Is that good for anything? Does the BIOS need to care? I thought hwclock

Some implementations of the RTC will auto increment the century byte on
a century roll over. I know we are past Y2K so this is unlikely to
produce a bug in practice but there is the possibility for an unexpected
change in the contents if that position is used for any other purpose.
It is a 'well known' position and can be read/written by an OS.
