Why can I use a keyboard or mouse while installing a Microsoft® operating system remotely by using DRAC5 Console Redirection?
When you remotely install a supported Microsoft operating system on a system with Console Redirection enabled in the BIOS, you receive an EMS Connection Message that requires you to select OK before you can continue. You cannot use the mouse to select OK remotely. You must either select OK on the local system or restart the remotely managed system, reinstall, and then turn Console Redirection Off in the BIOS. This message is generated by Microsoft to alert the user that Console Redirection is enabled. To ensure that this message does not appear, always turn off Console Redirection in the BIOS before installing an operating system remotely.
