Where are you guys getting this info. This is not to quarrel, but, my current 
experience directly contradicts, I think, several things being asserted in 
this thread. I've got two SuperMicro SuperServers here running with Nvidia 
Nforce chipsets and NVidia SATA RAID. Both have been configured with two 
mirrors apiece. One mirror in each is dedicated to the OS, and the other to 
data. Due to some recent issues, and to a decision to shrink the OS partition 
on the system mirror, I ended up booting both of these machines into Linux 
using hte gparted distro disk. There was no problem. According to the second 
post in this thread -  "Every motherboard-based RAID solution is essentially 
software RAID (provided by a windows driver) in combination with a BIOS patch 
which allows the system to boot from the disk array." - that statement seems 
to be in direct contradiction to my experience. I'm assuming that no windows 
drivers are involved once I boot off the Linux gparted distro CD, or am I 
missing something here? The boot-up did involve options to configure 
additional drivers for RAID, and I picked the Nvidia mirror drivers - but if 
the Linux Nvidia drivers can 'see' the mirrors I created in Windows, that 
would also seem to contradict some statements being made in this thread...no?
