No.  HPFS386 is a part of LAN Server.  (It also provides some extra
features necessary for multiuser operation -- it isn't just a 32-bit
HPFS rewrite.)

Lest anyone panic, 32-bit purely for the sake of 32-bit isn't such a
hot idea.  For one, you have to spend time debugging.  (In other words,
why tamper with code that is working so well?)  For another, it isn't
all that clear that you'd get much performance boost.  (A disk -- any
disk -- is relatively slow, in computer terms.  There's usually very
little CPU involved in disk I/O, and CPU intensive operations is
precisely where you get the biggest performance boost with 32-bit
code.)

Forgive the obvious stupid question.  With OS/2 being such
multitasking, there would be several useful features found in networks
which would be useful for a stand alone system as well.  Of course I
dont know much about LAN's and such, the only multiuser OS I'm familier
with is VMS.  I'm talking about more abilities with file sharing,
especially amongst files between several tasks.  More so if it makes
programs not normally friendly for file access work more reliably in a
shared environment.

While this is true for the hardware, it still seems that 32-bit disk
interface software could still increase performance.  I'm not very
familier with the two version file system in OS/2, other than that HPFS
is very quick, and the FAT version is a lot faster than in DOS systems.
it seems that for some things HPFS is slower than a FAT system.  If it
were to go 32 bit, wouldn't the HPFS be faster all the time?

This is just idle thinking, and is probably wrong, I just don't
understand some of these things, and I'm trying to learn.

Subject: CSET/2 Problem: Using a DLL for multiple applications con



   I have compiled a language interface as a DLL using the 32-bit CSET/2
compiler. I link this DLL with a sample application. As long as I have only
one copy of this application running things work fine. But if try to run
another application (or the same application) that accesses the same DLL
while the other one is still active,
the second application gives a General Protection Fault Error. (
'Exception Occurred in C Library Routine called from EIP=----'). I am using
the INITINSTANCE and TERMINSTANCE options in my DEF file. I am linking
the C Library routines statically. If anyone has encountered similar problems
and know the solution to it or has suggestions I would like to hear from
you.

Subject: defining a timer interrupt function question

I was wondering if anybody has had any experience implementing timer
interrupt functions using Borland C++ 5.0/5.1?  Recently I attempted to
implement one for a project and was unsuccessful; Borland Tech Support
wasn't much help.

What I was able to do was implement the example timer interrupt in the
book, but that wasn't my exact implementation.  The normal stuff worked
fine - I could save the old interrupt address to a variable and set
mine, but when mine ran, the machine seemed to hang.

Certain things I have learned - you can't use 'printf' from an
interrupt function (it messes up the screen).  Is there anything else
that CAN'T be done?  (e.g., if you can't call a function from the
interrupt function, where the called function is part of the main
program, etc.)

Also, any tips for debugging such a function would be extremely
appreciated, since 'printf' is NOT an option.

If I've left out any significant details, please let me know.  I'd
really like to understand how to solve this.  By the way, probably the
best way to respond is via the net; I'm not sure that my account is
fully equipped to receive e-mail.

Thanks 10^6 in advance.

Subject: Diagnostics

I am looking for a good diagnostics program for an AT compatible.  I am
looking for something capable of determining whether or not my i486SX
has an internal cache and built in coprocessor.  I also need a true
measure of the speed of the chip as well.

I know 486 CPU's are supposed to have the built in coprocessor and
internal cache, but upon reading an article which stated only older
models of the chip contained the above, my inquiry began.

P.S.  I have tried Check-It, Norton 6.0 Sysinfo, PCTools 7.1 Sysinfo,
      ASQ by Qualitas and a few other lesser known programs.

My System         Check-It Norton 6.0 PCTools 7.1 ASQ
486 CPU               X       X          X         X
Coprocessor                                        X(Built-in)
Video Mem
(1024K)               X       X          X         X
                    256k+   256k+      1024K      256K

The above are some stats I have so far received.  My questions are very
evident.

Subject: Equivilent of UNIX exec shell cmd

PROBLEM: How do you call a batch file from a C program without leaving
the batch file "live" ?

ANSWER:  You can't.

WORK AROUND:
   1) The batch file name + path MUST be less than 16 chars

   2) Push the batch file name on the keyboard stack (requires 286 or
better).

