Re: Can v. 112 of Jumbo U2 Crash OS/2 ?

["Steve Crutchfield" SCRUTCH@xxxxxxxx]

If I recall correctly, SDD comes with a utility to un-install back to
vanilla VGA. I recommend using that utility rather than the Alt-F2 at
boot, then hit V to revert to VGA method. Once you've uninstalled,
Reboot, and then reinstall your earlier version of SDD. Kludgy and
klunky, but it should work.

You're right.... trap E is a rare error. In my years of use of OS/2
I've found it usually means a display driver problem.

Steve, thanks much for your reply. Now that you mention it, isn't Trap
E
one of the rarest traps for most users ? I don't recall ever seeing
one
before . . . unless it was way back in the days when I had an ATI
card in
this box. Their video installs were the pits ! Some of their cards /
drivers had serious problems with certain versions of PMMERGE.DLL,
under
the wrong circumstances. When I put the Matrox G400 in a couple years
ago,
it was a drastic improvement ! Maybe not the ultimate in performance,
but
I'll trade a lot of _that_ for stability, any day.

Here's the kicker: I upgraded to the SDD Pro eval. on 7/19. For 2 or
3
weeks prior to that, I was running the free, non-Pro version of SDD
that
came with ECS. I still had v. 110 of U2 at that point, but no crashes
either.

One of the tests I'd like to do is to see if / how I can backlevel to
the
earlier SDD.
