Apparently the Chernobyl (aka CIH) virus _has_ struck.
BUT the good news, at least for followers of this thread, is: if your PC can
boot (or indeed display any message at all), you most likely don't have the
CIH virus, because it trashes your CMOS. I suppose it might trash your disk
instead if it has trouble writing to the CMOS, but I haven't seen that
mentioned on any of the A-V sites I visited.
