/dev/nvram

dd if=/dev/nvram of=nvram.img bs=1 count=114

That rips a copy of the CS5536 nvram.  /dev/nvram skips the actual clock 
registers.  So the byte indexes don't exactly line up with the indexes 
you would use via port 0x70/0x71 IO.  Something to note when lining it 
up with the docs.

Edit with a hex editor and flip the of= if= args to write.
