	I have a problem with my macII that has me puzzled.  My set up is as follows:

MacII with scsi disk 0 hooked to
scsi disk 5 (Seagate) hooked to
scsi disk 4 (Cirrus) hooked to
Maccelerator nubus board (serves as 
a terminated scsi device, not active
due software hold up)

	Here is the problem.  If all devices save the mac are turned on first, then I start up the mac, I lose the keyboard and the Seagate only starts to spin up at the macUs power-up while the Cirrus is already spinning.  If I restart, the Seagate is on the desktop, but I still have no keyboard response.  The mouse attached to the keyboard is fine (apple extended keyboard).  If I then go to shutdown the mac, the monitor and mac will not actually powerdown until the power to the Seagate disk is turned off.  The 





screen of the mac does get dark, though.
	If I start up the system without the Seagate on at all, all is well.  I can then power up the Seagate and restart.  But this is a pain.  To have  a keyboard, the Seagate must be off as I start up.  The Cirrus can be on or off, and the system does not care.  
	My only guess is that the Cirrus is internally terminated, and this is Rmessing everyting up.S   The Seagate is not.  What should I do, and why the heck are the keyboard and shutdown sequence screwed up.  I am writing this in Word right now, with the Rpainful, two stepS set up having been used.  Excusing my poor grammar, could anyone please help me as soon as possible.  I hate weirdness in my system.  If the Cirrus is at fault (internal termination....), how do I correct this?
	I know the Maccelerator board is not at fault since it worked before I introduced the Seagate.

Thanks in advance.
