Patent ID: 7631112

Claim:
A computer system comprising: at least one connector comprising a plurality of pins configured to be removably connected to a first storage device and to a second storage device, wherein a first pin of the connector carries a signal that indicates when the connector is connected to the first storage device, and a second pin of the connector carries a signal that indicates when the connector is connected to the second storage device; a register that stores connection information that indicates whether the first storage device and/or the second storage device are connected to the connector; a basic input/output system (BIOS) ROM storing a BIOS code; a complementary metal oxide semiconductor (CMOS) RAM storing user-definable device information that indicates whether the first storage device and/or the second storage device are connected to the connector; and a processor configured to carry out a power-on self-test (POST) according to the BIOS code in the BIOS ROM, and to store the connection information, indicating whether the first storage device and/or the second storage device are connected to the connector, from the register into the CMOS RAM when the user-definable connection information for the first storage device and/or the second storage device is different from the connection information in the register.
