Subject: 2nd IDE HD installation hassles

Hi there,
  I"m installing a second IDE HD on my 386. AMI BIOS (1990 I think), MS-DOS
5.0, the drives are both Quantum, the old is an LPS80AT (at least it says
LPS on it and it"s about 81-82 Meg), the new one is an ELS127AT (for the
same general reasons).

  I can replace the 80 with the 127 and it seems to be ok, problem comes when
I install them both.  I removed the jumper from the 127"s CS pins, so that
it has no jumpers, making it slave.  Then I put the jumper on the 80"s SP
pins so that it has DS and SP making it master.  The boot up is now super slow,
then I get D:drive failiure, press f1 to resume, which I do, more very slow
boot, then Drive not ready error, insert Boot diskette in A: press any key
when ready.  If I iognore this message and just space bar it on through
I boot off C: (the 80) as normal, and I can use both drives fine.  What gives?
I did the FDISK thing to create and extended dos partition on the 127, then
formatted it.  I got files and directories over there, it all runs peachy,
but slooooow boot and bull shit error messages from BIOS.

  Note that when specifying the drive type iun BIOS setup I entered Quantum"s
specs, but had BIOS assing me 122M size, not the 127M the quantum numbers
say should result. Is this a BIOS writer vs HD salesman definition of Meg
problem?  , and

Subject: 486 SLOWDOWN


I have a problem with my PC that I can't seem to resolve.  I have a
486dx 33 MHz with 8M, Seagate ST3120A hard drive, and running DOS 5.  I
have been using this PC to develop COBOL applications using
RM/COBOL-85.  Up until a week or so ago everything was working ok.  Now
the system has slowed down and I can't find anything to indicate a
problem.  The hard drive is only about 40% full, and is defragged
regularly.  I've scanned for viruses using several packages and found
nothing.  I'm hoping someone can give me an idea as to what the problem
is if I give you all of the symptoms, so here they are:

    1.  Disk IO's are extremely slow, roughly twice what they used to
be.

    2.  Cursor movement is extremely slow.  I used to be able to fill
the keyboard buffer when paging through files in edit sessions.

    3.  When I try to edit a file of any size, using the DOS editor, I
run out of memory.

There are probably other things going on, but since I only use this PC
for the COBOL apps I probably haven't discovered them yet.

Any effort to help will be greatly appreciated.

Subject: Equivalent to batch files under MS-Windows 3.1/NT?

This is maybe a stooopid question, but since I know next to nothing
about MS-Windows...:

We plan to convert a fairly complex DOS application to Windows (3.1 or,
if and when it devapourizes, NT). This app consists of a batch file
calling all sorts of programmes which produce batch files which are
then executed in order to call programmes... you get the idea.

There is no major problem converting the programmes to true Windows;
but I have been told (even by Windows programmers, albeit no wizards)
that there is no Windows equivalent to DOS batch files. Note that it is
not good enough to open a DOS window and then execute the batch file,
since this DOS batch file would have to start a Windows programme
proper. Using C programmes instead of batches and exec'ing everything
from there won't work, either, since the executables would have to be
created at runtime. Also, since the batches are fairly complex, I'd
hate to write a 'batch' file interpreter that would emulate the DOS
command interpreter.

Use of macros (instead of batches) hase been suggested to me; however,
the application cannot assume any particular screen layout (or, indeed,
the presence of any specific window anywhere). Besides, each 'batch'
(or macro) calls several programmes in sequence (starting the second
only after the first has terminated etc.); I am told macros are not
smart enough to do this.

Supposedly, some replacements for the Program Manager and some
(shareware?) utilities re-introduce batch capabilities into Windows;
but since we are distributing the application more or less widely, we
can't/won't expect our clients to shell deutschmarks for programme
manager replacements, and some of them would be frightened by the idea
of using shareware or (gasp) PD stuff.

I'm sure there's a big mistake somewhere in these thoughts; surely, a
supposedly mature OS/user interface/whatever-you-like must include a
basic functionality like that? If not, for Bill's sake, will this be
fixed in Windows NT?

Subject: Help with my 286

Hello,

  I have a 286 with 4Mb ram, a 744Mb scsi disk that hangs off a Seagate
ST02 scsi controller, I have a Trident SVGA card with 1Mb on board, a
Sound- Blaster Pro Basic, a Multi I/O which has a clock/calendar
(configured in CMOS to get the clock from the Motherboard), two serial
and a parallel port, and another serial port.

