Abstract:
A method of debugging in a computer system having a system memory, an integrated circuit socket that is normally used for mounting a BIOS memory, an input/output port, and a central processing unit connected to the system memory, the integrated circuit socket and the input/output port, the method comprising the steps of:mounting a debugging memory, different from a BIOS memory, which is programmed with a debugging routine which is different from BIOS on the integrated circuit socket, wherein said debugging memory replaces a BIOS memory during a debugging operation;connecting an external computer terminal to the input/output port; andactivating the computer system such that the central processing unit immediately executes the debugging routine which is different from BIOS when the computer system is activated and such that the central processing unit downloads and executes a plurality of software instruction codes from the external computer terminal, wherein the central processing unit provides a plurality of register values of the central processing unit to the external computer terminal when executing the plurality of software instruction codes from the external computer terminal to permit viewing of the plurality of register values on the external computer terminal.
