While I understand that you are somewhat of an insider to the HP/Compaq/DEC 
Alpha stuff, I just have to wonder why my AS2100 shows the 53C825 card I just 
put in it, and shows the devices on that bus.  Console shows version V5.0-75.  
AS2100 4/275 4CPU.  Don't have a serial console line, so the following is 
retyped:

During boot:
bus 0, slot 1 -- pka -- NCR 53C810
bus 0, slot 6 -- pkb -- NCR 53C825

Booting under Debian without the two wide drives in is fine; I just put the 
825 card in with two drives, so I'll have to readjust my booting.  Although I 
want the boot to be onto the RZ2DD-LS anyway since it's the fastest drive in 
the beast right now.  Under the Debian 2.4 kernel I'm running (which is 
custom compiled for Sable SMP) the 825 comes up as scsi0 and the 810 comes up 
as scsi1.  I'll have to move some drives around, dd over to the RZ2DD and 
reboot, I guess.  Or just reinstall... :-)  What I will do first is move dka0 
to dkb0 and see if it will boot and run. 

Ok, have swapped disks around, booting....

Booted fine on the 53C825 controller on a narrow drive.  Dmesg snippet:

I almost didn't attempt this controller due to the statement that the 825 
wasn't supported by any SRM; maybe that was just for the pc164 perhaps?

Man, gotta love the SBB drives, so easy to move around.  Too easy, I guess, 
since the device names change if any singe drive is moved.....
