The method it used is the more standard, and (in most cases) more accepted
method of transferring values between segment registers...  Obviously A86 had
not expected the stack to be invalid at that point... Perhaps you could find
way to disable "SMART" code generation (which is what tried to help you out

fixing your mov ss, cs), and then you can use your own methods to make SURE
t
does it the right way.

Write your reply.

assistant: Bonjour All !
    Can someone help me understand how works the CPU generated interrupts 06
& 07 (INVALID OPCODE & NO PROCESSOR EXTENSION AVAILIBLE), I heard that it is
possible to emulate other instructions/processor using those interrupts, for
example, when reprogramming int 06, it is possible, for example, to emulate
pentium instructions on a 486, or even MMX instructions on a pentium
processor. The int 07 can be used to emulate a math coprocessor when it is
not present...
    Any information or even book reference would be great.
Amiti�s,
David.

Right! it seems to be that but could you say more ... i don't know how make
this :(
Maybe you could Netmail me in priviate @2:293/3407.24. I Think that was beter
for the other who know already all of this little stuff !
To launch the chat, I want to say : how can I execute an ARJ-DOS call in a
window like that without kill that window =>
        ...
        window(2,10,78,18);        {This windows must'n NEVER modifyed}

        exec('arj.exe','-x file.arj');      {But this call kill it :( }
        swapvectors;
        ...
So I must hook the display, ok but if you have an idea on how make this I'm
listening attentively :))

Write your reply.

assistant: You still need to restore DS!  This part might not need it, but much of the
rest of your program will probably need to know where the data segment is...
If you're doing this in protected mode, you'd probably get a GPF the next
ime
you tried to access something in the data segment.  There are three ways that
the DS register can be restored:
1. The way I showed above, which make your assembler add a reference in the
appropriate FIXUPP record so that the place in your code where you specified
it will be replaced at runtime by the appropriate value for DS.
2. Declare another code segment variable, SaveDS, and do the save & restore
y
your method.
3. You can PUSH DS, then save the stack... when the stack is restored, you
an
pop DS...  You could also do similarly for BP... and if you're calling this
from a C program, you might want to preserve SI and DI also.

Write your reply.

assistant: Look for docs on VESA BIOS Extensions (VBE 2.0) ... you can set
640x480x24bpp mode with an int 10h call, only being a VESA mode the arguments
are slightly different to the standard BIOS set mode call. The most annoying
thing about hi res modes like this is that you can't just plonk a value into
memory for every pixel on screen like in MCGA mode. 640x480x3 (3 bytes per
pixel) is well and truly over the 64k segment size limit, so you'll need
additional int 10h calls to bank switch (ie, tell the video card which
section of the screen the memory at seg 0a000 refers to).
 There are some good tutorials and docs on using VESA modes, I suggest you
look at the filebase on your favourite programming BBS. Good luck =)

Once upon a time (Sunday, May 18, 1997 to be precise), John Gardeniers wrote
letter to Flemming Sondergaard about "Creating my own OS"...
'ello!
Indeed, the PC is popular, but I find it very hard to believe that such a
lousy system could possibly survive for very long. Sure, Intel keep pushing
the processor to even higher speeds, but they still haven't changed the
design radically. Deep down, it's still an 8086 CPU running my computer,
with all the limitations and stupidities that necessarily follow.
Instructions vary in length from 1 to more than 12 bytes because of all the
various prefixes needed. On the PowerPC, all instructions are 4 bytes (for
the 32-bit CPUs) or 8 bytes long (for the 64-bit ones).
You still have only 7 (somewhat) general-purpose registers of which you can
access bits 0-31, 0-7, 8-15 or 0-15. If you want to, say, copy bits 5-7 to
bits 26-28, you need about five instructions and an available work register.
The PPC lets you do this in one instruction without extra regs. (_and_ you
have 32 integer and 32 floating-point registers.)
The PC relies on instruction overlap which allows it to execute a maximum
of two instructions at the same time. The PPC can execute up to 6, _and_ you
have total control of when and how this happens.
I could go on forever, but I think I've made my point clear; the PC does
not stand a chance of competing against systems like the PowerPC. Especially
considering that PPC CPUs cost less to manufacture than PC ones.

 but for typing stuff like this, an old 8088 don't really have
any trouble keeping up. When you look at this stuff, what you
see is 7 bit ascii.... the rest of the 32 or 64 bits on your
hot iron is totally useless. By now, there are probly millions
of PCs in small businesses running spreadsheets like 123 that
have made bookeepers obsolete.  Now, as much as I might like
it, I don't think my business is *ever* gonna havta use even

be around a long time, and just get cheaper so that you will

What hardware platform are you using?
Will you have a kernel with loadable modules?
Will you have drivers for the majority of hardware on the market?
Will it be able to run software from other platforms?
What will be unique about it that other OS's don't have?
I'd say the BeBox and SGI workstations are a little more cutting edge.
Will OS/2 run all the software I use?
Does OS/2 support all the hardware I currently use?
Does OS/2 support CORBA?
How much do I have to spend to get all the functionality I want?
Can I play Quake over tcp/ip with it?
... Unix has gurus. OS/2 has evangelists. Windows has penitents.

Kind regards, Barry
