* CERC ATA 4ch
NOTE: In the above case, the option to install Red Hat Enterprise
Linux (version 4) will not be presented in the "Select Operating
Systems" page.
* Installation of Red Hat Enterprise Linux (all versions) operating
system is not supported on any system having the following
controllers:
* Promise RAID
* CERC SATA 2S in RAID mode
NOTE: In the above cases, option to install Red Hat Enterprise
Linux operating system will not be presented in the "Select
Operating Systems" page.
* Systems Build and Update Utility does not support Non RAID (Volume)
mode on S100/S300 SWRAID controllers.

KNOWN ISSUES FOR NOVELL SLES10/SLES11 OPERATING SYSTEMS
======================================================================
* The Novell SLES 10 / SLES 11 operating system installation may fail
on systems equipped with multiple RAID and/or SCSI controllers,
whether installed on the system board or in PCI slots. This failure
may occur when using Server Setup or performing a manual
installation. When two or more RAID or SCSI controllers are
present, install Novell SLES 10 / SLES 11 with only one configured
RAID or SCSI controller. Configure the other controllers after you
install the Novell SLES 10 / SLES 11 operating system.
* When certain cards, notably Qlogic or Emulex fiber channel cards,
are present in PowerEdge R805 and PowerEdge M905 systems, SLES 11
(and other linux kernels later than 2.6.27) may cause the system
to reboot when drivers for those cards are loaded.
The issue occurs because the linux kernel changes the memory address
assignments to certain add-on PCI devices such that they overlap the
second I/O APIC interrupt controller in the system.
To workaround the issue for the PowerEdge R805, you can:
- Set the Optical Drive Controller (under Integrated Devices) to
On in system setup.
This changes the system resource assignments such that this issue
does not occur.
If this workaround fails, you can:
- Add the kernel parameter acpi=noirq to the kernel command line
to prevent the linux kernel from using the I/O APIC interrupt
controllers.
To workaround the issue for the PowerEdge M905, you can:
