Has anyone encountered this problem before? I've used the same Ultimate DVD for 5 systems prior to this one. All installed fine. It's an exact copy of the Microsoft one. Checked hash and everything tallied. The motherboard's a Zotan G41 Value. BIOS says sometime in August 2009. Didn't remember what version it was but I was wondering what would happen if we tried to install Windows 7 Ultimate on a system without a SLIC 2.1 table in the BIOS.
