Aggressive Link Power Management
In AHCI mode, makes it possible to allow Aggressive Link Power Management
(ALPM) to save energy.
1. Disabled – ALPM is disabled
2. Enabled – ALPM is enabled
Serial ATA Controller 0
In IDE mode, defines the mode in which the SATA controller 0 will be operated.
1. Disabled – the SATA controller 0 is disabled
2. Enhanced - The resources allocated to the SATA controller 0 are not
restricted to the legacy resources. Depending on the operating system, the
performance may be higher than in compatible mode.
3. Compatible - Only pre-defined legacy resources (I/O ports, IRQ) will be
allocated to the SATA controller 0. This mode is particularly suitable for older
operating systems when the enhanced or AHCI mode is not supported.
Serial ATA Controller 1
In IDE mode, defines the mode in which the SATA controller 1 will be operated.
1. Disabled – the SATA controller 1 is disabled
2. Enhanced - The resources allocated to the SATA controller 1 are not
restricted to the legacy resources. Depending on the operating system, the
performance may be higher than in compatible mode.
Staggered Spin-Up
Reduces the electrical load during boot up of systems with multiple SATA devices.
The SATA devices run one after the other at the request of the HOST controller.
1. Disabled – staggered spin-up is disabled
2. Enabled – Staggered spin-up is enabled
External SATA Port
Specifies whether the port will be operated internally as SATA or externally as
eSATA.
1. Disabled – the port will be used internally as SATA
2. Enabled – the port will be used as external SATA (eSATA)
Hot Plug
Specifies whether hot plug support of the port is enabled.
1. Disabled – the hot plug support of the port is disabled
2. Enabled – the hot plug support of the port is enabled