  My problem is this, when running something as basic (by basic I mean,
very little disk I/O, very little graphics, and not useing the
Soundblaster) as nethack for the PC or when I start up my diagnostic
program Checkit, my system locks up and requires a reboot.  The system
will lock up just during the process of selecting the test(s) to run in
the diagnotsic program, just lock up before I even start any of the
tests.  This is not to say it won't lock up other times (like when I'm
playing a game that is using all the things the other two don't), it
does.

  I'm just trying to pin this down to something I am running at the
time and I can't.  Any ideas?  Thanks in advance.  BTW, I have scanned
for a virus with the most recent McAff's and the first time the system
locked (go figure) and the second time it came up empty.

Subject: info, comments, etc on SuperStor

I was wanting to find out some opinions on this piece of software.
Specifically their SuperStor floppies. I have heard (and read on the
box) that you can format a floppy under SuperStor, which also installs
a small TSR, so that other PCs that don't have a copy of SuperStor
installed can access and read the disk.

The following are the limitations that I know of and was curious if
there were any others that I had missed:

     * the amount of space on the floppies depends on the type of
compressed data (text or bin) and that the max space is 5 meg (i'll
believe it when I see it).

     * the files are copied from a SuperStor HD to the floppy.

     * the files are then read only. (that makes sense).

1) Now I was wondering, could you run a program from the floppy?

2) can you make duplicates of the floppies using DISKCOPY or another
util without having to copy the files from the HD again.

       a) in case I'm on another machine.

       b) in case I make an image of the disk to place on a server to
ease the copying process.

3) Could I make a boot floppy out of the disk (cross my fingers) (I
hope that might not require a partition on a floppy --if there has ever
been such a horrid thought).

This is what I'm trying to achieve: I want to make a floppy (preferably
bootable) that would contain a small program to browse the files on the
floppy.  My only problem is that it needs to fit on one disk, or there
will be a lots of floppy swapping. the small size and portability is a
must. the ability to run an application is second. the third least
important is the ability to boot. the data files are the mother
problem.

Thank You in advance, Mark A. Stinson

164 is a memory size error (Run SETUP), CMOS  setting does not match
memory.

It has been my experience that SETUP errors are caused by one of two
things:

     1) Someone has changed the setup.

     2) With these early PS/2s and with the IBM ATs, the battery needs
to be replaced.

There could be other reasons for the 164 error, but these are the only
ones that I have come across.

Subject: MAXROUTE and PROTEL

Hi all, I'm in all sorts of trouble with Maxroute and Protel (which are
PCB routing packages for the PC).  My Maxroute-routed board is
generating a million clearance errors with Traxedit's DRC.

I extract a Protel file.  Load a strategy.  Edit the nets.  Edit the
via sizes.  Set the grids to 8 thou, off-grid routing enabled.  Use the
obstacle editor to draw my keep-in area, keep-outs and no-via areas.
Start the route.  After about 15 hours it routes it up to about 97%.  I
hand route the remaining 8 or so connections using "auto trace" and
"shove track".

A DRC from Maxroute gives the board the all-clear.  But when I back
annotate the PCB to protel, it gives millions of clearance errors.
When I check these out on Maxroute, it appears there are in fact some
errors.  For example, the ground rail passes on an angle past a pad,
and I calculate that the diagonal clearance is only about 6 uu (it's
supposed to be 8).  But many appear to be totally bogus; a track to pad
spacing is measured to be precisely 8 uu in Maxroute (using maximum
zoom and the absolute coordinates to measure it), but gives clearance
errors in Traxedit.  When I measure the distance using Protel's
coordinates, it _appears_ to be 7 uu on one side of the track and 9 on
the other, but the zoom is no where near large enough to give any real
accuracy.

So... is the problem with Maxroute, the converter from Maxroute to
Protel, or in Protel?  Maxroute is touted as THE routing package for
IBM PC's.  It cost me a lot of money.  Can *anyone* suggest why these
violations are occuring, and how I can stop them??  Time is burning,
and so is my ass if I don't get this fixed pronto...

Thanks in advance,
Tim Morris.

