Ok, thanks for making that clear. Can you provide some timeframes?
Ie. how much later "later" means, and how much time passes between
"later" and "suddenly" ? :)

The reason this may matter is that special configuration of chips
performed by the factory BIOS may well stay around in chip registers
even if power is cut for some time, while if the special config is in
CMOS it will of course survive without power a lot longer.
