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! - MJB -

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. -- Perry Kivolowitz, ASDG Inc.

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. Michael H.
