Based on the suite of software you mentioned to run under DV, you better get
4-8 mb memory and a 25 mhz 386.

Unless you just have to have the 20 inch, you might be happier with the super
high performance 16 inch models from various vendors. I use a NEC 3D (14
inch 1024x768 max) and have been very pleased with it. Be sure you check the
brightness on the monitor. Many good looking monitors are lacking in reserve
brightness. The Sonys and Bendix are bad about this.

Whoa, Don. Say that AGAIN. Is that an undocumented thing from QuarterDeck?
My manuals are at the office so I can't look it up, but I sure don't remember
it. What does NR do? Your message is the first I have heard about it. Is
it supported under QEMM v4.23 or is it only in your new version?

Depends on your system. When I got my new 386/33 (with 16450's, not 550's), I
did some tests with RBcomm and with DSZ. RBcomm had no problem keeping up
with 57600 bps receives without flow control. DSZ couldn't quite handle
57600, but did quite nicely at 38400 (3550cps on the one file I tried). All
my tests were run under DV2.22+QEMM4.23 with no other windows open.

Well, take a look at this message. It ain't from me and he knows what he is
doing... I think I learned a little more from Ken's messages.

Subj: 386SX Motherboard
This is a follow up message about the 386SX motherboards Robert. Over the
weekend, I installed two 386SX motherboards as well as a 286 motherboard.
What a pain.... With the 286/12 motherboard, we experienced modest problems
with the hard disk controller. As I told the owner of the system, it was
clear that we were not praying to the correct gods. Be that as it may, we
had it working by Sunday night. For the first 386SX motherboard installed,
two problems occurred. First, the case to be used was an AT case, drilled,
etc for mounting only an AT sized motherboard. The particular 386SX board
installed was instead, an XT sized motherboard. Despite my objections, the
owner decided to sort of set the motherboard in place on foam strips and use
the boards installed in the slots to hold it in place... I certainly hope
he corrects this problem at some point or another, but in the meantime, it
appears to work.
Problems were also encountered when installing my own 386SX mother. The
actual installation of the board required about 45 minutes, including
carefully noting what wires went where, removing all cards and the old
mother, and the opposite process for installing the 386SX. After this was
done, I found that the video card I was using was too slow to operate properly
in the system. It's a very old Hyundai thing, which saw life first in a
4.77mHz Blue Chip system. I spent $30 to get a new mono adapter, which worked
much better, and gave the old one to a friend. The second problem occurred as
the result of using QEMM in this system for the first time. In my haste, I'd
forgotten to tell QEMM to exclude the area of memory where the network card
lives, so the network software refused to function. This was my fault, and it
took me a while to figure out what I'd done wrong. The final problem related
to a bad chip in one of the simms. The system wouldn't run for more than 3-4
hours, and had to cool for some time after that. Since this was discovered on
Saturday and I could not replace the memory until Monday, my BBS was down
from then until Monday night. The upshot of all this I suppose is that while
installation really was quite easy, the few problems encountered I think were
significant. Had I lived in Northern Saskatchewan and was conducting all
business via mail order, it may have taken considerably longer to correct the
problems.
As to whether or not the board functions adequately, and whether or not it
was worth it, I think the answer must be yes. I was able to sell my 286
motherboard for $200, with the 1meg of memory on it. I can't tell you how
little I really paid for my new motherboard and memory, but I can say that
the list cost was $380, plus I think, $180 per meg for 256x9 simms. So using
list prices (that is, what HQ computers normally sells the stuff for), my
final cost would have been $360. Plus tax. Cheaper than an All Charge Card I
think.
What I actually purchased was a 386SX board with clocks of either 16 or 20mHz
selectable. Since we're dealing with an SX (a system that accesses memory 16
bits at a pop) I was able to go with 1.5megs of memory, an ideal size for the
BBS. For a real 386, I would have had to go with either 1 meg or 2 megs. The
SX system interleaves memory on a 512K basis it seems. At least, I discussed
the matter with HQ, and that's what we decided. If this is the case then, I
must have 1 meg running with no wait states, and 512Kb running with 1 wait
state... I think. In any case, I use 320Kb for a small ram disk, 64Kb to
shadow the bios (but not the mono card's video bios), some portion for loadhi
