If a BIOS-update program CD is provided with a new system board, flash the BIOS from the CD. If you do not have a BIOS-update program CD, flash the BIOS
from the hard drive.
NOTICE: If you are replacing the system board, make sure the correct SATA mode is selected in the system setup program. All replacement
system boards for your computer have the SATA operation set to IRRT mode by default. If you have installed or deployed an image in a different
SATA mode (ATA or AHCI), there is a risk of data loss upon boot, which may require you to reinstall the operating system. For more information
on setting the SATA mode in the system setup program, see the Dell™ Technology Guide on your computer or at support.dell.com.
NOTE: If you are replacing the system board, the replacement kit for the system board includes media that provides a utility for transferring the Service
Tag to the replacement system board. Make sure that you run this utility before flashing the BIOS.
