CA810 Motherboard Product Guide

USB Support

The motherboard has two USB ports. One of the USB ports can be routed to a front panel connector. You can connect two USB peripheral devices directly to the computer without an external hub. To attach more than two devices, connect an external hub to either of the built-in ports. The motherboard supports the standard universal host controller interface (UHCI) and takes advantage of standard software drivers written to be compatible with UHCI.

✏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 high-speed USB device.

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 can be upgraded by following the instructions in Section 3.

Intel® 82802AB Firmware Hub (FWH)

The BIOS is stored in the Intel 82802AB Firmware Hub. The firmware hub contains a nonvolatile memory core based on Intel® flash technology. In addition to storing the system BIOS, the firmware hub incorporates logic features such as a hardware random number generator (RNG). These logic features enable protection for storing and updating platform information relating to security and manageability.

PCI Auto Configuration

If you install a PCI add-in board 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 board. You do not need to run the BIOS Setup program after you install a PCI add-in board.

IDE Auto Configuration

If you install an IDE device (such as, a hard drive) in your computer, the IDE auto-configuration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing an IDE device.
