I may be wrong, but that was not true for the earlier 80x86's.

     I did :-)
     ...(fade.asm that you posted)...
     You implied that this bat will restore the screen?
     This did not restore the screen after running the fade.
     I added some code to detect a keypress, clear it, and
     invoke a mode3 screen. Then your batch would set 43 lines.
     Also removed all the delay loops!
     They did nothing, here (ET-4000 isa vga card).
     I would rather fade up the screen.
     Here is the A86 format code.

Wow! I had no idea the buffer was this big. It took hours for me to find

192 color registers * 64 something registers.

assistant: Yo All,
I've setup a 640x480x256 VESA mode with a lineair framebuffer.
VBE2 tells me that I can find the lfb at location 30000000h.
I tried to write something to it, I tried several methods :
1.    GS:30000000h (in PMODE with GS pointing to absolute 0000)
2.    3000:0000    (seeing it as a realmode address)
3.    30000000h - start32 (start32 points to begin of my prog)
4.    30000000h + start32 (it won't hurt to try, desperate as I am...)
5.    ...
...
but my computer always crashes or resets, so I think it's because I'm
writing to a location for which I don't have access rights.
How do I make such a structure (in GDT,...) to give me those rights ?
I'm using PMODE v2.1232 by Tran of Renaissance.
My video card is an S3TrioV64+ (for the lfb).
Have a nice day, All!

That's exactly the code the original poster had that does _not_ work!
It will NOT change the number of lines on the screen.
And worse yet, it won't leave you with 50 lines unless you were already
using 50 lines...
That's true.  Unless you 1) know the exact model of card in use, or 2)
at least know that the card supports VESA extensions, you can't do much
with 132 column modes.
I don't think it's too useful.  You really have three choices: 1) stick
to VGA modes, in which case you ignore the possibility of 132 columns at
all.  2) Use VESA modes, in which case you simply change `3' to the
appropriate number (I don't have all the VESA numbers memorized...) or
3) write to a specific card and/or simply allow the user to enter a mode
number of their choice.
I was assuming the first option, sticking to VGA modes.
    Later,
    Jerry.

Re: DJGPP, gcc et al following:
Although I'm not Paul, I answer you anyway:
DJGPP - DJ GNU Programming Platform, is a DOS Port of GNU's C&C++
Compilers and some other GNU Tools like GAS (GNU Assembler), the GNU
Debuggers and the whole binary tools a.s.o. The code quality of djgpp is
on the level of the well known C/C++ Compilers like Watcom and Borland.
There are also a lot of tools which make a real good development
environment out of djgpp. But the best thing is that you can use djgpp for
free, even for your comercial projects. There are also some disadvantages
in using djgpp. One can only develope DOS programs. One have to use the
AT&T Syntax while writing ASM Code. And the original djgpp distribution
can only produce 386- and 486-optimized code, but there are a pentium
optimized package out which was developed by the Pentium Optimization
Group. If you're interested in more information about GNU just visit
www.delorie.com, the home of djgpp.

That prefix is the operand-size prefix, which is required for most
instructions that use 32-bit register/memory operands (in a Use16 segment...
a Use32 segment would need the byte to do 16-bit reg/mem operands)... however
I don't know how to get rid of it, since I don't know why your compiler is
adding it...  I think GCC is probably making a Use32 segment, so that the
instructions for 32-bit operands don't need the prefix.

 Encyclopedia (PCGPE10.ZIP) which has some SVGA stuff in it.
 Using them? How do you mean? To set the modes, just use them like you would
 for a BIOS VIDEO change mode call. Then to plot pixels, you could try using
 the BIOS' own pixel plotting function which should support the card you
 have.
 BTW: Make sure you have the VESA driver loaded before hand or something
      similar to connect the VESA specs with your card.

 DEBUG in OpenDOS! It also supports 386+ instructions and even Pentium
 instructions and everything else in between!
 The only downside is you can't actually see the registers in the R listing,
 only the standard 808x ones. However you can assemble and dis-assemble the
 code and even modify the registers with R.
 ie:
 A
 mov    EAX,ABCD1234
 R EAX
 EAX ABCD1234

 Since OpenDOS is really Novell DOS, I imagine Novell DOS / DR-DOS has the
 same capabilities.

Write your reply.

assistant: Yep, it's a 386+ prefix that would allow DWORD sized chunks of memory to
 be moved instead of WORD sized. (Possibly other things as well)
 ie:
    REP MOVSD       ;mov a DWORD chunk on a 386
Could be done as:
    db  66h         ;386 prefix
    REP MOVSW       ;to 8x code to move a DWORD chunk
 DJGPP Is a 386 C compiler isn't it? As such I doubt you'll be able to get
 rid of it. Unless you can over-ride 386 code generation and use 808x code
 generation instead.
