This is a good head-scratcher. Are the changes "real" ... do they recur in
the same place on viewing the same file and with different apps, do they
print fine, etc? If not, I'd suspect video driver; if so, I'd suspect drive

It is up to the individual application to either use a system font or save
its own font settings. If it uses a standard system listbox, for example,
it will get the saved system listbox font. But if the author changes the
fonts, then they are responsible for saving them (preferably in their *own*
INI file, instead of the system INI file). Bitch to the individual program
authors about this one. Now, there is one place you'll see something like
this in WPS -- if you set the font/color of a folder, for example, then
later change the system font/color (using Alt-drag), this folder will *not*
assume the new setting. To have this folder get the (new) system setting,
you have to set it to "Default" in the settings notebook.

P.S. -- I'd recommend reorganizing your CONFIG.SYS; it's a mess. :-)

Hello and Greetings,

A very good friend, and computer wiz in his own right, highly recommended
that I join this "LIST" and seek your highly esteemed assistance. I am a
real novice to date, but nevertheless very glad to have started the journey.
However, I have found myself in a dilema. Please allow me to explain.

First, let me give you the pertinent data on my pc. It is a 386 IBM PS/1.
I am running DOS 6.2, and WINDOWS 3.1. Also a mouse and a vga monitor. It
has a total of 80+ MB, 16+ clear. It is running extended memory with

The problem started with the system "locking up" on a program running in
windows. After ten minutes, or so, I impatiently turned the computer off.
That was the last time I saw WINDOWS. Now when the pc is turned on I get
the notice "Could not find or open ANSI.KEY". This also comes on when I
move to the TELIX.EXE in opening my internet account. I have looked and
found the ANSI.KEY file in both TELIX and DOS. The directional arrows on
my keyboard are also malfunctioning. Dos is working well enough, thank
God, to make this request for help and handle e-mail. I am sure it can do
much more than this, but I am a WINDOWS user, and not familiar with DOS.

This list has a good reputation for being helpful to others in need
(ie. friendly). I could sure use some helpful advice about now. Hope
someone is interested! Thanks!

Subject: False "Hard disk controller error"

That's the problem, folks, but read on to see how bizzare PCs can be.

I have two old boards, a 286 and a 386sx. They have one thing in common
-- they've been on the shelf so long their on-board batteries are
totally dead and won't hold a charge.

They have a second trait in common. On bootup,if the battery is dead
they say the CMOS is bad and want me to fill it in then, if I exit,
they will access the hard disk. BUT, if I reboot with a (partially?)
charged battery I get "Hard disk controller error." Yes, I get
this sequence placing either hard disk on either MoBo.

I have tried using 3+v and 6v external batteries on the 386, which
produces an immediate HD error message and no further progress.

If I unplug the hard disk controller then the machine boots normally.

So I don't have bad hard disk controllers, I have CMOS that
thinks they are bad, but only if the CMOS battery keeps it alive.

This is beyond me.

Do you have any advice or ideas? Please send direct to me or post

serious trouble getting sound from game programs to work properly.
Various game programs that supposedly work with "100% Soundblaster

Subject: problems with Ontrack DM ?

I will appreciate if any of you can help me with the following

1) I have installed a WD AC-2850-00F Caviar disk in my system, in
addition to the existing Seagate ST3250A drive. Both drives are
connected to the same IDE card, and I have configured the
Seagate as the Master, and the WD as the slave. I am using Ontrack
Disk Manager to get access to the WD full capacity, and the DMCFIG to

get 32-bit disk access in Windows (3.11). I have partitioned the WD
drive into 4 partitions of the following sizes: 255MB, 255MB, 255MB,
80MB. I made the necessary changes in "386 Enhanced" in Control
and marked both File access and Disk access as 32-bit access.

After restarting windows, I get 32-bit File access only on drive C:
(the original Seagate), while all the WD partitions (D:, E:, F:, G:)
are marked as 16-bit FIle access (Disk access is 32-bit). Windows
3.11 documentation says that this means that those partitions can't
accessed by 32 bit file access, while the disk documentation says it
should be able to handle 32-bit file access.

How can I change File access to be 32-bit?

2) I noticed that some software products can't operate if installed
on any of the WD partitions. Such products are: VIBRA16
(Sound-Blaster 16 software) and Goblins-3. Is this because of some
incompatibility with the Ontrack DM ?

What's different in this case from any other file-oriented program? I
usually set smartdrv to write-back operation (/N) on any hard disk and
write-through on floppies. I never had any problems with that setting.

If what bothers you is the possibility of losing characters which come
through COM ports when smartdrv decides it's time to flush the cache, then
the solution isn't some switch to smartdrv but something which will drop
the RTS line when this happens. I have a TSR somewhere which does just
that, called RTS14.ZIP, which you could probably find with archie (or I
can mail it to you if you can't).

> In fact, can anybody explain what different settings are best for
> different kinds of computer work and why?

I have found that delayed write operation should be preferred for any
work except in two cases:

1) When your program writes huge amounts of data that will always
overflow the cache many times.

2) When you program hooks hardware interrupts that need to be
serviced ASAP.

In both of the above cases I recommend turning delayed-write feature OFF,
or even disabling the cache altogether.

a) Do not try to run DOS networking products under OS/2. You are only
asking for trouble. It can be done in some circumstances (e.g., there used
to be a lot of info about running Lantastic for DOS before Lantastic for
OS/2 was released) but universally you are better using OS/2 for networking.
If you're going to bother with using such a better OS, why not use those
features it excels at particularly well?

b) There is a faq on this on the ftp site The file is, and I think it is in /os2/network.

c) OS/2 Peer that comes with Warp Connect works fine with WFW LANs; it is a
complete NETBIOS LAN system. This is by far the best solution. There is
documentation in the box for using Peer with WFW. I use Lan Server (threw
out WFW years ago ... good riddance!), so please don't ask me for further
info on WFW<->Peer, but I've read the manual and I've seen it work. It
seems pretty much a no-brainer, though you do have to know the name of all
your LAN resources beforehand.

