EXPANSION BOARDS
Your system supports industry standard architecture
(ISA) 8- and 16-bit expansion boards (Plug and Play and
non-Plug and Play). It also supports 32-bit Peripheral
Component Interconnect (PCI) expansion boards, which are
Plug and Play.
With Plug and Play expansion boards, you can install a
board in an expansion slot without changing the hardware
settings. There are no system resource conflicts to resolve.
Plug and Play automatically configures the board for the
system.
Locating Expansion Slots
The system has six expansion slots:
„
one AGP slot
„
two dedicated PCI slots
„
one shared PCI slot/RAIDport
„
one shared PCI/ISA slot
„
one ISA slot.
ISA expansion slots support industry-standard 8- or 16-bit
expansion boards.
PCI expansion boards run at half 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, boosting
system performance.
An AGP expansion board provides high-quality graphics on
a video board in support of the Advanced Graphics Port
(AGP) standard.
