Ok...here is the scope to get a bernoulli drive to work under AUX...the
first and easiest is to update to 3.0 AUX.  The Bernoulli driver that
came with the bernoulli will work under AUX and the MAC OS.  I am not
sure if the disk partitioning that came with 3.0 will work on the
bernoulli...I guess I will try it out and let you know.....

BUT lets say you do not have 3.0 and want it to work....

I have a bernoulli Dual 90....my left drive is formatted for MAC OS and I
have all my applications on it.  the right drive is formatted for UNIX and
I have it mounted under AUX as an additional storage disk....  right now
I am working under 3.0 but had it working under 2.1?  Here is how it is done..

first you will need two utilities that did not come with the bernoulli drive
the first is CMS Utility 6.0.1.f  this program is going to partition your 
bernoulli disk....the other is SCSI READ.. This is a control panel utility
when set up mounts the bernoulli onto your desktop if it is for mac stuff...

So now determine how you will use your bernoulli  MAC OS or UNIX...I never
tryed to do both...maybe an interesting experiment.

Now format the bernoulli using the Bernoulli format disk that came with
the bernoulli system.  Next you will have to partition the drive using the
CMS utitility.  I partitioned it either full UNIX or full MAC OS....then
here is the difference depending on the partition.

IF it is full MAC OS.. the bernoulli driver in your system folder will not
reconize the drive and will ask to reformat the disk.  So you have to take
the driver out of your system folder.  Use the SCSI read utility to mount
the bernoulli.  Automount it afterward....Now when you start AUX the drive
will be usable....The mac drive will not be usable if it is not seen on the
desktop of the MAC OS BEFORE your start AUX.....

IF the BERN. is full AUX....it will not be reconized under the MAC OS and
will come back and ask to EJECT.  EJECT it and pull it out...then start
AUX....when the title screen comes on push the bernoulli back in...

Now you can mount the drive in AUX... I have the following in my /etc/mount
files
no not /etc/mount..../etc/fstab......

/dev/dsk/c5d1s0  /bernoulli  5.2 rw,noquota           1 2

so i have the bernoulli at SCSI 5 and it is in drive 1(d1)  slice 0(s0)

for a single bernoulli is may be c5d0s0.....

I do not know how to send MAC applications over email and i do not know
if these utilities are Public Domain.....if you know the answers let me
know and we can get you the utilities.....

note:  A huge help in figuring this out was Antonio and Rodney at the
A/UX software support line......
