Advanced Bios Setup, Continued; Type; Lba/Large Mode - Kontron CP6500-V User Manual

Advanced BIOS Setup,
Parameter Description
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:
•

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.
