Just install off 5.5 and then once the system is up/running update with 7.4<BR /><BR />hope this helps Tue, 07 Feb 2006 14:11:25 GMT Mike Bollman_1 2006-02-07T14:11:25Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/smartstart-version-query/m-p/3726335#M49887 I personally think my case it is a hardware issue. Apparently SmartStart 7.40 is listed ono the support matrix for ML570, but it's not. I only got success using SmartStart 5.50.
