InstallingYour Hardware
Nexus GA fits into connectors called expansion slots, inside
your computer.
Your Mac OS computer has one or more slots, each designed to
accept Peripheral Component Interconnect (PCI) cards.
The following procedure details the installation of a card in a
typical Mac OS PCI-based tower computer. If your computer
does not match this configuration, please refer to the expansion
card installation instructions that came with your computer.
