Sb: #Everex EGA in TX

Good news, bad news.  EGA in my TX.

Good news:  I received my MultiSync II and Everex EV657 (max resolution 800 x
600) super EGA today.

Bad news:  The EV659A that I traded (max resolution 640 x 480) has one more dip
switch than the EV657.  The dip switch to shut off the auto-switching.  On the
EV657, the autoswitching cannot be disarmed like it can on the EV659A.

Good news:  Both boards can be set to auto-switch on IRQ2, IRQ3, or NMI.

Better news: The Everex 800 x 600 driver displays Generic CADD Level3 properly,
even though the MultiSync II is only supposed to do 800 x 560.

More better news: I've only noticed one glitch after switching from 640 x 350
to 800 x 600 and back again - The control-alt-delete combination doesn't
re-boot the machine properly.

Great news:  I found a program over in Library 3 of the PC Junior Forum (GO
IBMJR), named SAVENM.ARC.  It's a TSR program that's supposed to restore the
NMI vector if anything corrupts it.  Apparently, this is common on the PC Jr. 
I installed it, and whadaya know?  The control-alt-delete works again.

Other info:  Everex makes 3 EGA boards in the Micro-Enhancer series:

EV657 - Also called Micro-Enhancer II.  Max resolution 800 x 600. 
Auto-switching cannot be disarmed.  Hercules emulation can be disarmed.  VGA
emulation is external software.  Has parallel port that can be disabled.  I
don't know if it comes with font software. (I didn't look, and it's at work).

EV659 - Max resolution 640 x 480.  Auto-switching can be disarmed.  Hercules
emulation can be disarmed.  VGA emulation is built into the BIOS.  Comes with
22 EGA fonts.  Has parallel port that can be disabled.

EV659A - Identical to EV659, except it has no parallel port. Saves about
$15.00.

I keep everyone posted.

At last, I seem to have the Ctrl-Alt-Del working on my TX
with the Everex EV657-1 EGA card.  I got a copy of INTVID.COM
from the EGA utilities disk at a local Radio Shack, load it
from my Autoexec.bat file, and I found that if I turned dip
switch #5 ON on the EGA board (Full Hercules and CGA
Emulation), the Ctrl-Alt-Delete started to work.  You still
do get an occasional lockup, but the incidence now is similar
to what I get with the CM-11 on my other TX.

My older game programs (Flight Simulator 2.14 and F-15 Strike
Eagle) still won't run on the EGA, but everything else now
works.  Autoswitching is really nice, since I'm running
Generic CADD Level 3 on this setup and the 800 x 600 mode is
spectacular.  HOORAY!
