hello i think this bios have allready 2.1 slick maybe you mus reset service tag try update bios from dos envroiment from windows sometimes update don't work and you disable update the same version of biuos from windows too
I bought the PC without an OS, so I need to put a valid SLIC in there I guess. I don't really get the reason to change the SVC Tag number. If there is a SLIC preinstalled, is that checked against the current SVC Tag? Thanks!
If you bought machine without OS there is no Full SLIC that is why you would need to use the SVC Tag tools. Have you tried running slic dump toolkit to see id you do have slic.
Also Windows 7 Loader from the MDL Projects and Applications thread will show whether or not SLIC exists and if so what version.
