Intel ICH5R Serial ATA RAID Introduction

Appendix B: Intel ICH5R Serial ATA RAID Introduction
The southbridge 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 blistering transfer speeds of up to 150MB/sec. Serial ATA uses long, thin cables, making it easier to connect your drive and improving the airflow inside your PC. 1. Supports 150 MB/s transfers with CRC error checking 2. Data handling optimizations including tagged command queuing, elevator seek and packet chain command

Introduction
Following are the Parallel ATA (P-ATA) and Serial ATA (S-ATA) device configurations supported by Intel ICH5R.

ATA Operate Mode There are two modes to select: Legacy mode and Native mode. Legacy Mode: --- In this mode, system BIOS just assign the traditional 14 and 15 IRQs to use for HDD. --- Older OSs that do not support switch to Native Mode (DOS, Win2K, Win98/ME...) should set SATA and PATA to Legacy Mode. --- Maximum 4 ATA devices to connect. --- Combine mode and Non-Combine mode. Non-Combined Mode: P-ATA devices only . Maximum of 4 devices. Non-Combined Mode: S-ATA devices only. Maximum of 2 devices. Combined Mode: S-ATA devices P-ATA devices Maximum of 2 devices each, thus total 4 devices at maximum. Native Mode: --- In this mode, system BIOS will search all available IRQs to use for HDD. --- New OS that support switch to Native Mode (WinXP, Windows .NET Server) can set SATA and PATA to Native Mode. --- Comprehend both Legacy and/or Native Modes. --- Maximum 6 ATA devices to connect (4 for P-ATA & 2 for S-ATA).