Well, First I think it must be EIDE drive because IDE parameters
end at 1024 Cyls, 16 Heads and 63 Sectors. Maybe IBM cannot call
their disks EIDE because it is a standard invented by Western Digital.
And for example Seagate calls its disks Fast ATA.
Then I think you have three solutions:

1. Buy a motherboard which supports LBA.
2. Buy an EIDE disk controller which can 'see' your large disk using
his own driver (installed in CONFIG.SYS).
3. Try to use a program called OnTrack Manager which comes with
Western Digital disks and seems to work with every hard disk.

I tried IRQ 10 (even though MS-diagnostic said 10 was reserved. I also
tried 2, 5, and 7. MSD says 2 is my second 8259A, 5 is LPT2, and 7 is
LPT1. I tried them all anyway and still got the messed up sound on some
wav files. The only time it worked ok was when I took the card with the
second parallel port out. I even tried changing both parallel ports to
IRQ 5 and then tried all the IRQs I could for the sound card and it still
didn't work. Also, MSD said that the LPT ports still had the 5 and 7 IRQ
when I changed them to both 5. Is that just MS Diagnostics messing up or
can you not change the IRQ for the parallel ports even if you have
jumpers to do so?

It seems like I might need to get a switch box for my parallel port 1 and
just plug the printer and snappy into that. I tried that before with a
manual switch but sometimes it didn't work right. What about the
electronic ones that doesn't have a switch to flip? Would they work??

Don't use 2. The 8259A is your interrupt controller.

MSD only GUESSES at IRQ 5 and 7 since it cannot be sure
without trying the port.

For your information, Windows and DOS usually do NOT use
IRQs to control parallel ports. OS/2 and/or print queue
programs might, but that depends. Not sure about WfW.

Here's the "usual" IRQ assignments:

0 DOS Timer (do not use)
1 Keyboard (do not use)
2 Cascade Interrupt / 2nd 8259A (do not use)
3 COM2/4
4 COM1/3
5 LPT2
6 Floppy (do not use)
7 LPT1

The higher IRQs are not listed because some games do not
work with IRQs above 7.

Of the 8 interrupts, only four are available. And if you
have four different ports, then you don't have a free
IRQ. Ports usually cannot share IRQs without special
hardware, but there are exceptions, see below.

From your description, it sounds as if you have both
LPT1 and LPT2. As explained before, LPT ports under DOS
and Windows use "polling" technique, and does not use
IRQs. So it is usually okay to use IRQ5 for your
soundcard, UNLESS you run into problems.

Should you run into problems, it may be possible to set
your parallel port to use a different interrupt. That
depends on your I/O card.

Subject: /Tm option weirdness in Visual Age C++

Recently I issued a request for help for a program that was aborting
before even reaching main. I managed to make the problem go away,
but I don't know whether I've really addressed its cause or just
removed a symptom.

I'm using Visual Age C++ with the most recent fixes.

The executable used a home grown DLL. The DLL's object files were
compiled using /Tm, but the executable's were not. When I added the
/Tm option to their compile, the problem disappeared.

Then we asked ourselves what would happen if the situation were
reversed, if the DLL was compiled without the /Tm, but the EXE was
compiled with it. We tried it, and the program aborted before

I can't believe that this would be a general rule, as it is not
reasonable to expect that third party DLL's be compiled with /Tm.

So, this problem must be masking another problem. That is, there's
probably some error in our code that's causing this to happen.

Any thoughts on this? Thanks much.

Subject: Re: /Tm option weirdness in Visual Age C++

Hello, Keith!

When you use the /Tm option with VA C++, you are actually replacing
some of the memory management modules. The new modules will add
some data to the beginning and end of each block of memory you allocate,
where they will store such information as the original size of the memory
block, the address in your program from which it was allocated, and some
additional information (such as checksums and data patterns to detect if
you overwrite memory immediately before or immediately after this
memory block's boundaries). The memory address returned to your own
program is the address at which your data block actually starts; that is,
the added header and trailer is "invisible" to your program.

So, a program compiled with /Tm+ is fundamentally incompatible with a
DLL compiled with /Tm- (and vice-versa). For example, if you call free()
from a program compiled with /Tm+, the function will "back up" from the
address you passed, to find the added header, and will add the length of
that added header plus the trailer, and delete THAT block of memory.
Obviously, if you are calling a DLL that allocated that block of memory
via the "normal" memory management functions, there IS no header or
footer for the memory block -- a recipe for trouble!

Hope this helps!

The only differences I can think of would be quality of the moulding,

Not sure, haven't used them personally. Maybe the same as serial cables?

Null-modem cables, or "laplink" cables have the transmit and receive
lines crossed, so they're generally used for file transfer or multiplayer
games. Plain, "straight-through" cables are generally used to extend modem
cables for connections to the serial port.

Null-modem is serial, since the crossed TX and RX lines simulate modem
communications (without the modems). I think "cross-over" cables are the
same as null-modem; straight-through cables are just modem cable extenders.

Your cable can probably be used to extend either one - all it does is
connect 25 pins on one to 25 pins on the other. You'll probably need a
gender changer to use it for serial, since the "M/M" means male-to-male
sockets, and serial cables need female ends.
