Setup Utilities and Diagnostics Features Heading Option Description Storage (continued) Device Configuration (continued) Drive Emulation Allows you to select a drive emulation type for a certain storage device. (For example, a Zip drive can be made bootable by selecting diskette emulation.) Drive Type Emulation Options ATAPI Zip drive None (treated as Other) Diskette (treated as diskette drive) ATA Hard disk None (treated as Other) Hard disk (treated as hard drive) Legacy diskette No emulation options available CD-ROM drive No emulation options available ATAPI LS-120 None (treated as Other). Diskette (treated as diskette drive). Default Values IDE/SATA Multisector Transfers (ATA disks only) Specifies how many sectors are transferred per multi-sector PIO operation. Options (subject to device capabilities) are Disabled, 8, and 16. Transfer Mode (ATA devices only) Specifies the active data transfer mode. Options (subject to device capabilities) are PIO 0, Max PIO, Enhanced DMA, Ultra DMA 0, and Max UDMA. Translation Mode (ATA 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 Automatic, Bit-Shift, LBA Assisted, User, and None Ä 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 (ATA disks only) ✎ This feature appears only when User translation mode is selected. 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. ✎ Support for specific Computer Setup options may vary depending on the hardware configuration.
