Abstract
A computer system having a genetic code that cannot be directly accessed by processors or other master devices. In the computer system of the invention, a genetic code display procedure (GDP) and a genetic code setup procedure (GSP) are required to maintain the genetic code. In the GDP, the genetic code is transmitted to a monitor under the control of the processor, but cannot be directly accessed by the processor. In the GSP, a new key-in genetic code is transmitted to a memory device storing the genetic code, but cannot be directly accessed by the processor. Therefore, the genetic code of the computer system is secure and maintainable.
