1. Introduction
The ALi M5283 is a highly integrated disk drive controller that is capable of managing Parallel-ATA
and Serial-ATA interface hard disk drives. The ALi controller supports PATA UDMA transfer mode
up to mode 6 and SATA 1.0 disk drives. The ALi M5283 also comes with cost-effective RAID
functionalities that can be used to increase data read/write speed and to provide protection to data
by distributing mirrored duplicates of data onto two disk drives (RAID1).
CAUTION!
You must properly configure the associated BIOS settings before the Ctlr+A
key combination can take effect. Please refer to Chapter 4 AMI BIOS
Setup, the discussions of the associated configurations for more details.
SATA disk drive support must be initiated under the following two BIOS
sub-menus.
1. Boot -> Onboard SATA ROM
2. Chipset -> Southbridge Chipset Configuration
You will not be able to access the ALi configuration utility unless you have
properly initiated the SATA disk drive support in the AMI BIOS configuration
utility.
CAUTION!
A configured RAID volume (which may consist of multiple hard drives)
appears to an operating system as a contingent storage space. Your
operating system will not be able to distinguish the physical disk drives
contained in a RAID configuration.
Precautions:
1. One key benefit a RAID configuration brings you is that a single hard drive can fail within a
RAID array without damaging your data. With RAID1 array, you can replace a failed drive
and restore your RAID configuration.
