The new RSOD
Are you sick of the BSOD (Blue Screen of Death)? Well, get ready for the RSOD, a new feature of the Longhorn. Word of the new Red Screen of Death has been floating around the Internet for some time now. From what I can tell, it doesn't completely replace the Blue Screen for all STOP errors - just the really bad ones (I've still been able to generate a BSOD in Longhorn). I'm sure we'll be seeing more of this one as time goes on...
apparently RSODs will be for boot loader errors and what not....probably gonna help us tech guys out alot in narrowing down some of this stuff
