Computer Setup-Storage NOTE: Support for specific Computer Setup options may vary depending on the hardware configuration. Table 3 Computer Setup-Storage Option Description Device Configuration Lists all installed BIOS-controlled storage devices. When a device is selected, detailed information and options are displayed. The following options may be presented. Hard Disk ● None (prevents BIOS data accesses and disables it as a boot device). ● Hard Disk (treated as hard disk). 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. 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 Off. 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) NOTE: This feature appears only when User translation mode is selected. Storage Options 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. Default Values IDE/SATA Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and Translation Mode for ATA devices. Removable Media Boot Enables/disables ability to boot the system from removable media. BIOS DMA Data Transfers Allows you to control how BIOS disk I/O requests are serviced. When Enable is selected, the BIOS will service ATA disk read and write requests with DMA data transfers. When Disable is selected, the BIOS will service ATA disk read and write requests with PIO data transfers. SATA Emulation 4 Computer Setup (F10) Utility ENWW

Option
Description
Device Configuration
Lists all installed BIOS-controlled storage devices.
When a device is selected, detailed information and options are displayed. The following options
may be presented.
Hard Disk
●
None (prevents BIOS data accesses and disables it as a boot device).
●
Hard Disk (treated as hard disk).
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.
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
Off.
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)
NOTE:
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.
Default Values IDE/SATA
Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and Translation
Mode for ATA devices.
Storage Options
Removable Media Boot
Enables/disables ability to boot the system from removable media.
BIOS DMA Data Transfers
Allows you to control how BIOS disk I/O requests are serviced. When Enable is selected, the BIOS
will service ATA disk read and write requests with DMA data transfers. When
Disable
is selected,
the BIOS will service ATA disk read and write requests with PIO data transfers.
