2.5.2 SATA Configuration While entering Setup, the BIOS automatically detects the presence of SATA devices. The SATA Port items show Not Present if no SATA device is installed to the corresponding SATA port. OnChip SATA Channel [Enabled] Enables or disables onboard channel SATA port. Configuration options: [Disabled] [Enabled] OnChip SATA Type [IDE] Allows you to set the SATA configuration. [IDE] Set to [IDE] when you want to use the Serial ATA hard disk drives as Parallel ATA physical storage devices. [RAID] Set to [RAID] when you want to create a RAID configuration from the SATA hard disk drives. [AHCI] Set to [AHCI] when you want the SATA hard disk drives to use the AHCI (Advanced Host Controller Interface). The AHCI allows the onboard storage driver to enable advanced Serial ATA features that increases storage performance on random workloads by allowing the drive to internally optimize the order of commands. SATA Port 5 - Port 6 [RAID] / [AHCI] This item only appears when the previous item is set to [RAID] or [AHCI]. If Port 5-6 are configured as [AHCI] or [RAID], the ports can only be used under OS with driver installed. Set to [IDE] instead of [AHCI] or [RAID] to access devices on Port 5-6 before entering OS. Configuration options: [RAID] / [AHCI], [IDE] S.M.A.R.T. Status Check [Enabled] S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a monitor system. When read/write of your hard disk errors occur, this feature allows the hard disk to report warning messages during the POST. Configuration options: [Enabled] [Disabled] 2.5.3 USB Configuration The items in this menu allow you to change the USB-related features. The USB Devices item shows the auto-detected values. If no USB device is detected, the item shows None. Legacy USB Support [Enabled] [Enabled] Enables the support for USB devices on legacy operating systems (OS). [Disabled] The USB devices can be used only for the BIOS setup program. [Auto] Allows the system to detect the presence of USB devices at startup. If detected, the USB controller legacy mode is enabled. If no USB device is detected, the legacy USB support is disabled. 2-18 ASUS F1A55
