Between _every_ boot? How do the bytes change every time in 5 boots? Are
bytes just increasing?

Yes, shadow handling seems to work fine. The BIOS has _some_ reason to
change it's config (which is far bigger than the 256 bytes of nvram
nowadays, --> ESCD/DMI)

Have you changed the configuration of the machine? (Enable/Disable
Floppy, ...?)

Can you please observe the changes over several consequtive reboots (5
or so)
