Important information
PowerEdge systems with PERC S100 require S100 drivers
during operating system installation
Description The system reboots when you install the Windows Server OS by using the ROK media or the Unified Server
Configurator (USC), on the PowerEdge RAID Controller (PERC) S100.
Workaround To install OS, use the external USB-DVD drive.
NOTE: This issue is fixed in Windows Server 2008 R2 Service Pack 1. A message may be displayed
to install the driver, because the S100 driver is not available with Windows Server 2008 R2 Service
Pack 1 OS. Download and use the latest drivers from Dell.com/support/drivers. For more
information, see Downloading the drivers and firmware.
NOTE: Dell software RAID S100 and S300 are not supported on Windows Server 2016, Windows
Server 2012 and Windows Server 2012 R2.
