inherent difficulties created by the legacy ATA master-slave architecture,
while maintaining compatibility with existing ATA firmware.
1.5.1 PCI Express Architecture
PCI Express is a local bus system designed to increase data transfers
without slowing down the central processing unit (CPU). You can install
MegaRAID PCI Express RAID controllers in PCI Express computer
systems with a standard bracket type. With these controllers in your
system, you can connect SAS devices and SATA II devices over the bus.
Note:
Some PCI-E slots support PCI-E graphics cards only; if a
RAID controller is installed on those PCI-E slots, it will not
function.
PCI Express goes beyond the PCI specification in that it is intended as
a unifying I/O architecture for various systems: desktops, workstations,
mobile, server, communications, and embedded devices.
1.5.2 Operating System Support

operating systems:
• Windows Vista, Server 2003, and Windows Server 2008
