I recently got ahold of a PE 2650 and am attempting to configure the physical drives. When I use CTRL+M to get into the PERC/CERC BIOS Configuration Utility and attempt to switch the drives from ready to online by pressing space, I get the message, "Drives not-responding cannot be selected. Press any key to continue." The status indicator lights on all four drives show solid green. Do I have a hardware problem or am I missing a step in the configuration?
