Intel Desktop Board D848PMB Product Guide

Hi-Speed USB 2.0 Support

NOTE
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable.
Use a shielded cable that meets the requirements for a full-speed USB device.
The desktop board supports up to eight USB 2.0 ports via ICH5; four ports routed to the back
panel and four routed to the internal USB 2.0 headers. USB 2.0 ports are backward compatible
with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.
Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be
required to accommodate operating systems that do not support USB 2.0.
NOTE
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.

Enhanced IDE Interface

The ICH5's IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer.
The interface supports:
•
Up to four IDE devices (such as hard drives)
•
ATAPI-style devices (such as CD-ROM drives)
•
Older PIO Mode devices
•
Ultra DMA-33 and ATA-66/100 protocols
•
Laser Servo (LS-120) drives

Accelerated Graphics Port (AGP)

NOTE
Desktop Board D848PMB is only compatible with 0.8 V and 1.5 V AGP cards.
The AGP connector is keyed for 0.8 V and 1.5 V 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.
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.
AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.
The AGP 3.0 connector supports 8x, 4x, and 1x AGP cards.
