Do not install PERC 3/DC and PERC 3/QC controllercards in slots 6 and 7. Expansion cards with older PCI technology might overload the newer133-MHz PCI-X slots (slots 6 and 7), which have a lighter signal load due to a shorter bus and onlyone slot on the bus.NOTE: "Overload" in this context refers to the signal load, not the power load. All the PCI slots receiveequal power from the same source.See your Installation and Troubleshooting Guide for information about installing expansion cards.Configuring RAID ControllersNOTICE: Changing the configuration of the ROMB controller on the boot drive by mistake can result inclearing the operating system configuration.If ROMB is enabled and one or more PERC 3/DC or PERC 3/QC RAID controllers are installed inthe system, do not change the configuration of the ROMB controller on the boot drive by mistake.When you access the RAID controller setup functions by pressing during startup,the ROMB boot drive is listed as the default controller.
