They don't generally.

Some people used to write the oopses into video memory, but that
is not portable.
I wouldn't think most BIOSes these days would bother to clear system RAM
on a reboot. Certainly Microsoft was encouraging vendors not to do this
because it slowed down system boot time.to

Reset button is like a cold boot and it generally ends up with cleared RAM.
