CMOS viruses are real - no doubt for me! I suggest to contact McAfee or the
like for more detailed answers - there are quite some large virus families
with cmos subtypes! Depending on the cmos chip there is more or
less 'waste' space, not used by the bios, which can be used by viruses if
the space is sufficient!
