Intel Desktop Board D865PCD Technical Product Specification

3.3 Resource Configuration

3.3.1PCI Autoconfiguration

The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card.

The versions of PCI and Plug and Play supported by the BIOS	Section 1.3, page 16

3.3.2PCI IDE Support

If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two

PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives (see Section 1.3 for the supported version of ATAPI). The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.

To use ATA-66/100 features the following items are required:

•An ATA-66/100 peripheral device

•An ATA-66/100 compatible cable

•ATA-66/100 operating system device drivers

✏NOTE

Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.
