• a processor (CPU) configured to execute a master operating system core (MBS) and a first and a second operating system core (BS1, BS2) under the control of the master operating system core (MBS);
• a first mass memory (MS1) configured to store a software management database;
• and
• a second mass memory (MS2) configured to store system files and program files for the second operating system core (BS2),
• wherein the first operating system core (BS1) is configured to carry out software updates for the second operating system core (BS2) using the software management database.

A method for operating a computer system, the method comprising:

• storing a software management database in a first mass memory (MS1);
• storing system files and program files for a first operating system core (BS1) in the first mass memory (MS1) and/or a second mass memory (MS2);
• storing system files and program files for a second operating system core (BS2) in the second mass memory (MS2);
• executing a master operating system core (MBS);
• executing the first and second operating system cores (BS 1, BS2), each under the control of the master operating system core (MBS);
• and
• carrying out software updates for the second operating system core (BS2) by the first operating system core (BS1) using the software management database.
