EXPANSION BOARDS
Your computer’s system board features several expansion slots that can accommodate
accessory adapter boards, such as a sound board or TV board. Depending on the system
you purchased, some of these devices may be installed in your system.
The Direction Series supports ISA Plug and Play expansion boards. Plug and Play allows
the installation of 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.
Industry-standard 8-bit and 16-bit ISA, and 32-bit PCI expansion boards are supported in
the system unit. ISA expansion boards can be Plug and Play or non-Plug and Play boards.
PCI expansion boards run at one half the system host’s bus 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, thereby boosting system performance.
Expansion Slot Locations
Your system has six expansion slots:
„
one ISA slot
„
three PCI slots
„
one shared ISA/PCI slot
„
one AGP slot.
The following figure shows expansion slot locations.
