      Hello Janusz,
the above 64 bytes are BIOS vendor specific.
Here is a short description I found in Ralph Brown's Interrupt List:

Subject:	[OpenBIOS] PC-CMOS memory..
Hi to all in Open Bios project,
My question is not directly (yet..) related to OpenBios project but I
do hope
to find here an answer.
I am writing an embedded PC application project in which I would like
to use some of PC CMOS memory. All documentation I have found does not
seem to be correct. Especially in the area of HDD data (types 47,48).
Each motherboard I have tested seems to store this data in different
locations.
Configuration data is stored in the first 64 bytes. RTC memory
consists
of 128 (or more locations). What is stored there. Can I safely use
this memory
for my own purposes?
Thanks for comments.
Janusz
