Intel Desktop Board D845PEBT2 Technical Product Specification 1.7.1 AGP AGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to handling large amounts of graphics data with the following features: • Pipelined memory read and write operations that hide memory access latency • Demultiplexing of address and data on the bus for nearly 100 percent efficiency ✏ NOTES • The AGP connector is keyed for 1.5 V Switching Voltage Level (SVL) AGP cards only; the connector is not mechanically compatible with legacy 3.3 V AGP cards. Do not attempt to install a legacy 3.3 V AGP card. • Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference with the memory retention mechanism. For information about The location of the AGP connector The signal names of the AGP connector Obtaining the Accelerated Graphics Port Interface Specification Refer to Figure 1, page 14 Table 38, page 64 Section 1.4, page 17 1.7.2 USB The Desktop Board D845PEBT2 supports up to six USB 2.0 ports, fully supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH4 provides the USB controller for all ports, as shown in Figure 4. The port arrangement is as follows: • Two ports are implemented with stacked back panel connectors, adjacent to the PS/2 connectors • Two ports are implemented with stacked back panel connectors, adjacent to the audio connectors • Two ports are routed to the front panel USB connector 82801DB I/O Controller Hub (ICH4) USB USB USB ports (2) USB ports (2) Back panel USB connectors adjacent to the PS/2 ports Back panel USB connectors adjacent to the audio connectors USB USB ports (2) Front panel USB connectors Figure 4.
