Yes, but my question is about how md cooperate with the BIOS in this case ?

Not sure what you mean. When Linux runs, with or without MD, no BIOS
code is ever executed.

Ok I think I'm missing something more fundamental here.

For exemple when writing to the disk, each write goes into the 2 disks
in case of RAID1. When Linux runs, is it either DM or MD (and
necessarily one of them) that does this work ?

Yes.

For windows case, does it relies on a driver that is provided by the
RAID manufacturer ?

Exactly.
