Drive Parameters
The “grayed-out” items in the left frame are the IDE disk drive parameters taken from the
firmware of the IDE disk drive selected. The drive parameters listed are as follows:
Parameter Description
Device
Type of device, such as Hard disk drive.
Vendor
Manufacturer of the device.
Size
The size of the device.
LBA Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In LBA mode,
the maximum drive capacity is 137 GB. For drive capacities over 137 GB, your AMIBIOS
must be equipped with 48-bit LBA mode addressing. If not, contact your motherboard
manufacturer or install an ATA/133 IDE controller card that supports 48-bit LBA mode.
Block Mode
Block mode boosts IDE drive performance by increasing the amount of data transferred. Only
512 bytes of data can be transferred per interrupt if block mode is not used. Block mode allows
transfers of up to 64 KB per interrupt.
PIO Mode
IDE PIO mode programs timing cycles between the IDE drive and the programmable IDE
controller. As the PIO mode increases, the cycle time decreases.
Async DMA
This indicates the highest Asynchronous DMA Mode that is supported.
Ultra DMA
This indicates the highest Synchronous DMA Mode that is supported.
S.M.A.R.T.
Self-Monitoring Analysis and Reporting Technology protocol used by IDE drives of some
manufacturers to predict drive failures.
Type
This option sets the type of device that the AMIBIOS attempts to boot from after the
Power-On Self-Test (POST) has completed. The Optimal and Fail-Safe default setting is
Auto.
Option Description
Not Installed
Set this value to prevent the BIOS from searching for an IDE disk drive on the specified
channel.
Auto
Set this value to allow the BIOS auto detect the IDE disk drive type attached to the specified
channel. This setting should be used if an IDE hard disk drive is attached to the specified
channel. This is the default setting.
CDROM
This option specifies that an IDE CD-ROM drive is attached to the specified IDE channel. The
BIOS will not attempt to search for other types of IDE disk drives on the specified channel.
ARMD
This option specifies an ATAPI Removable Media Device.
This includes, but is not limited to:
•
ZIP
•
LS-120
LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In LBA
mode, the maximum drive capacity is 137 GB. The Optimal and Fail-Safe default setting
is
Auto.
Note:
For drive capacities over 137 GB, your AMIBIOS must be equipped with 48-bit LBA
mode addressing. If not, contact your motherboard manufacturer or install an ATA/133
IDE controller card that supports 48-bit LBA mode.
Option Description
Disabled
Set this value to prevent the BIOS from using Large Block Addressing mode control on the
specified channel.
Auto
Set this value to allow the BIOS to auto detect the Large Block Addressing mode control on the
specified channel. This is the default setting.
