This is blogged because it is surprising. Some months ago my friend and me were investigating Mac OSX for my WebOS, so we installed the latest version on a machine, SAMSUNG R25 XE04 with a T2330 Dual Core CPU. After that, Windows 7 was installed back. However, Windows recognized his laptop as a Solo Core CPU.

Obviously the resolution is to refresh / update the BIOS. We searched the Internet for this, and found a number of people having this problem. It is hard to understand why could this happen.
