peculiar boot options screen

I use Suse Linux 11.1 on a VMware Workstation 6.5.3, and I’ve run into the following strange behavior: occasionally (happened two-three times in the last several days), I get instead of the usual boot options screen, which is of green color, a screen with the same content but which is predominantly blue; in fact it contains a sort of snowscape with a penguin walking across it. So far I haven’t noticed anything wrong with my machine; but I’m curious if anybody else has noticed it. Could it be some malware?

It’s normal at this time of year. It’s not Viri or malware. Relax, it’s just a bit of fun.

Thanks. I’m relieved. bostjanv
