Desktop Board Features 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. This desktop board supports up to six USB 2.0 ports via ICH4; four ports routed to the back panel and two routed to a USB front panel header. 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. Enhanced IDE Interface The ICH4'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 devices (such as CD-ROM drives) • Older PIO Mode devices • Ultra DMA-33 and ATA-66/100 protocols • Laser Servo (LS-120) drives Expansion Slots Desktop Board D845EPI has three PCI bus add-in card connectors. BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub. Related Links: For information about: • The BIOS Setup menus, go to Chapter 4 on page 51. • Instructions about updating the BIOS, go to Chapter 3 on page 47. PCI Auto Configuration If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card. 17
