assistant: Hello All.
I was wondering if anyone could told me how to make a bootsector that loads
system files (for example: ibmio.com and ibmdos.com). And how to make
ibmio.com and ibmdos.com. I have already made a bootsector but it only writes
a message that this disk is not bootable, let me show it to you:

If you are "new" as you say, then don't try this at home. [grin]
Use a good graphics driver. There are several available, most quite
technical. Read a few and decide if this is what you really want to
do. If not, use the standard API calls.
What language is this?
Maybe you are refering to "DirectX"? Maybe "openGL"?
Lots... But are they any good? [grin]

But then Intel came with the 8088 (the 8086 SX if you wish), which had only
half the number of bits (of how do you call it) on the bus (so, the 8086 was
a full 16-bit processor, and the instruction set is exacly the same as the
8088's).
It's a bit like the 386DX and SX. The DX is a complete 32-bits system, the SX

Negative; they required that the motherboard be designed to support it;
before the 286, most manufacturers didn't want to go to the extra expense of
designing the more complex boards that this required, when they could get
nearly the same performance with the 8088.
Even today, I can take an 8-bit card that used to be in a PC or XT, and it'll
work in my Pentium-compatible system.  A few months ago, I had an old
full-length 8-bit CGA card on a Pentium board, to run a CGA adapter.  This
would not work if 16-bit (or higher) CPUs *required* 16-bit (or higher)
ds.
Not quite the only difference; the prefetch queue is also a different size.

I assume that b[var] is equivalent to MASM's "byte pointer var", and w[var]

No, they are not; the Intel CPU stores the least significant portion of any
item in the least significant memory location. Thus the value at byte pointer
var is 02Fh and the value at byte pointer var+1 is 02h.
BTW, I do not believe that these are the results you obtain with an Intel
CPU; with the first code fragment, your result should be AX = 02F10h, with
the second code fragment your result should be 0102Fh.

assistant: Replying to a message of Sam Izzo to All:
This has nothing to do with .COM or .EXE format; the clue to your answer is
in the last observation of yours that I quoted.
When DOS loads a program, it is given all available memory. Before you can
use the memory allocation function, you must have some free memory to
allocate.
Changing the heap requirements in TPascal did that for you, at load time,
before execution was passed to your code. In assembler, you must control that
all by yourself, or use linker directives to do it for you.

A COM program is allocated all the memory in the TPA. You must first
deallocate this memory then allocate what you desire.
Since a COM program runs in 64k it's pretty safe to deallocate all
but 0fffh pages above the PSP:0000h. However, if you want to
deallocate more, be sure to move your stack to a safe area...
In a TSR program, put your memory de/allocation code at the end
of the program as it can be overwritten when your done. Since,
you won't need it anymore. Again, be careful with the stack.

Write your reply.

assistant: I had the same problem. I've lost df's reply but the general idea of
 it was:
        .COM files don't have the info about their memory requirements
 stored in a header, so DOS gives them everything between the code and the
 video memory. Because everything is already taken, there is 'not enough
 memory' for other things.
        Well behaved programs will resize themselves (INT 21h, Function 4A -
 Modify Allocated Memory Block (SETBLOCK)) to the size needed for CODE +
 STACK + DATA.
        I guess that with .EXE's there is some kind of compiler directive
 or it auto calculates the size, but i don't exactly know.

Once the motherboard chipset is initialized, there's not typically a whole

which something is required (e.g. power management, changing video modes,

either uses its own drivers or does without the service.  The very simple
reason is that the BIOS services are typically (but not exclusively)
written for real mode for backwards compatibility reasons and there are not
really well established standards for general purpose 32-bit protected mode
BIOS services (some exceptions include APM and PCI APIs).
That tends to support the idea that Win95 is actually the world's largest
