assistant: Hi..
088kb-16
o
I take it by the phrade '16-bit pointer' that what you mean to say is the
seg:ofs addressing mode. Alhough the 'ofs' has a limit of 64kb in real mode,
it's not really relevant. do the math I mentioned originally. Segment FFFF,
offset 4096, for example:
   FFFF0    (seg)
+   4096    (ofs)
= 104086    (Resultant address)
Clearly this is BEYOND the first megabyte. Try it some time. It works. It's
how himem.sys 'creates' and accesses the HMA, which is beyond 1Mb, without
entering protected mode. The only thing himem does is to enable A20 so that
the addresses don't wrap - but that's an artifact of the IBM-PC Design, NOT
an artifact of the 80286, which is what we are discussing...
Ray is wrong, or rather I'd say he is the victim of making an oversimplistic
statement- at first it reads correctly, and indeed it is the truth for an
8088/ 8086/80188/80186... and even the 'default' hardware design of the 286
based PC..
It is still NOT true for the 80286 ITSELF!!!

masm can generate COFF object files, which is the .o standard

assistant: [Startup segment values of a .COM program under DOS]
[David]
[... Discussion deleted ...]
Under TD v3.2 (Turbo Debugger from Borland), _all_ Registers are initialized
to 0 except for the segment registers. I would not conclude from behaviour of
certain debuggers to behaviour of DOS (and its various emulations).
According to Ralf Brown, a .COM file starts with the following values in the
registers :
        .COM-format executables begin running with the following register
          values:
                AL = 00h if first FCB has valid drive letter, FFh if not
                AH = 00h if second FCB has valid drive letter, FFh if not
                CS,DS,ES,SS = PSP segment
                SP = offset of last word available in first 64K segment
                (note: AX is always 0000h under DESQview)
This does obviously not contradict your findings assuming that you didn't
start your programs with a command line (and not under DesqView).
There is a program in the snippets that dumps all register values at startup
time. Assumptions on the values of certain registers are IMO only interesting
when optimizing for _size_ and a total file size <= 4KB, that is in most of
the time smaller than the smallest sector size of a HD these days (NTFS and
VFAT32 can have 4K sectors AFAIK) and thus futile ;-).

I've never heard of a program to do this.  It'd also be considerably

Assembly language would be the best area, looking at programming as 'the
philosopy/physics of math, or even the math of philosophy/physics'.  You
know, the hard-core stuff, like fractal compression, a-life, nueral
nets, ect.  The stuff that questions the true identity of 'order' as we

Something just crossed my mind.. I dunno if this would work, i'm no rendering
genius..  but couldn't you just draw the whole thing sequentially ?  scanline
by scanline ?  like, traverse each pixel looking for the nearest polygon that
should be drawn there, clip & draw that poly, then keep going, skipping the
pixels that have already been rendered.  You just have to check for
overlapping polys or else your drawing order will be kaput.  You'd be doing
the thing in reverse kinda.. instead of going from polygon to pixel, you'd
find the polygons FROM the pixels.  Just a random idea..
