Thank you for the answer,
i will use the array created with mfiutil...

Just for confirm, i´ve made more tests and more one time the array from
bios still stay with secondary raid level = 0 when creates a raid 10.


Creating with mfiutil, OK...

mfiutil create raid10 e1:s0,e1:s1 e1:s2,e1:s3
mfiutil name mfid1 DADOS

noname# mfiutil show volumes
mfi0 Volumes:
