Abstract
A system and method for upgrading a computer is disclosed. Certain essential chips present in the original computer system are functionally, but not physically, removed from the computer system. The functions which would otherwise be performed by the original chips are instead performed by higher-performance chips on a plug-in module which is plugged into the computer system. The functional removal of the certain chips from the original computer system is achieved through simple insertion of the plug-in module. No replacement or substitution of original chips or boards is necessary.
