	RL drives were reliable (compared to RA81 and RK06/7 drives) if not 
	exactly spacious ;)

	What rev of the kernel do you have?   First line in /VERSION should
	have the magic number.

	What I think is happening is that the system is only configured for
	2 RL drives - the change from 2 to 4 happened quite late (patch #439
	I think).

	The RA problem sounds like the MSCP driver either isn't in the
	kernel or wasn't probed/attached at boot time.     You can see if
	MSCP support's present with something like 'nm -g /unix | grep _raintr"
	and seeing if you "040364 T _raintr" for the interrupt handler.   If
	you do get that then check /etc/dtab for a line like:

ra      ? 172150 0      5       raintr          # uda50, rqdx1/2/3

	The '0' for the vector says for the probe/attach logic to assign
	a vector and tell the controller what value was used.  You could put
	anything in there (154 or 150 I think is the assigned value for the
	first MSCP controller).

	If none of that works then I'm stumped as to why the RA drives can't
	be accessed.

	Good Luck.
