Sw#1 is DMA enable/disable.  Open is to disable DMA.
Closed is to enable DMA.  DMA may need to be disabled
for some memory cards.  You currently have DMA set
to off.  This will slow down SCSI devices.  What is the
name of your 4MB memory card?  It may not be
necessary to turn off DMA.

Your SCSI ID is 7.

Here's the table:

For each SCSI ID, Switches 2, 3, and 4 must be set to:

SCSI ID=7  closed,closed,closed
SCSI ID=6  closed,closed,open
SCSI ID=5  closed,open,closed
SCSI ID=4  closed,open,open
SCSI ID=3  open,closed,closed
SCSI ID=2  open,closed,open
SCSI ID=1  open,open,open

I recommend setting SCSI ID to 2.  That's because according
to Quantum, the ProDrive 240 requires a spin-up delay.  SCSI
ID of 2 is special to the Apple High Speed SCSI card.  It
makes the computer pause on startup to let the drive spin up.

Which slot is the ProDrive in?  Is that slot set to "Your Card"
in the control panel?  If not, it needs to be.

Also, Apple does not set up its System 6.0.1 boot disk to
include the Apple High Speed SCSI drivers.  These drivers
are in the System/Drivers folder on one of the System Tools
disks or the Install disk (I forget which one).  You need the
SCSI Manager and the SCSI HD files copied to the Drivers
folder inside the System folder of the boot disk before any
GS/OS program will recognize the SCSI drive.

Also, make sure the SCSI ID of the ProDrive and the SCSI
card do not overlap.

Adv Disk Util is the right program.  Just make sure the
SCSI Manager and SCSI HD files are in the Drivers
folder inside the System folder of your GS/OS boot disk.

Good luck.  Please contact me or the newsgroup if you
have any further questions.
