I'm sorry.  I should have elaborated more.
 
	I Have:     A1000
		    512K Memory (all Chip type, standard A1000 stuff)
		    Kickstart 1.3 (v 34.5) Workbench 1.3 (v 34.20)
		    PAL's are NOT grounded yet.
 
 
The A1000 goes through Kickstart fine.  It then requests a Workbench disk
instead of booting off of the A590.  After booting the computer from a
floppy, "binddrivers" brings the A590 to life.  After learning that my DIP
switches are set correctly, and their functions, I think the problem lies
with the Rigid Disk Block.
 
But I now have a different problem.....  (sheesh) After installing 512k of
memory in the A590, to bring the computer to a total of 1 Meg, the A1000
will not go through Kickstart properly.  It seems to load the image fine,
but now instead of prompting for a Workbench disk it just sits on a dark
grey screen.
 
I think I've installed the memory properly: 
 
	I changed the "amnesia" jumper to "512k"
	And installed the 4 chips in a horizontal fashion
	(the chips are in the sockets in the correct direction; with the little
	dimples matching the socket indents)
 
	OOOOO   OOOOO           OOOOO   OOOOO    O -- empty sockets
			2 megs                   X -- 256 X 4 memory chips
	OOOOO   OOOOO           OOOOO   OOOOO		
 
	OOOOO   OOOOO   1 meg   OOOOO   OOOOO
 
	XXXXX   XXXXX   512 k   XXXXX   XXXXX
 
So my guess is it is the infamous PAL grounding problem.
 
Thanks to all the people who responded to my plea for help!
(I've tried to get mail back to everyone.)