   3) Terminate the C program

   4) The batch file on conclusion calls the C program with an argument
which places the program in the proper position.

   What happens is that the C program terminates, command.com looks for
input, the keyboard stack provides the input, the batch file is called
by the opSys, and the final action of the batch file is to recall the C
program. Perpetual motion.

        Note: (1) Some keyboard stacks may be larger than 16 chars but
you can't count on this.  (2) The chars pushed on the keyboard stack
are NOT ASCI, they must be keyboard codes

Subject: executable compression for djgpp gcc?

   Recently, I have installed the djgpp port of GNU CC on my system and
it works well. I removed the stub from the gcc executables (with
exe2aout), renamed the result to have extension .32, and defined an
executable extension .32=c:\bin\go32.exe under 4dos shell. Looks nice
and works very well.

   I have a small hard disk. For some reasons I don't want to install a
disk compression system. Most of my executables are compressed (lzexe,
pklite , diet). Obviously, the stubbed gcc executables cannot be
compressed, and I removed the stub anyway.

   What I would like to see is the following: a modified version of
go32.exe which decompresses a compressed 32bit images on the fly and,
in all other respects, does the same as go32.exe. Of course, it should
come together with a compression program. This would implement
executable file compression for the djgpp gcc port (and would save my
some megabytes of disk space...)

   Since sources are available for gcc, go32, and many compression
algorithms the task seems not so difficult (but, I'm afraid, too
difficult for me). Maybe, someone finds the idea valuable and is
willing to try it.

   Comments welcome...

Subject: Fixed point sqrt anyone?

     Here is how I do it.  This is in Microsoft C inline assembler.
This just keeps iterating till it finds the root within 1 digit.  If
you want more speed, change the '2' to something higher, but that will
decrease accuracy.  This is fast!


#include <stdio.h>

int int_sqrt( int c )
{
        _asm {
        mov     cx, 1
        mov     bx, c
        jmp     skip_iterate

iterate:
        mov     ax, cx
        sub     ax, bx   ; AX = x - y
        cwd
        xor     ax, dx
        sub     ax, dx  ; AX = abs( AX )
        cmp     ax, 2   ; 2 is the allowed error * 2, so we're getting within 1.
        jl      done    ; if abs(x-y) > 2 then goto done
skip_iterate:
        mov     ax, cx
        add     ax, bx
        shr     ax, 1
        mov     cx, ax   ; x = (x+y)/2
        cwd
        mov     ax, c
        idiv    cx
        mov     bx, ax   ; y = c / x
        jmp     iterate

done:
        mov     ax, cx
        add     ax, bx
        shr     ax, 1
        mov     c, ax
        }
        return c;
}

main()
{
        int i=32000, j, k;
        printf( "%d \n", int_sqrt( i ) );
        return 0;

486 processors and cooling:

I got a 486DX50 and the motherboard it came on had doc that said what
the performance of the board was at 66Mhz.  I read the footnotes and
they said that the 66Mhz performance figures were derived using a
"specially selected 486DX50 processor running at 66Mhz".  I said to
myself: "Self, if they have a specially selected CPU chip, maybe you
have a specially selected CPU chip?" So I turned the clock rate up to
66Mhz and it runs like a charm.  Now I am thinking if these chips are
marginal at 50Mhz, how will it be at 66Mhz?  So quick like a bunny I
run down to Fry's to see what is available.  There is a fan for a
mountain of money.  Then there is this great heat sink.

The heat sink consists of four parts:

1.  A plastic frame that grabs the corner pins of the 486 with plastic
semicircular (C shaped) clips and surrounds the chip after it is
plugged in.

2.  A heatsink which is a flat plate the size of the chip with a bunch
(200?) of teeth sticking up from it maybe 2 cm.  Anodized black Al.

3.  A wire clamp (a fancy paperclip like affair) which catches into
notches on the frame and holds the heatsink tight to the chip.

4.  Heatsink compound.

Installation instructions:

1. Remove 486 from socket.   (This is the hardest and most dangerous step)
2. Place frame on the legs of the chip, and reinsert chip in socket.
3. Apply about .1cc heatsink compound to the flat side of the heat sink.
4. Set the heatsink on the 486.
5. Install the clamp so as to hold the heatsink firmly up against the chip.