Of all possible causes of the memory trouble a bad chip seems to be
extremely unlikely for the following reasons:

1. The same troubles appear on two brand new computers under the same
circumstances.

2. Checkit runs fine if the system is booted without the EMM.. line in
the CONFIG.SYS, and crashes when run with EMM.

3. Thaddeus reports the same trouble on his 486 system.

Both Thaddeus and me found that QEMM does not cause Checkit to crash.
However, I have crashes under QEMM noting: " The processor has notified
QEMM that an attempt has been made to execute an invalid instruction. [
Etc. Etc.] ... Exception # 13 at 81A4 , error code 0000 [...]"

When excluding areas from EMM I can get through Checkit also, but the
system still crashes. Any ideas, reports, solutions, suspicions welcome
...

P.S. I invited a hardware guy from the company we bought the computers
from.  He checked the system, and said: this is not a hardware problem,
I don't understand about software ...

Subject: Need screen saver for DOS that is network friendly...

Several people around here have been using a screen saver (old version
of explosiv) but now they are on a novell network and the screen saver
causes some problems.  For one thing, once the screen saver has
activated and doing something on the screen, the computer will lose
connection if left for very long because the network shell can't
respond to the watchdog packets that the server is sending out.  The
newer version of explosiv fixes this problem, but has another problem
with netware broadcast messages.  If a message comes in from someone
and the screen saver is active, the only way they can get the screen
saver to release the screen is to press Ctrl-Enter which is used to
clear the broadcast message, but it doesn't say that they received one.
Does anyone have one?  Burnout is a possibility, but is really boring
(same with WordPerfect Office).  Anyone have any ideas?

Subject: Notebook Keyboard - COM2 conflict

This is my last-dying-gasp effort at solving what has been a very vexing
problem:

I own a Jetbook 386SX25 Notebook computer (same as a Magnavox). This
model has the AMD 386SXL CPU, AMI BIOS and is currently populated with
4 megs of Standard SIMM memory.  My problem occurs when running Windows
3.1 in 386 enhanced mode. Any attempt to use the internal modem (on
COM2) locks the keyboard, which then remains locked until the machine
is turned off and back on again.  Everything else continues to work,
i.e.  as long as you don't need to type anything, you may continue to
use Windows applications or even exit Windows. The keyboard remains
locked at the DOS prompt.  The problem appears to be application
independent as it happens with any comm program, from the Windows
Terminal applet to Procomm Plus for Windows.

The problem occurs even when the modem is physically removed from the
machine, leading me to believe that it is a memory conflict of some
sort.

The problem disappears when running Windows in standard mode.

So far, I have reformatted the Hard Drive, reinstalled DOS (version
5.0), reinstalled Windows, etc.......no joy.  Even the most generic,
plain vanilla config.sys and autoexec.bat offer no help.  I have spoken
with Microswift, whose support folks were very helpful, but no help
(they seem to think that I'm the only guy in the world with this
problem).  The vendor and the manufacturer's representative were also
no help.

E-mail me direct with solutions and I will edit and echo here or reply
directly here for all to see and comment on.

Any help will be appreciated.

How about using SUBST? The drive can be anywhere, but you access it
via a SUBSTed drive.

DOS does not allow device drivers to go where they please. Network
drivers patch themselves into DOS internal structures (i.e.  rely on
undocumented and unsupported features etc.) and only therefore can go
anywhere you like.

There might be some device driver install utility at Simtel20 that
loads block devices where you like from command line - I am not sure.
I tried some about a year ago, but then they seemed very unreliable
since they displayed garbage and/or hanged my machine.

>2. No size limits, and large sizes tested (I need a 16MB RAM drive).

SRDISK does this just fine (provided your XMS or EMS driver supports
that much memory). I have not had recently any change to test over 32M
RAM disks, but since there is no bug reports about it I guess it is
still working.

>3. Provides a way to copy a tree from another place on startup, and

Out of interest: What is wrong with XCOPY? Just put XCOPY into
autoexec.bat. I think you can also add

    INSTALL=C:\DOS\XCOPY.EXE \RAMDISK\*.* D: /S/E

to your config.sys. It will be run after all device drivers are
loaded.

As I am the author of SRDISK, I am planning to add something like this
into it. Copying files is not a feature that Microsoft documents
possible for device drivers.  Instead, I plan to make it possible
include a disk image into the device driver to be loaded into RAM disk
when the driver is initialized.

SRDISK is shareware. Simtel20 has it as PD1:<msdos.ramdisk>srdsk202.zip.

