Quick Hardware Setup Guide
Step 5 Install the IBM ATA 133 RAID Controller
Select a 3.3 V
or
5 V PCI slot and align the IBM ATA 133 RAID controller bus
connector to the slot, as shown below. Press down gently but firmly to make sure that
the card is properly seated in the slot. The bottom edge of the controller card should be
flush with the slot. Attach the controller to the computer chassis with the bracket screw.

Step 6 Set up the IDE devices
Before you install and connect the IDE drives, you must verify that each drive is set to
Cable Select (CS) addressing mode. To verify this, see the IDE drive documentation.
Step 7 Connect IDE Cables
Select the appropriate cables from the two types included with the RAID controller:
•
For any configuration where more than two drives will be connected to the
controller, select the standard length ATA-100/133 cables with two drive
connectors.
•
For 1U rack-mounted servers or in configurations where only two drives will be
connected to the controller, select the extended length ATA-100/133 cables with
single drive connector.
Use the selected ATA-100/133 cables to connect up to two IDE drives (one master and
one slave) to each 40-pin IDE connector on the IBM ATA 133 RAID controller. When
using the extended length cables, only one drive will be connected to each channel.
The two connectors are:
•
Primary IDE Channel connector (J3)
•
Secondary IDE Channel connector (J1)
Be sure to align Pin 1on the cable connectors with Pin 1 on IDE connectors J1 and J3,
as shown in the following figure.

Correct Order for Attaching the Drives
Each of the standard length ATA-100/133 cables has a connector at each end for a
master IDE device and another connector for a slave device. The following bullets
explain how to properly connect one, two, three, or four IDE drives:
•
One IDE drive:
Attach it to the master connector on the cable for the primary
IDE channel.
•
Two IDE drives:
Attach them to the master connectors on the two ATA-100/133
cables.
The following bullets apply only to the standard-length ATA 100/133 cable with two
drive connectors:
•
Three IDE drives:
Attach them to the master and slave connectors on the cable
for the primary IDE channel and the master connector on the cable for the
secondary connector.
•
Four IDE drives:
Attach them to the master and slave connectors on both ATA-
100/133 cables.
The following table displays the order in which you should connect the drives to the
RAID controller (as described above).

Step 8 Power Up
Replace the computer cover and reconnect the power cords. Turn on the power to the
computer. Observe the messages that display during the boot process until you see the
following message:
Press Ctrl-M to run MegaRAID IDE Setup Utility
Step 9 Run the BIOS Configuration Utility
When the ”Press Ctrl-M” message appears on the screen, press the <Ctrl> key and
<M> key immediately to run the BIOS Configuration Utility. See the
IBM ATA 133
RAID Controller User’s Guide
on the Driver and Documentation CD for information
about how to run and use this program.
Step 10 Install the Operating System Driver
The IBM ATA 133 RAID controller can operate under MS-DOS® or any DOS-
compatible operating system using the standard AT BIOS INT 13h Hard Disk Drive
interface. To operate with other operating systems, you must install software drivers.
IBM provides software drivers on the Driver and Documentation CD for the following
operating systems:
•
Microsoft Windows 2000 Server, Advanced Server, and Professional
•
Microsoft Windows XP Professional
•
Red Hat Linux 7.3
Refer to the
IBM ATA 133 RAID Controller User’s Guide
on the Driver and
Documentation CD for more information.
RAID Levels Supported
The IBM ATA 133 RAID controller supports disk arrays using the following RAID
levels:
RAID 0 (Disk striping)
Data is striped across all drives in the array, enabling very fast data throughput. No data
redundancy. All data is lost if any drive fails. (1-4 hard drives)
RAID 1 (Drive mirroring)
Data is written simultaneously to two drives, providing complete data redundancy in
case one drive fails. Array capacity is half of available drive space. (2 hard drives)
RAID 10 (RAID 0 and RAID 1 combined in a single array)
Uses mirrored pairs of drives to provide complete data redundancy. High data
throughput rates, greater capacity than RAID 1. (4 hard drives)
