C-1

Appendix C

Intel HostRAID

After the hardware has been installed, you must ﬁ rst conﬁ gure Intel's ICH7R SATA

RAID before you install Windows and software drivers.

Important Notes to the User

Note: If you do not wish to conﬁ gure onboard SATA RAID functions, please go

directly to Section C-2 for Operating System & Other Software Installation.

This chapter describes RAID conﬁ guration instructions for the Intel ICH RAID

Controller designed for Windows OS. For Linux OS, please use the Adaptec

HostRAID Utility.

To use the Adaptec HostRAID, please enable Adaptec's RAID Controller in BIOS

and refer to the Adaptec HostRAID Utility and documentation included in the CD

that came with your motherboard for instructions.

C-1 Introduction to Serial ATA and Parallel ATA

To conﬁ gure the SATA RAID functions, you must ﬁ rst use the Intel ICH7R SATA

RAID Utility program to conﬁ gure the RAID level that you desire before installing

Windows XP/2000/2003 and software drivers. (The necessary drivers are all included

on the CD that came with your motherboard.) Note that the current version of the

ICH7R SATA RAID Utility can only support Windows XP/2000/2003.

Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that uses a single cable with a

minimum of four wires to create a point-to-point connection between devices. It is

a serial link, which supports transfer rates up to 3Gbps. Because the serial cables

used in SATA are thinner than the traditional cables used in Parallel ATA (PATA),

SATA systems have better airﬂ ow and can be installed in smaller chassis than

Parallel ATA. In addition, the cables used in PATA are limited to a length of 40cm,

while Serial ATA cables can be up to one meter in length. Overall, SATA provides

better functionality than PATA.

Introduction to Intel ICH7R Serial RAID

Located in the South Bridge of the Intel 3010 chipset, the I/O Controller Hub (ICH7R)

provides the I/O subsystem with access to the rest of the system. It supports a 2-

channel UltraATA/100 Bus Master IDE controller (PATA) and four Serial ATA (SATA)

ports. The ICH7R supports the following PATA and SATA device conﬁ gurations:

Legacy mode and Native mode.
