You need to increase the kernel paramater NDISK - This is incorrectly
documented in the Xenix admin. guide as number of floppy drives but
is in fact the number of hard drives.

Of course the address and interrupt must be changed for the
second controller. You may have to run a wire from the mother
board to the interrupt track on the second controller if it is
not fitted with a track on the edge connector.

This setup works well here with two WD1006 RLL controllers.
