Gator Mini-ITX – Installation Guide
LBA Mode LBA (Logical Block Addressing) is a method of addressing data on a disk drive. Your AMIBIOS is
already equipped with 48-bit LBA mode addressing.
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.
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
•
MO
LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive. The Optimal and Fail-Safe default
setting is
Auto.
Note: Your AMIBIOS is equipped with 48-bit LBA mode addressing for drive capacities over 137 GB.
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.
Block (Multi-Sector Transfer)
This option sets the block mode multi sector transfers option. The Optimal and Fail-Safe default setting is Auto.
Disabled Set this value to prevent the BIOS from using Multi-Sector Transfer on the specified channel. The data to and
from the device will occur one sector at a time.
Auto Set this value to allow the BIOS to auto detect device support for Multi-Sector Transfers on the specified channel.
If supported, Set this value to allow the BIOS to auto detect the number of sectors per block for transfer from the hard
disk drive to the memory. The data transfer to and from the device will occur multiple sectors at a time. This is the
default setting.
PIO Mode
IDE PIO (Programmable I/O) mode programs timing cycles between the IDE drive and the programmable IDE
controller. As the PIO mode increases, the cycle time decreases. The Optimal and Fail-Safe default setting is
Auto .
Auto Set this value to allow the BIOS to auto detect the PIO mode. Use this value if the IDE disk drive support cannot
be determined. This is the default setting.
0 Set this value to allow the BIOS to use PIO mode 0. It has a data transfer rate of 3.3 MBs.
1 Set this value to allow the BIOS to use PIO mode 1. It has a data transfer rate of 5.2 MBs.
2 Set this value to allow the BIOS to use PIO mode 2. It has a data transfer rate of 8.3 MBs.
3 Set this value to allow the BIOS to use PIO mode 3. It has a data transfer rate of 11.1 MBs.
4 Set this value to allow the BIOS to use PIO mode 4. It has a data transfer rate of 16.6 MBs. This setting generally
works with all hard disk drives manufactured after 1999. For other disk drive, such as IDE CD-ROM drives, check the
specifications of the drive.
DMA Mode
This setting allows you to adjust the DMA mode options. The Optimal and Fail-Safe default setting is Auto .
