Use these settings to set the parameters of the disc storage devices attached to the SATA ports.
Press <Enter> to activate the submenu screen for detailed item options. Set the correct
configurations accordingly. The submenu items are listed below.
Type
Select the device type connected to the system. The options are
Not Installed
,
Auto
,
CD/DVD
,
and
ARMD
.
LBA/Large Mode
Logical Block Addressing (LBA) 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, 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. You
can transfer only 512 bytes of data per interrupt if you do not use Block Mode. Block Mode
allows transfers of up to 64 KB per interrupt. If you select
Disabled
, data can transfer to and
from the device one sector at a time. If you select
Auto
, data can transfer to and from the device
multiple sectors at a time if the device supports this transfer method. The options are
Auto
and
Disabled
.
PIO Mode
The IDE Programmable I/O (PIO) mode programs timing cycles between the IDE drive and
programmable IDE controller. As the PIO mode increases, the cycle time decreases. The options
are
Auto
,
0
,
1
,
2
,
3
, and
4
.
If you select
Auto
, the AMI BIOS detects the PIO mode automatically. Use this value if you
cannot determine IDE disk drive support.
If you select
0
, the AMI BIOS uses PIO mode 0. The data transfer rate is 3.3 Mbytes/s.
If you select
1
, the AMI BIOS uses PIO mode 1. The data transfer rate is 5.2 Mbytes/s.
If you select
2
, the AMI BIOS uses PIO mode 2. The data transfer rate is 8.3 Mbytes/s.
If you select
3
, the AMI BIOS uses PIO mode 3. The data transfer rate is 11.1 Mbytes/s.
If you select
4
, the AMI BIOS uses PIO mode 4. The data transfer bandwidth is 32 bits. Select
Enabled
to enable 32-bit data transfer.
DMA Mode
If you select
Auto
, the BIOS detects IDE DMA mode automatically when you cannot determine
IDE disk drive support.
If you select
SWDMA0
, the BIOS uses single word DMA mode 0. The data transfer rate is
2.1 Mbytes/s.
