|
| Disk (treated as hard drive) |
|
|
|
|
|
| ||
| Storage | Device | Transfer Mode | (IDE devices only) | ||
| (continued) | Configuration | Specifies the active data transfer mode. Options (subject to | |||
|
| (continued) | device capabilities) are PIO 0, Max PIO, Enhanced DMA, Ultra | |||
|
|
| DMA 0, and Max UDMA. | |||
|
|
|
| |||
|
|
| 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 3.2). Options are | |||
|
|
| Assisted, User, and None. | |||
|
|
| Ä 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 | |||
|
|
| 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. | ||
|
| Options | Removable Media Boot |
| ||
|
|
| Enables/disables ability to boot the system from removable | |||
|
|
| media. | |||
|
|
| ✎ | After saving changes to Removable Media Boot, the | ||
|
|
|
| computer will restart. Manually, turn the computer off, then | ||
on.
