3.3.5.2 LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In
the LBA mode, the maximum drive capacity is 137 GB. For drive capacities over
137 GB, your system must be equipped with a 48-bit LBA mode addressing. If not,
contact your manufacturer or install an ATA/133 IDE controller card that supports
48-bit LBA mode. The options are Disabled and
Auto .
3.3.5.3 Block (Multi-Sector Transfer)
Block Mode boosts the 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. Select Disabled
to allow data to be transferred from and to the device one sector at a time. Select
Auto to allow data transfer from and to the device to occur multiple sectors at a time
if the device supports it. The options are
Auto and Disabled.
3.3.5.4 PIO Mode
The 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 options are
Auto , 0, 1, 2, 3, and 4.
Select Auto to allow the AMI BIOS to automatically detect the PIO mode. Use this
value if the IDE disk drive support cannot be determined.
Select 0 to allow the AMI BIOS to use PIO mode 0. It has a data transfer rate of 3.3
MB/s.
Select 1 to allow the AMI BIOS to use PIO mode 1. It has a data transfer rate of 5.2
MB/s.
Select 2 to allow the AMI BIOS to use PIO mode 2. It has a data transfer rate of 8.3
MB/s.
Select 3 to allow the AMI BIOS to use PIO mode 3. It has a data transfer rate of 11.1
MB/s.
Select 4 to allow the AMI BIOS to use PIO mode 4. It has a data transfer bandwidth
of 32-Bits. Select Enabled to enable 32-Bit data transfer.
