Computer Setup Continued Heading Option Description Storage (continued) Device Configuration (continued) Translation Mode (IDE disks only) Lets you select the translation mode to be used for the device. This enables the BIOS to access disks partitioned and formatted on other systems and may be necessary for users of older versions of Unix (e.g., SCO Unix version 3.2). Options are Bit-Shift, LBA Assisted, User, and None. CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not be changed. If the selected translation mode is not compatible with the translation mode that was active when the disk was partitioned and formatted, the data on the disk will be inaccessible. Translation Parameters (IDE Disks only) Allows you to specify the parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate disk I/O requests (from the operating system or an application) into terms the hard drive can accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256. The number of sectors per track may not exceed 63. These fields are only visible and changeable when the drive translation mode is set to User. Multisector Transfers (IDE ATA devices only) Specifies how many sectors are transferred per multisector PIO operation. Options (subject to device capabilities) are Disabled, 8, and 16. Quiet Drive (available on select drives only) • Performance Allows the drive to operate at maximum performance. • Quiet Reduces noise from the drive during operation. When set to Quiet, the drive will not operate at maximum performance. If the drive does not support Quiet mode, the Quiet Drive option will not be displayed. Support for Computer Setup options may vary depending on your specific hardware configuration. Continued B-6 Computer Setup
