You can access CMOS RAM by writing the address to port 0x70, and
then reading or writing data to/from port 0x71. The only gotcha
is that you'll need to write a small app to do it, and to also
calculate a new CMOS checksum. I dunno what the alg is but
probably simple. Also there is /dev/nvram which might help but I
haven't looked at it's interface.
The motherboards will likely have to be identical on all machines
for this to work also, with similar hardware configuration.
