ABSTRACT:
A method for managing use of a fixed memory space of a computer system is provided. The computer system interfaces with controllers for managing operation of devices that operate with the computer system. The method includes determining whether sufficient memory is allocated in the fixed memory space for initializing code for the controllers, and jumping to swappable portion of the fixed memory space. The method also includes executing code in the swappable portion of the fixed memory space. The method further includes loading additional code needed to initialize the controllers from an external memory chip to the fixed memory space where the additional code is executed to complete initialization of the controllers of the computer system.
