The novel computer system (10) includes a host computer CPU (12), a first VGA graphics chip (14) associated with a first monitor (16), a second VGA graphics chip (18) associated with a second monitor (20) and a chip manager application running on the host computer CPU (12). The chips (14 and 18) are interconnected to the CPU (12) via PCI buses (24 and 26). The chip manager application manages access to shared computer system resources by the chips (14 and 18) so as to allow for multiple VGA-chip initialization and avoid conflicts. The invention thereby allows for use of multiple VGA devices in a PCI computer system.
