You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. 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. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. 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 1.5 for the supported version of ATAPI). PCI IDE connectors with independent I/O channel support. If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two Any interrupts set to Available in Setup are considered to be available for use by the add-in card.įor information about the versions of PCI and Plug and Play supported by the BIOS, see Section 1.5. 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. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. PCI devices may be onboard or add-in cards. The BIOS can automatically configure PCI devices. 3.3 Resource Configuration 3.3.1 PCI Autoconfiguration Internally, the device is grouped into eight 64-KB blocks that are individually erasable, lockable, and unlockable.
