BIOS Dell recommends flashing the latest BIOS available to the system. This is posted on Dell's driver and downloads support web site (support.dell.com), under BIOS. Some of the BIOS settings are critical to operating system performance. These are as follows: • SATA configuration mode (Applicable to all Dell E-Family Notebook systems except Dell precision M6400 workstation): To access SATA configuration mode, select Settings→System Configuration→SATA Operation. - Disabled: SATA Controllers are hidden - ATA: Basic Disk Operation mode, does not require additional storage driver. NOTE: eSATA is not functional in this mode. - AHCI: SATA is configured for AHCI (Advanced Host Controller Interface) mode, which offers faster performance, eSATA support and increased battery life. This mode requires an additional storage driver provided by Dell if an operating system other than those previously specified is installed on the notebook. - IRRT (Default): SATA is configured to support IRRT (Intel's Rapid Recovery Technology), This mode supports AHCI mode features as well as disk mirroring (RAID-1). IRRT allows data backup and restoration. This mode requires an additional storage driver provided by Dell if an operating system other than those previously specified is installed on the notebook. NOTE: RAID support requires second hard disk drive. NOTE: This mode does not apply to E5400 and E5500 E-Family models. - RAID (Default): Applicable to Dell precision M6400 workstation only in lieu of IRRT mode. SATA is configured to support RAID. This mode supports AHCI mode features as well as disk mirroring (RAID-0 and RAID-1). RAID allows data backup and restoration. This mode requires an additional storage driver provided by Dell if an operating system other than those previously specified is installed on the notebook.
