Setup Utilities and Diagnostics Features
Heading | Option | Description |
|
|
|
Storage | Device | Multisector Transfers (ATA disks only) |
(continued) | Configuration | Specifies how many sectors are transferred per |
| (continued) | operation. Options (subject to device capabilities) are Disabled, 8, |
|
| and 16. |
|
| 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 (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, |
|
| 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. |
|
| 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. |
|
|
|
|
| Legacy Diskette Write |
|
| Enables/disables ability to write data to legacy diskettes. |
|
| ✎ After saving changes to Removable Media Write, the computer |
|
| will restart. Turn the computer off, then on, manually. |
|
| BIOS DMA Data Transfers |
|
| Allows you to control how BIOS device I/O requests are serviced. |
|
| When “Enable” is selected, the BIOS will service ATA device read |
|
| and write requests with DMA data transfers. When “Disable” is |
|
| selected, the BIOS will service ATA device read and write requests |
|
| with PIO data transfers. |
✎Support for specific Computer Setup options may vary depending on the hardware configuration.
