I recently attempted to use the 7.4 version to update the bios on my R710. All was good until after the bios update completed successfully and then displayed a notice to restart the system for the update to complete. However the default xterm user "vuser" does not have root privileges to reboot the system. An attempt to "su - root" failed with 'linux' and 'dell' as the password. So I simply performed a warm reset within the drac session however the bios update did not take affect.
For those of us not familiar with CentOS or the TWM desktop could you provide an easy way to perform a graceful system reboot?
