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: T one ISA slot T three PCI slots T one shared ISA/PCI slot T one AGP slot. The following figure shows expansion slot locations. 3-6 Option Installation Figure 3-3 Locating Expansion Slots Expansion Board Installation Install expansion boards in the system as follows. 1. Follow any preinstallation instructions that come with the expansion board (such as setting switches or jumpers on the board). 3. Remove the screw securing an expansion slot cover and remove the cover. Figure 3-4 Removing the Slot Cover Option Installation 3-7 Save the screw for installing the expansion board. Be sure to save the slot cover for future use. CAUTION: A slot cover can damage the system board or any option board if it falls into the system. Take care to keep the slot cover from falling when removing the screw. [. . . ] The Department does not guarantee the equipment will operate to the user's satisfaction.
