What is the GigaRAID (IT8212) ATA RAID Controller
This GigaRAID (IT8212) ATA RAID Controller is an excellent product resulting from
Soc concept. It includes one RAID Chip combining CPU, firmware, advanced PCI
controller and IDE controller. Its architecture can provide users a RAID system with
low CPU utilization. When a PC is in high CPU operation or PCI traffic, users won’t
have any penalties for installing RAID system. This is because this system embeds a
local CPU to deal with the RAID function and it’s unnecessary to share CPU’s
performance. It is entirely different from the traditional software RAID system.
Similarly, it also provides users more system stability. It provides users high speed
and integration and low price PC RAID system. Additionally, it also provides PCI
33MHz interface and is compatible with PCI spec. v2.2. It can be easily installed into
the PC system nowadays. Besides, we provide each OS a corresponding driver so
that users don’t have to worry that your systems and the IDE RAID system have any
compatibility issue.
This GigaRAID (IT8212) ATA RAID Controller can support IDE drivers ranging from
the lowest speed of PIO mode drive to the highest speed of ATA/133 drive. Thus,
users can use this characteristic to combine RAID system without any limitations.
Users can use ATA/133 drive and RAID function to achieve the best performance and
get the merit of system’s stability.
The GigaRAID (IT8212) ATA RAID Controller can support the RAID0 (striping),
RAID1 (mirroring), RAID0+1 (striping and mirroring) or JBOD (spanning) mode.
When a system is programmed to the RAID0 mode, it can read or write two drivers at
the same time to enhance the performance. When a system is programmed to the
RAID1 mode, two drivers have the same data and it will prevent data from being
damaged. Once data is damaged, the system will start the rebuild function
automatically and save data back to another new drive. Similarly, this system can use

this data-copying characteristic to let two drivers transmit at the same time and
balance the performance to raise throughput. The RAID0+1 mode uses four drivers
to get the merits of RAID0 and RAID1. As for the JBOD mode, it combines more than
two drives into a drive with a large capacity. This mode does not have the RAID
function and its merit.
Quick Start
This section leads you to quickly establish your RAID system with default settings.
The default settings can meet most people’s requirements. If you need more
advanced optimal, please refer to Setup Utility on page 15 to achieve your goal.
Warning: In order to prevent any data loss resulting from
inappropriate operation, please backup data before you start to
install your system.

The hard drives which are required for the installation
The hard drives, which are connected on the GigaRAID (IT8212) ATA RAID Controller,
can support Ultra ATA/ 133, Ultra ATA/ 100, Ultra ATA/ 66, Ultra ATA/33, EIDE or Fast
ATA-2 drives. Nevertheless, for the best performance, it is suggested that you had
better use the hard drives of the same type and capacity to establish your own RAID
system. After getting ready for the hard drives, you can follow the procedures below
to install the system.
1. Exactly set up every hard drive’s master and slave setting to assure that the
hard drives can surely action and unnecessarily incorrect action of data access
won’t occur.
2. Exactly insert the hard drive’s cables into the connectors on the hard drive and
check if it’s really firmly inserted.
3. Insert every power cable connector into the corresponding hard drive and
check if it’s firmly inserted in a correct direction.
Warning: Because this system can support the hard drives of
Ultra ATA/133, it is suggested that you can use the 80-wire,
40-pin cable to connect the GigaRAID (IT8212) ATA RAID
Controller and hard drives in order to assure the system’s ability
and efficiency. If the cable is damaged after a period of time, it is also
suggested to buy the cable of the same specification.

Create Your Disk Array
You can create your own array using the onboard BIOS utility of the
GigaRAID (IT8212) ATA RAID Controller with the attached hard drives. Please follow
the steps below to setup your disk array.
Warning: Please backup data in your hard drives to prevent data
damage resulting from the unfamiliarity with the operation.
1. Boot your system
Please attach your hard drives to the GigaRAID (IT8212) ATA RAID Controller,
boot your system and then you will see the following message shown by the
GigaRAID (IT8212) ATA RAID Controller onboard BIOS on the screen.
