HP dx5150 RAID Installation
and Setup Guide
Introduction
RAID (Redundant Array of Independent Disks) technology
manages multiple disk drives to enhance I/O performance and to
provide redundancy in order to withstand the failure of any
individual member without loss of data.
SATARAID™ provides two RAID Set types: Striped Set (RAID
0) and Mirrored Set (RAID 1).
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by
writing the data simultaneously to two disks. This redundancy
provides protection from a single disk failure. If a read failure
occurs on one drive, the system then reads the data from the other
drive.
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping
technique. It does not provide fault tolerance. With modern
SATA and ATA bus mastering technology, multiple I/O
operations can be performed in parallel, enhancing performance.
Striping arrays use multiple disks to form a larger virtual disk.

Steps to Set Up RAID 1 in Mirror Mode
Enable RAID in the Computer BIOS:
1. Select ‘Integrated Peripherals’ in the Main Menu of F10
BIOS setup.
2. Select the ‘South OnChip PCI Device.’
3. Select ‘Onboard Chip SATA.’

4 www.hp.com Installation and Setup Guide
HP dx5150 RAID Installation and Setup Guide
4. When the ‘Onboard Chip SATA’ appears, select ‘RAID
Controller,’ press Enter to accept this selection and save the
setting to CMOS.
Note: To increase the amount of time needed to access the BIOS
RAID utility during post, you can change the default value of
zero seconds. The option to change the ’POST Delay’ is in the
F10 BIOS Setup in the ’Standard CMOS Features’ menu.
Create RAID Sets
1. During computer startup (POST), press the F4 function key to
display the BIOS RAID Configuration Utility.
2. Select ‘Create RAID set’ option.
3. Choose RAID 1 Mirrored Set

4. Select ‘Automatically Configure’ option.
5. Assign the source and target drive.
6. The message ‘Are You Sure?’ will display before completing
the configuration. Answer ‘N’ to abort the creation of the
new RAID set, or ‘Y’ to proceed with the RAID set creation.
7. Install the drivers for RAID in the Windows operating
system. Step 1a or 1b will need to be performed depending
on OS installation status.
Install RAID Drivers
Note: To install RAID Drivers while installing Microsoft
Windows XP operating system on the computer, go to
”B. Installing RAID Drivers during Microsoft Windows XP OS
Installation”.
A. Installing RAID Drivers on Microsoft Windows XP OS
1. Run the SETUP program for the ATI South Bridge Drivers
which are located in C:\Compaq\RAID\Setup on your HP
dx5150 computer or may be downloaded from the HP Web
site (www.hp.com or
http://h20180.www2.hp.com/apps/Lookup?h_lang=en&h_c
c=us&cc=us&h_page=hpcom&lang=en&h_client=S-A-R163-1
&h_pagetype=s-002&h_query=dx5150&submit.x=4&submit.y
=9). Please check the HP support Web site for possible
updates to these drivers in the future. Follow the instructions
on the screen once the SETUP program is launched.
2. Verify the drivers are installed after restarting the operating
system (the setup program in the previous step will prompt
for a system restart).
a. Right click on ‘my Computer’ icon, select ‘Properties,’
left click on ‘Hardware’ tab, and then on ‘Device
Manager’ button.

b. Double click on ‘SCSI and RAID Controllers.’ If there is
no yellow '!' or '?' in front of ‘ATI Serial ATA
Controller,’ the driver is installed correctly.
B. Installing RAID Drivers during Microsoft Windows XP
OS Installation
1. The RAID drivers are in the C:\Compaq\RAID\INF folder on
your HP dx5150 computer or may be downloaded from the
HP Web site (www.hp.com). Please check the HP support
Web site for possible updates to these drivers in the future.
The RAID drivers are included in the ATI Chipset softpaq.
