposed, said computer having at least one slot for accommodating the expansion card, wherein there is stored in a memory area of the expansion card a first and a second configuration data record, one of which is assigned to a first and the other to a second signaling voltage, and wherein the configuration data records transmitted to a FPGA chip of the expansion card indicate to the FPGA chip whether a protection circuit is to be activated or deactivated. Suitable measures enable functional units of a PCI expansion card suitable for both a 3.3 V and a 5 V signaling voltage to be integrated in an FPGA together with a PCI controller, the expansion card being supplied or suppliable with an external voltage independently of a signaling voltage of a computer or basic system.