That's it.  The heatsink is about $4, the frame and clamp is about
$1.50, the heatsink compound is about $7 for enough to service all the
486 chips in Europe.  The $7 tube is probably enough for 50 chips.

THE TIME TO INSTALL THIS PUPPY IS WHEN YOU ARE CHANGING CPUs OR
INSTALLING A CPU IN A BARE BOARD.  BUY AT LEAST THE FRAME NOW (FOR
$1.50).  THEN YOU WILL HAVE IT THE DAY YOU NEED TO PULL THE CHIP
ANYWAY.

It seems to reduce the chip temp from too-hot-to-touch to hot.  That is
surely worth it.   Good luck.  If you need actual part numbers, I will
try to get them.   Dave

Subject: In Dire Straights With Excel...

Help! Help! Help!

I am writing an application using Excel's macro language. The program
periodically updates graphs, using data obtained from a database that
runs on a VAX/VMS system.

I are a couple of items in my user interface that I haven't been able
to figure out how to implement using the functions available in Excel.
I've called Microsoft's tech support on 2 different occasions, with 2
different problems, but wasn't able to get the help I needed.

The folks I talked to at Microsoft were nice enough, and they did try
to help, but my questions were apparently outside the scope of what the
help desk can answer. They recommended that I check their product
support forum on Compuserve. Their programmers are available on there
to answer questions.

That sounds great, but I don't have access to Compuserve, and as far as
I'm concerned, their rates are outrageous. What I was hoping is that I
would be able to reach someone on the Excel development team from the
Internet. I know that Microsoft has an Internet link, so it must be
possible. I don't know how to reach anyone there, though.

I would be very greatful if someone out there could provide me with an
e-mail address for someone at Microsoft, or a way to reach them on
Compuserve (via the Internet, I mean). If there is actually someone
from Microsoft reading this it would be perfect!

Subject: PKZIP 2.04c for MS-DOS (!) uploaded

I have uploaded to ftp-os2.nmsu.edu:/pub/uploads/pkz204c.exe the new
version of PKZIP/PKUNZIP, released on 5 Jan 93.  Here's my description
file:

Program Description [ PKZ204C.EXE:  PKZIP v2.04c for *MS-DOS* ]

Program Source: (PKWARE BBS -> wuarchive -> trusted ftp site -> Greg
Roelofs) Proposed directory: os2/all/archivers/

Notes:  See comp.compression for loads of discussion about this file.

  This executable is the version which was tested by Vesselin Bontchev
of the German anti-virus institute (whatever it's called); it *is*
virus-free, as he has publicly attested, despite the reports of old
versions of Norton Anti-Virus (2.0 or earlier, which falsely report the
presence of the Maltese Amoeba virus).

  The proper size for this file is 188818 bytes; Unix "sum pkz204c.exe"
reports "36332 185".  Zipping it into another zipfile (e.g., with
"zip19 test pkz204c.exe") gives a CRC of d864b4ba.

  NOTE THAT THIS IS AN MS-DOS PROGRAM!!  I uploaded it because a lot of
folks seem to prefer official PKWARE products over Info-ZIP's UnZip
(Philistines!! :-b ).  This version of PKUNZIP will extract zipfiles
created by Zip 1.9 (to the best of our knowledge), but it will NOT
restore any OS/2 extended attributes which have been saved (obviously--
this is an MS-DOS program, after all).  Ya gets what ya asks for...

  Note also that several bugs have already been reported, including
ones with the auto-detection and use of DPMI memory.  Therefore, use
the -) switch when running under OS/2 2.0, at least (and maybe when
running under 1.x, too).  Someone posted more detailed hints in
comp.compression.

  Finally, note that this version of PKZIP can create files which UnZip
5.0 is unable to extract--in particular, the file PKZIP.EXE itself is
not extractable.  A "semi-official" patch to the sources has already
been posted to comp.compression by Mark Adler (author of the inflate
routine); look for a more official patch plus new executables, etc., to
be available sometime next week (10-16 Jan 93), with luck.  This patch
release will NOT in all likelihood handle multi-part archives.

What do I need to do to connect a Prime CDC MFM 515Meg Hard drive to a
IBM compatable?   What kind of card and driver?

