I have been meaning to ask whether people here use the DMASnoop
program that is supposed to improve reliabilty of SCSI stuff. Do you.

I will be fitting a SCSI CDRW to my AB'd Falcon soon and seeing as it is
internal it will be on all the time. Up to now I have only been using my
SCSI SyQuests occasionally, so it is off most of the time, and have
been using the DMASnoop program and low bandwidth resolutions to
improve things.

I will be backing up my HD prior to the CDRW/Eclipse/big HD fitting so I
will be very careful with my SCSI.

Hopefully this week will be good for at least two Eclipses in Europe :-)

My Falcon very rarely (if ever) boots 1st time from cold. It will lock up
at some point during the auto folder sequence. So I always wait a
couple of seconds after powering up and then reset after that it is
fine. In fact with the original 68EC040 in my AB it would boot cleanly
from cold but was very prone to crashing for the first 10 minutes or so
if you made it work hard. I would just power it up and then leave it
alone for a while.
