Intel® ICH5R Serial ATA RAID Introduction
The south bridge ICH5R provides a hybrid solution that combines two
independent SATA ports for support of up to two Serial ATA (Serial
ATA RAID) drives.
Serial ATA (SATA) is the latest generation of the ATA interface. SATA
hard drives deliver transfer speeds of up to 150MB/sec.
•
Supports 150 MB/s transfers with CRC error checking
•
Data handling optimization including tagged command queuing,
elevator seek and packet chain command
Parallel ATA and Serial ATA device configurations
ATA Operate Mode
There are two modes to choose from: Legacy mode and Native mode.
1.
Legacy Mode
•
System BIOS assigns 14 and 15 IRQs for HDD use
•
Older OSs that do not support Native Mode (DOS, Win2K, Win98/
ME...) should set S-ATA and P-ATA to Legacy Mode
•
Maximum 4 ATA devices to connect under Combined mode or
Non-Combined mode
a
Non-Combined Mode: S-ATA devices only - Maximum of 2
devices
b
Non-Combined Mode: P-ATA devices only - Maximum of 4
devices
c
Combined Mode: S-ATA devices and P-ATA devices - 2 devices
each (Maximum of 4 devices)
2.
Native Mode
•
System BIOS will search all available IRQs for HDD use
•
New OSs that support Native Mode (WinXP, Windows.NET Server)
can set S-ATA and P-ATA to Native Mode
•
Comprehend both Legacy and/or Native Modes
•
Maximum of 6 devices can be connected (4 P-ATA and 2 S-ATA)
