Removing previous Fedora kernels…

i currently run Fedora 12 with the latest stable kernel update.
Heres the command steps l took to erase the 2 kernels l dont need.
Its always a good idea to have a fall back previous kernel available if needed.

SQL 2008 Reinstall nightmare..

Trying to un-install a Microsoft Heros event 2008 release of SQL Server 2008 on my Windows 2008 server box but each time l uninstall it and all related components, on trying a fresh install for a default instance l keep seeing the previous default MSSERVER instance.
Heres the link to Mark Michaelis Weblog which has hacks on forcefully removing Sql Server 2008 using command line as well as registry hacks. http://mark.michaelis.net/Blog/SQLServer2008InstallNightmare.aspx

Finally, after running all the steps in his blog, l ran the Installed SQL server discovery report from SQL Server 2008 installation center (under the Tools section) and l found l have succesfully removed the instance.
