[comp.sys.amiga.tech] Escort2 & vd0:|RAD:

MJB@cup.portal.com (Martin J Brown-Jr) (01/20/89)

I've got an Escort2, from Expansion Technologies, with 2megs in it. I like it
well enough, EXCEPT, neither vd0: or RAD: will survive a warm reboot via 
C-A-A. It will survive a warm reboot caused by a GURU. I called Expansion Tech
about this, and their response was that it just depends on the particular
A1000 it is hooked upto. On some machines, a C-A-A will work and on some it
won't. They said that also, some times doing a C-A-A real quickly will work on
those machines that normally C-A-A won't work on. The real quick method has
only worked once. This A1000 has worked properly in these respects with an 
ASDG Mini-Rack. This leads me to believe that the Escort hardware design is
not upto snuff.

Can anyone shed some light on this? Since it RAD:/vd0: will survive a GURU
reboot, I'm hopeful that someone on the net can lead me to a minor hardware
hack, or even more hopefully a software fix. Any ideas?? Thanx for your time!

Your problem has nothing to do with your A1000 as you have guessed.
Some Expansion Technology's memory boxes don't refresh during reset
(hence the laughable suggesting to C-A-A ``quickly''). Call them up
and ask them if your serial number (board and box) are one of those
that don't refresh ram during reset.

Hi.  I vaguely remember an article in the Transactor (from an issue
last year) about Escort2's which were losing vd0: on c-a-a's.  They
listed a simple fix which grounded something on the Escort to the
ground on the Amy bus.  I can't remember any more details, but maybe
this will jog someone else's memory.
