 Good day.

 Please help. I have a motherboard that  has a SATA
 RAID support. I enabled it and configured the RAID
 using RAID1   through the BIOS. My question is, do I
 also have to configure RAID1 in FreeBSD so that it
 automatically mirrors what is in the first disk or my
 hardware RAID is enough?

 Thanks,

With all RAID, you either do software or hardware. Since your drive controller 
supports RAID, the array will look like any other disk to FBSD. You just 
treat it like another hard drive. 
One thing to keep in mind is that a lot of onboard SATA controllers that 
support RAID actually do so through their driver. Meaning its not really 
hardware RAID. If the SATA controller only shows that it supports Windows, 
then it is very likely not truly performing hardware RAID, and won't do 
anything for FBSD. 
If thats the case, then you can use FBSD to create a stripe. You pretty much 
just add a kernel device, and do some simple config work. There is a good 
howto for that on the FBSD handbook site.
