My colleague Dennis Abbott has been busy adding content for the DellTechCenter Chat today - Check out this brand new page for Enabling WOL using DCCU and Software Distribution. Basically, the DCCU allows you to query and configure Dell BIOS settings using an executable in Windows. You can use that executable manually, our push it using SMS, ConfigMgr, or any other software distribution tool.
oh yea, and did I mention it's free?
