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.
