Yes of course, my bad

The thing is that disk geometry is actually (physical geometry, reported by the 
disk controller) and here
bios geometry stands for the geometry reported from bios int13.
Also “bios geometry” === “logical geometry” === “lchs”.
So following previous discussion with Gerd, maybe CONFIG_HOST_BIOS_GEOMETRY is 
better?
