Just to let you know I updated the A17 bios for the Dell Inspiron 6400/E1505 to Slic 2.2. It installed fine on my Dell 6400 and I ran the Slic Checker which showed the Slic version to be 2.2. I haven't rebuilt my lappie to Windows 8 from Win7, as I simply haven't got the time currently. If anyone wants to try it then reply to this thread. I'm unable to post a link as I have not got a post count > 20.
