System does not boot after Configuration Changes

Hardware Changes
If the system does not boot after making changes to hardware or adding new
components, verify that the component installed is compatible with the server.
Software Changes
If you recently installed new software or new device drivers:
Try booting into Safe Mode and uninstall the new software or driver. If you can now
boot normally, there may be a compatibility issue between the new software or
driver and some component in your system. Contact the software manufacturer for
assistance
BIOS Changes
Changes to some advanced BIOS settings can cause boot issues. Changes to Advanced
BIOS settings should only be made by experienced users.
If the BIOS Setup Utility is accessible by pressing F2 during boot, reset the BIOS to factory
defaults by pressing F9. Save and exit the BIOS Setup.
If you cannot access the BIOS Setup Utility, clear the CMOS by performing the following
steps:
1. Power down the server. Do not unplug the power cord.
2. Open the server chassis.
