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. Jeffrey Buchsbaum send email to: jeffb@eleazar.dartmouth.edu

I have a weird problem (and my
posting got garbled yesterday...
sorry). I have a macceletor board
from National Semiconductor and
when I use it I lose my extended
keyboard at startup and shutdown
is messed up (macII monitor led stays
lit). If I bypass the board, all is well.
The board worked fine with only one
scsi external and one internal. Now....
I have two externals (addresses 4 and
1) and an internal (default apple 40
meg quantum at address 0).
To get everything to work, I have to
start the external disks after the mac
and then restart to get the two externals
to mount. Scsi tools cdev does not help.
In fact, if the power to this one drive, the
newer one, is on before the mac, no key
input....and shutdown waits for the drive to
die before finishing. If the drive is off, the other
external drive is ok, mounts, and I have key
input. Both externals are Seagate ST296NUs. I
have two terminations, correctly set up:
Mac:old seagate(terminator):new seagate(no terminator)
:scsi card(no terminators):internal quantum(terminator)
I just want to avoid two restarts. The cirrus init does not
help either (remounts scsiUs later in startup sequence>>).
Any help would be appreciated. I hope this posting is
not garbled. My tcp/ip host uses non-standard
9600 baud modems that are really noisy (JHU). Sorry
to have wasted bandwith yesterday.
Many thanks to Werner Uhrig from Texas. Your help
has been fantastic. I cannot understand how your
rn got my posting, while my own got
gibberish, to say the least..... Thanks Werner.