 Subject: New SIMTEL20 MSDOS CD-ROM, 640 megabytes, $25
 Date: 4 Jan 1993 04:54:02 GMT
 Organization: University of California, Berkeley
 Message-ID: <[e-mail]>

A new edition of the SIMTEL20 CD-ROM is available.  It contains
about 640 meg of MS-DOS shareware and public domain software.

The SIMTEL20 archive has grown since I made the last disc in September,
so there wasn't enough room to include the Ulowell games archive.  I
am planning to finish a separate games disc later this month.

Even without the games archive, there still wasn't enough room on the
disc.  I had to leave something off, so I decided to delete the
windows3 directory.  Most of the stuff in that directory is included
on the CICA disc, so I figured that was better than deleting stuff
that wasn't available elsewhere.

The disc conforms to ISO-9660, which is the most common and generic format.
It will work with almost any reader.  The files are in a standard directory
structure, so no special software is required.  An optional menu driven front
end is provided.

If you want to see what is on the disc, you can ftp the index and readme
files from cdrom.com (192.153.46.254), in the directory /pub/cdroms/simtel.
If you want to use the disc with a BBS, description files are included for
rbbs, pcboard, wildcat, spitfire and opus.  There are also 4dos descript.ion
files in each subdirectory.

The price is $25.  S&H is $5 (per order, not per disc) for US/Can/Mex, and
$10 for overseas.  If you live in California, please add sales tax.  You can
send a check or money order, or you can order with Mastercard/Visa/AmEx.

I also have these CDROMs:

I am always looking for ideas for new discs, so if there is something you
would really like to see on CD-ROM, please let me know.  In addition to
the games disc, I am also working on an Aminet disc, and a NeXT disc.
I am planning to do a TeX disc, an Atari disc and a CP/M disc in the
next few months.  I am also hoping to find time to upgrade some of the
older discs like the source disc and garbo disc.

1. What is CHEAP? There are several solutions from $50 to $150
available.

2. If I'm right informed, some TV-Cards for PC's (like ScreenMachine
from FAST for example) have TELETEXT options. (Not so cheap at all)

3. In the last year there were a project described in "'ct" (a german
magazine for computer technics). Maybe you can find something
comparable in UK/US-magazines. Material costs are approx. $ 50.

4. IMHO you can indeed make use of parts of an old TV-decoder.
Especially the decoding chip can be used from this. But if you have
good tech-docs for the TV-decoder and a little experience it should be
no problem to modify the decoder (i.e. it's interface) to match to your
RS-232-interface for the PC.

Subject: Using a Paradise 512K SVGA Board in a PS/2 Model 40SX

How can I get my PS/2 Model 40SX to recognize my Paradise 512K SVGA
board?  PS/2's have VGA on the motherboard.  Is there some utility
for disabling the built-in VGA?  Or more generally, how do you get
two SVGA boards to coexist?  Is it possible?  I have a system with
a 32-bit local bus ET4000, an Oak 1024K SVGA, and a Trident 1024k SVGA.
Each card has it's advantages and disadvantages, but I spend too much
time switching cards.

Subject: Virtual Reality

I am involved with AutoCAD and 3d Studio and have a growing interest in
multi-media, but especially virtual reality.  I mentioned this in a
chance conversation with a physician who has a practice at and teaches
at a local hospital.  He is interested in virtual reality for teaching
med students.

From this casual conversation has come a suggestion for this physician,
myself, and collegues of his to jointly investigate how he might use
this technology.

I understand that one of the cable channels in the US recently ran a
program on that very topic.  If anyone can give more info on this or
similar programs/reports I would be most interested.

Also, can anyone point me to groups or individuals who have similar
interests and would be willing to exchange information.  I would, of
course, be particularly interested in meeting/reaching persons who are
actually using/ developing this technology.

    REQUEST:

    I have a paradise accelerator card from Western Digital.

    THe drivers that came with the card apparently are old,
according to Western Digital.  When I use 1024x768 mode sometimes the
screen will freeze, sometimes the system REBOOTS sporadically (ie:
while I'm working in Windows).

    Can someone PLEASE log into their BBS (someone local to their
714 number of course or who has a 14.4 modem) and get me their newest
ACCELERATOR drivers that just came out 2 weeks ago?

    I only have a 2400 baud modem and am in Boston so it will cost
me a fortune in long distance charges...
