Subject: "Crazy" question about EGA and CGA? Help!

   I have one "crazy" question for the Net. I heard about TSR programs
(screen drivers) which allow to emulate CGA (Color Graphic Adaptor) on
Hercules Graphic Card (of course, B&W version). I do not know does this
emulator reproduce all properties of CGA or not. It is easy to check
but it does not matter. I can belive that a Clever Programmer could
write such nice thing perfectly. Ok ...

   The question is - Have ANYBODY SEEN or HEARD about the program
(programs) which allows to emulate EGA (Enhanced Graphic Adaptor) (all
or some graphic modes) on CGA (Color Graphic Adaptor)? (Surely, I know
about 4 colors on CGA and 16 colors (from 64) on EGA, and different
mode resolutions, and other differences between the cards, etc ...) And
nevertheless ...!? Maybe somebody knows where I could get such program
(if it exists).

   I have some experience in programming but I can not imagine how one
could implement this program(s). The question is of great both
theoretical and practical interests.

   I would be glad to get any information about such program(s).
Thanks in advance,

                                                     Maksim Stolyarov

Subject: 800x600 on display HOW?

        I have installed the 2.1b and everything seems to work fine.
BUT! I have set the display type to SVGA during install yet it looks
like it is still displaying 600x480 (VGA?).  I have an HP Ultra VGA
card with an HP Super VGA monitor.  I have windows 3.1 set up for
800x600 and it works fine.  So what do I need to do to get the higher
res. on my display?

Thanks

Subject: 800x600 on display HOW?

[e-mail] (David Slack) writes about OS/2 2.1 Beta apparently
not installing SVGA and wonders how to fix this...

Look in "OS/2 System" -> "System Setup" -> "System" -> "Screen"

This will show you a notebook with the settings available to you with
the currently selected one highlit.  Or if you're running VGA mode, the
first one is highlit.  If you only have VGA then the "Screen" page of
the notebook won't be shown.

Have fun,

Yep, this will definitely blow things up nicely...

Although you can use 386-style 32-bit effective addresses in real mode
(by specifying the appropriate instruction prefix of 0x67), they are
still limited to a maximum value of (64KB - 1).  This is because the
segment limit cached into each and every segment register is (64KB - 1)
when in real mode.  It would be impossible to change these limits
without switching to protected mode and reloading the segment register,
and would have unpredictable results back in real mode.  If you do
exceed a segment limit in real mode, it will generate an exception,
which will hang most machines because the real-mode BIOS usually cannot
distinguish an exception specific to a 286 or higher processor from a
hardware/software interrupt, and doesn't know how to recover.  So
basically, you *can't* do the above!

But there is a tricky way to get a little less than 64KB of additional
memory in real mode, which is the basis for the HMA (High Memory Area)
specification.  It is possible, even with 16-bit offset and segment
values in real mode, to create an address greater than 1MB.  Consider
the far address 0xFFFF:0xFFFF.  The corresponding linear address would
be 0x10FFEF, clearly above 1MB.  The 386, like the 286, will not wrap
this address around to 0xFFEF the way the 8086/88/186 does, given the
larger address bus.  And this address doesn't violate segment limits
set for real mode.

There are a few gotchas with using the HMA.  For one, most
PC-compatible systems by default deliberately disable address lines A20
(and above?) to protect 8086 software (sometimes including the BIOS
itself) which *expect* wraparound to occur past 1MB.  Before using the
HMA, you must enable A20, and the method varies from system to system.
True AT-compatibles, PS/2's, HP Vectras, and AT&T 6300's all use
different methods, some of them truly bizarre, in order to really
protect this line from casually being changed.  On an AT-compatible,
the A20 gate is enabled using the 8042 keyboard controller, of all
things!

Another has to do with normalization of far pointers.  To normalize
means to set up the segment and offset so that there are no overlapping
set bits between them, and is handy for "uniqueifying" an address.  The
problem with this is that it breaks the HMA, since you can't go above
1MB with a normalized address!  So be wary of DOS functions which might
want to normalize your pointer first.

Good luck!

Voila, I think the following lines in C (to be exact C-Preprocessor)
show the abilities quite well. I think the macros are described by
their names, so no further comments are needed. BTW: There are much
more features available. They are described in the documentation to

Hi all,
the question might not be related directly, but as some of us use
graphics- programs, I thought to give it a try: For example Corel Draw
or Photopaint use CMYK colordefinitions.

C is for Cyan
M is for Magenta
Y is for Yellow
K is for ???

