Booting from RAID

[Kevork]

Hi,

Could some one please give me some help about how's the better way to boot
from raid ?.

I think hardware raid is better when  trying to keep booting from raid, is
this correct ?.

I have an Intel mother board, that have some raid function when using SATA,
but I read on other post that it is not entirely hardware, but even so,
won't be this better than software raid when booting from raid is expected
?.

The idea is to use raid 1, such way to get system running, or even to boot
it, when some partition or entire disk fails ... would it be possible ?.

Thanks a lot,
Kevork.
