[. . . ] Modify the boot order of bootable devices such as hard drives, diskette drives, CD-ROM drives, DVD-ROM drives, or LS-120 drives. Configure the boot priority of IDE and SCSI hard drives controllers. Configure Quiet Drive options (for drives that support this feature). Enable Quick Boot, which is faster than Full Boot but does not run all of the diagnostic tests run during a Full Boot. [. . . ] Options are 3. 5" 1. 44 MB, 3. 5" 720 KB, 5. 25" 1. 2 MB, 5. 25" 360 KB, and Not Installed. Drive Emulation (LS-120 and ATAPI Zip drives only) Allows you to select a drive emulation type for a storage device. (For example, a Zip drive can be made bootable by selecting disk emulation. ) Drive Type IDE LS-120 ATAPI Zip drive Emulation Options None (treated as diskette drive) Disk (treated as hard drive) None (treated as Other) Diskette (treated as diskette drive) Disk (treated as hard drive) Transfer Mode (IDE 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. Support for Computer Setup options may vary depending on your specific hardware configuration. Continued Computer Setup Guide 5 Computer Setup Continued Heading Storage (continued) Option Device Configuration (continued) Description 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. 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. · Note: 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 6 Computer Setup Computer Setup Continued Heading Storage (continued) Option Options Description Removable Media Boot Enables/disables ability to boot the system from removable media. Note: After saving changes to Removable Media Boot, the computer will restart. Turn the computer off, then on, manually. Removable Media Write Enables/disables ability to write data to removable media. Note: This feature applies only to legacy diskette, IDE LS-120 Superdisk, and IDE PD-CD drives. Primary IDE Controller Allows you to enable or disable the primary IDE controller. Secondary IDE Controller Allows you to enable or disable the secondary IDE controller. Diskette MBR Validation Allows you to enable or disable strict validation of the diskette Master Boot Record (MBR). [. . . ] This feature reruns the video option ROM on a boot from the S3 state. · · Device Options Allows you to set: · · · · · · · · Support for Computer Setup options may vary depending on your specific hardware configuration. * These options should be used by advanced users only.
