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 four USB 2.0 ports via ICH4; two 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.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling Hi-Speed USB in 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 ICH4's IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip
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 D845GLVA 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.
The BIOS can be updated by following the instructions in Chapter 3 on page 31.
