Treiber für LSI SAS-RAID-Karte 9260, 9265, 9280, 9285 unter Windows

The LSI_SAS2.SYS driver meets the Microsoft specification for miniport drivers.
These drivers allow connection of SAS devices including disk drives,
CD/DVD-ROMs, and tape drives for PCI-Express based machines. To support a
different SAS device type, the Windows 7 architecture requires that a class
driver for that type of device be present (usually supplied by Microsoft, or
possibly by the peripheral manufacturer). No changes to the LSI drivers are
required. The driver supports only Windows 7 / Server 2008 R2 and all
subsequent Service Packs.

A Windows application passes SCSI commands directly to the SAS Protocol devices
by using the SCSI pass-through facility. This facility allows applications to
directly control and access devices by filling in a data structure and calling
into the port or class driver. Refer to the Microsoft Windows 7 documentation
for more details.

Follow the Windows driver installation procss in Device Manager, Properties, dirver update.
Install the driver from the appropriate folder for your Windows version.

Reboot will be required
