This would  make the first partition active, non-interactively,  
leaving mbr as is.
fdisk -0fa /dev/wd0d
and this would put it back.
fdisk -2fa /dev/wd0d
It also removes active from previously marked partition, having more  
than 1 partition marked active can be a problem, some fdisk's let you  
do that, netbsd's doesn't.
You could also do
fdisk -a /dev/wd0d
To change active, interactively.
