you don't understand my question.
I want to know if it is possible to have more than 8 partitions in the
disklabel ?
for example : sd0a, sd0b, sd0c, sd0d, sd0e, sd0f, sd0g, sd0h, 
and now for an extra disk, I need an other partition, sd0i.
I need this for my 5th msdos partition.
or in a last use, is it possible to make it on disklabel sd1?
