EXPANSION BOARD(S)

The desktop system has four expansion slots, the minitower system has five expansion
slots:
n
three ISA slots in the desktop system, four ISA slots in the minitower system
n
one shared PCI/ISA slot.
ISA expansion slots support industry-standard 8-bit or 16-bit expansion boards. The
PCI/ISA slot also supports PCI expansion boards.
PCI expansion boards run at the system's processor speed. The PCI bus handles 32 bits of
data at a time, being wider as well as faster than the standard ISA bus. PCI boards can send
and receive data much faster which boosts system performance.
