First, let me recommend that you visit the Yr2000 web pages on Jazz (at http://jazz.external.hp.com/year2000/index.html). From there, you'll find a link to a page that lists all the Yr2K patches associated with both 5.5 & 6.0. Perhaps you should consider going up on 6.0 & obtaining a few reactive patches from HP's Electronic Support Center (at http://us-support.external.hp.com/). Both releases are very good. 5.5 will be supported through the year 2000; 6.0 will be supported significantly longer than that. Jon Cohen Commercial Systems Division Hewlett-Packard Steve Hammond wrote in message ... I am about to take delivery on a 917 to do Y2K testing. It will have 5.5 on it. I was going to immediately load 6.0 to do the testing. Now I have been told I should go to PowerPatch 6, instead of 6.0 since PP6 is more up-to-date than 6.0. Or I should wait for the first PowerPatch of 6.0. Any ideas/opinions. thx steve hammond
