Chapter 4: BIOS Setup

NISE 103 User Manual

Type

Selects the type of IDE drive connected to the system.

LBA/Large Mode

Auto The LBA mode will automatically be enabled, that is, if the

LBA mode was not previously disabled.

Disabled Disables the LBA mode.

Block (Multi-Sector Transfer)

Auto Data transfer to and from the device occurs multiple sectors at

a time.

Disabled Data transfer to and from the device occurs one sector at a

time.

PIO Mode

Selects the data transfer mode. PIO means Programmed Input/Output.

Rather than have the BIOS issue a series of commands to effect a transfer

to or from the disk drive, PIO allows the BIOS to tell the controller what

it wants and then let the controller and the CPU perform the complete

task by themselves. Your system supports five modes, 0 (default) to 4,

which primarily differ in timing. When Auto is selected, the BIOS will se-

lect the best available mode after checking your drive.

Auto The BIOS will automatically set the system according to your

hard disk drive’s timing.

Mode 0-4 You can select a mode that matches your hard disk drive’s

timing. Caution: Do not use the wrong setting or you will

have drive errors.

DMA Mode

Selects the DMA mode.

Auto Automatically detects the DMA mode.

SWDMAn SingleWord DMAn.

MWDMAn MultiWord DMAn.

UDMAn Ultra DMAn.

S.M.A.R.T.

The system board supports SMART (Self-Monitoring, Analysis and Report-

ing Technology) hard drives. SMART is a reliability prediction technology

for ATA/IDE and SCSI drives. The drive will provide sufficient notice to

the system or user to backup data prior to the drive’s failure. SMART is

supported in ATA/33 or later hard drives. The options are Auto (default),

Enabled and Disabled.

32Bit Data Transfer

Enables or disables 32-bit data transfer.

IDE Detect Time Out (Sec)

Selects the time out value for detecting ATA/ATAPI devices.