(I know it is black) BUT WHY THE HECK K and not B ????!!!!!  I've
already read about 8 books on this issue, none could answer my
question.

Any ideas?

Subject: Fdisk and partitions question

        If there is someone out there who knows EXACTLY what fdisk does
I'd like some help on the following problem:

        Recently my system lost the primary partition information
somehow, my primary partition shows up as a Non-Dos one.  My question
is will fdisk destroy the information on that partition if I delete it
and set it back up as primary dos of exactly the same size?  I'm hoping
if I do this and not format the partition the system may be able to
boot again provided other information was not destroyed.

        To sum up I'd like to restate the partition information, but
not format, and recover that partition's data.

Here is the story on ISO 9660:

First there was High Sierra, a CD-ROM file structure format
specification developed by a group of CD-ROM industry representatives.
It was used on the majority of CD-ROMs produced between 1986 - 1988.

ISO 9660 is a CD-ROM file structure format standard based on the High
Sierra specification.  It was approved late in 87 and gained support
and became used in 88.  It is very similar to HS, but ISO 9660 sheds
the MS-DOS restrictions.  It is THE official standard now.

I stay away from Sony CD-ROM drives.  Sony has its own world of
weirdness, which I believe is either designed to confuse consumers so
they will be afraid to buy anything that is not Sony, or else they are
kidding themselves that the universe revolves around Sony.  Nobody else
uses "mode 1 & 2." Looking at a catalog though I would bet $$ that Mode
1 is High Sierra, and Mode 2 is ISO 9660.  The catalog makes a big deal
out of being compatible with the CD-ROM XA standard.  It is a
"standard" written by Sony.

Don't worry.  There is nobody today who would make data disks or drives
that don't conform to the ISO 9660.  No one would buy them.

Hum, I know the 1703S, 1700S, and the 1750S but not the 1705S.  Anyway,
the device driver should have been with the drive.  You will have to
get one from Hitachi or a Hitachi dealer.  I can only turn you on to
some U.S. dealers.  Basically, the bulk of the Hitachi serial drives
just have two drivers; hitachia.sys (regular) and hitachib.sys (mca),
in case you run across one somewhere.  (1750S is SCSI)

Also, in order to use the CD-ROM drive you will need to buy Microsoft
CD-ROM Extensions.  The MSCDEX software will have good instructions
included, but basically, you load the driver in the config.sys and the
MSCDEX in the autoexec.bat.  Be sure you give the device the same name
in both places.  If you have problems, after you get the device driver
and the MSCDEX, send me some e-mail.

The reason that you lose memory is, the PRINT.COM is a Terminate and
Stay Resident program (TSR).  When you do "system (...)", the code runs
a new COMMAND.COM and passes the string as a command for it to run.
Since it is a TSR it will install itself in memory and when your C
program ends, it can't release the memory it has as the TSR has
"locked" it.

Solution, run all TSR's like PRINT from the AUTOEXEC.BAT or don't use
them.  Try, system ("copy jnk.c prn");  It will not be as fast as it
has to wait for the print to complete, but it is safe.

Second solution, check to see if PRINT is already in memory.  I do not
have the doco but I understand thet interrupt 28H can be used to see if
PRINT is loaded.

How?  Unless you get the USENET newsgroups, you CAN'T get Comp.os.os2.misc...
If you *do* get the newsgroups, tell your newsreader software
"g comp.os.os2.misc" and you're signed up.

How to get to FTP-OS2.nmsu.edu (aka HOBBES.nmsu.edu) and

Subject: PS/2 Tape Drive.

Hello There,

  I have an internal tape backup unit on my PS/2 Mod. 80, and it
occupies floppy drive slot B. Has any one used any version of tar under
DOS with it ?

  Is it possible to configure it through DRIVER.SYS and DRIVPARM as a
logical drive so that tar could be used with it ? if so how ?

Thanks,

A.Ibrahim,
Uni. Of Manchester, UK.

PS : If Mr. W.Flusek of the USA is reading this, pleas contact me.

Subject: SETCLOCK & GETCLOCK utilities for the XT

I have this ancient XT with a Real Time Clock and floppy controller on
a card.  In order to read from the Real Time Clock or set the RTC, you
need the two utilities SETCLOCK and GETCLOCK which I have lost.  Can
someone tell me where I can get a copy of these two utilities?  Or tell
me the address of the RTC so that I can write one?

Just in case you are wondering, I do have a 386.  The XT is just for me
to play around.