support, and have about 900Kb left over for applications. This is enough for
me to run four copies of my BBS program, or three copies, the network
software in server mode, as well as hae a 64Kb dos winodw open for file
copying, etc. BTW, the ability to run the network software (Lantastic) as a
task under DesqView is unique to 386 systems. It is not possible to do this
at all on a 286 system it seems (I never had any luck at that, and messages
appearing here now and again seem to indicate that it cannot be done).
The particular 386SX motherboard I purchased doesn't have a brand name on it,
nor on the box, nor in the manual. It is made in Taiwan however. In spite of
this, the manual is written in a pretty good imitation of English. It is
equipped with an AMI bios. Things that I was able to LOADHI include 30
buffers, the network netbios driver, the network "redir" program, two copies
of WatchKat, OpusCom, the Dos Share program and VDisk driver.
The Chips and Technologies MIPS.COM program indicates that the "overall mips"
rating is 2.31. If I use the PD Speeder program, the rate changes to to 2.41
mips. This compares to a true 386/20 mip rate of 2.50 without speeder, or
2.54 with speeder. Note however, that the 386/20 had only 1 bank of memory,
so was not interleaving it. The Mips program compares the system being tested
to a Compaq 386/16 on its own, and the average speed compared to the Compaq
was 1.17 times as fast. Again, this particular 386SX is pushed to 20mHz... I
think the cost/performance breakdown compares favorably to a 386/16 or a
386/20... The Landmark program I consider to be crap, since it
over-estimates a given cpu's performance by comparing it to an IBM AT defined
to run with 1 wait state. This sorta seems to be to be like comparing a
porsche running on five cylinders to one running on six, and saying the
latter is operating at 120% efficiency... It seems to me that the latter runs
at 100% efficiency, so that the five cylinder model might instead be running
at 80% or so, not the other way 'round... None the less, Landmark is used all
over the place in ads to tell folks that XYZ dealer's 386/33 is running at
55mhz. Using Landmark version 0.99, I got results of 25.5mhz. From Landmark
2.00, I got 24.3mhz. Note that most dealers use Landmark 0.99, no doubt due
to the better lies it tells.
The motherboard itself has some pretty artwork... The 386SX chip however, is
a surface mount unit (soldered on, or built in) and looks somewhat tacky
compared to the rest of the motherboard. I don't know how compatible it is
with every little thing. I did have my daughter's EGA display on it for a
while, but didn't run any games or anything. It does seem content to run all
the previously mentioned software however.
Two oddities were none-the-less observed. When I ran version 5 of the PC
Magazine benchmark programs, the previously mentioned Speeder program had a
negative impact on performance measurements. Speeder is a program which
changes the memory refresh rate. Other similar programs are around under
different names. While performace measurements under the PC Mag tests is
degraded by this program, the Mips program shows an increase in performance.
I do not know what this means. Also, as a test, I wrote two dummy programs
which do very little. The first program checks for a keypress and if none is
found, gives up its time slice to other tasks running. The second increments
a counter and also gives up time to the other task. The intent of these
programs is to measure how rapidly one can swap DesqView or DoubleDOS tasks
on a given system. On a 386/25 with 8 megs of memory, I measured 75.9 task
swaps per second, with the bios shadowed. On the 386SX, without bios
shadowing, 86.7 task swaps per second were observed. The only thing I can
think of is that maybe the extra memory on the 386/25 is slowing things a
bit. Oh yeah... I found that I did have difficulty running an older version
of DesqView (2.01) with QEMM, in spite of having told QEMM "olddv". No big
problem... switching to a newer version of DV cured that. And yet another PS
sorta note: I've

Subject: Re: DV VS WIN386
Brice,
Thanks. As I use Windows more and more and discover how "buggy" it really is,
I think about trying out DesqView. Since you mentioned it, I have some
questions for you about DV. First of all, can you run it with a mouse in the
same way that Windows works, like moving windows and resizing them by
pointing. Which version shoulI look for and with what add-ins (I've seen
QEMM advertised with DV, is it necessary when I'm already using HIMEM) ? Can
DV be run inside Windows the way you say Windows will run under DV? Does DV
come with any extra applications like, in Windows, a card file w/autodialing,
clock, etc. or would I have to run these type programs in a separate window?
I would appreciate your help. Thanks.
