Description (Continued)
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.
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 Bit-Shift, LBA
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 multi-sector 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.
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.
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.
