This item is used to select the type of device connected to the system. The op-
tions are Not Installed, Auto, CD/DVD and ARMD.
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 able to support 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.
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 of up to 64 KB of data be transferred
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 to be transferred between
devices with 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 the AMI BIOS to automatically detect the PIO mode. Use
this value if the IDE disk drive support cannot be determined.
Select 0 ~ 4 to allow the AMI BIOS to use PIO mode 0 ~ 4. It has a data transfer
rate of 3.3 MB/s ~ 16.6 MB/s. See the table below.
