echo dma on > /dev/sdXY/ctl

see in sd(3).

Kfs is the older disk file system for standalone terminals and the like.
For most purposes, fossil replaces it. Fossil is user-mode, while kfs

You will usually need to be hostowner. See in cons(3). (And also
kprint there, for

My first guess is to ensure you haven't overlapped partitions or
