Use this item to select the type of device connected to the system. The options

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 support a 48-bit LBA mode. 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.
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 supports transfers of up to 64 KB per interrupt. Select
Disabled to allow data to be transferred from and to a device one sector at a
time. Select Auto to allow data transfer from and to a device multiple sectors at
a time if the device supports it. The options are Auto and Disabled.
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 AMI BIOS to automatically detect the PIO mode. Use this
value if the IDE disk drive support cannot be determined.
Select 0 to allow AMI BIOS to use PIO mode 0. It has a data transfer rate of
3.3 MB/s.
Select 1 to allow AMI BIOS to use PIO mode 1. It has a data transfer rate of
5.2 MB/s.
Select 2 to allow AMI BIOS to use PIO mode 2. It has a data transfer rate of
8.3 MB/s.