Thanks in advance for your help

Just as you always did in Windows, really.  Double click on the
Win-OS/2 Full Screen object in your Command Prompts folder.  Then, from
Program Manager, select File -> New (Program Item) and click OK.
Proceed from there.

Take a look at xfeel.zip, available via anonymous ftp from
ftp-os2.nmsu.edu.  Check the file /pub/os2/00Index for location.

Hold down SHIFT while positioning the window -- this will preserve its
location for the next time you open it.

>  As a side question, is there a way of preventing that question
>requestor from appearing when I close a shell?

Yes.  Use the EXIT command to exit the shell.  This shuts down the
shell safely, and does not provide that warning dialog.

>Is there any bad side effect, beside of the possibility that the data
>will not be saved?

No, no bad side effect, but the operating system really has no way of
knowing that you haven't saved your work in such a session.  Hence, it
presents the warning, to make sure you know what you're doing.  Using
the EXIT command bypasses this dialog, because it does perform a
"known" means of exit.

>4) Are there any good books that  are of the more advanced nature,
>that explain what certain files do,  the layout of OS/2, etc.

The IBM OS/2 Redbooks are very helpful.  You can obtain them in
electronic form via anonymous ftp from software.watson.ibm.com, then
print them out.  Or you can order the set for about $25 in printed
form; see the FAQ List for details.  There are other third party books
which do a nice job -- just check your local computer book store and
find one you like.

>5)   What exactly do the config.sys and autoexec.bat file do?  From

Can you rephrase the question?  I'm not sure what you're asking here.
I followed you until the last sentence, and you were correct up to that
point, as far as I can tell.

>6)  How do delete an icon for a program without deleteing the program?

Run, do not walk, to ftp-os2.nmsu.edu and get ahold of the Unofficial
Guide to the Workplace Shell.  Read it, and all will be clear.  :-)

Correct.

Check that ftp-os2.nmsu.edu -- you'll be pleasantly surprised.

Subject: Trap D error (OS/2 2.1 beta)

I found the same solution (i.e. unsetting the DELDIR environment
variable) for TRAP D's. They occured after installation of 2.1 Beta
over my GA+SP system as soon more than two files where deleted (two
'del x.y' cmds in a row resulted in a TRAP D as well as a 'del *.*', no
matter if OS/2 or DOS session).

The system was almost useless at that point. Running TCP/IP and having
SENDMAIL receiving files generated a TRAP D almost every minute.

Previously I had installed the 2.1 Beta in it's own partition and since
it worked quite nicely, I decided to install it over my "production"
system (after a backup, of course). But now I migrated the
config.sys/autoexec.bat files of the existing GA+SP which had 'SET
DELDIR...' lines. Funny, why are these lines always REMed out after new
installations of OS/2 ?? When I unREMed the lines in the separate
installation of the 2.1 beta the TRAP D showed up as well.

Removing the 'SET DELDIR....' lines from config.sys and autoexec.bat
made my day and the 2.1 beta runs flawlessly now (esp. Win 3.1 Enhanced
mode, I love it :-)) with my previous desktop !!!

Subject: Unexpected DOS Error 5 ?????

While I was home over Christmas, I happened to start talking to a
friend about PC's. It turns out he had just purchased a 486DX2/66 and
was running OS/2 with dual-boot. After I quit drooling, I started
helping him configure it to run at its best.

During this process, we ran into a couple of problems I couldn't solve.

1) He was running an ATI Ultra Plus (I think that's what it was
called). OS/2 put it into 8514/A mode at VGA resolution by default, and
he's unhappy with the refresh rate and the resolution.

My best answer for him, especially after reading a few of the threads
around this group the past few days, is to live with it until OS/2 2.1,
which should have ATI drivers. Any other suggestions?

2) The much more serious problem was an error message when we tried to
start up a bunch of migrated DOS apps. He kept getting the error
message mentioned in the Subject for this post. I've seen this before,
but I can't remember how I fixed it. I suggested that he just reinstall
most of these apps under OS/2, but I promised to check this out before
he did that. Any help for him?

Any help anyone can give would go a long way to completing my friend's
commitment to OS/2 over DOS/MS-Windows, which would be a Good Thing :)

Subject: What program should I use to see my computer's speed?

The subject says it all.
I want something which I can run with/without turbo and it will say
clearly X MhZ. Of course,public domain or shareware is preferable.

Thank you
