No.  You've spotted an error.  That second +100 should be replaced with a

When the program starts, SS = CS = DS and SP = 0FFFEh (a zero has already
been pushed onto the stack.)  Since we're resizing memory and making it
smaller, the stack is suddenly outside our allocated memory block.  Then,
when we do the memory  allocations next, since the OS now thinks that space
is free, we might very well get the stack pointer pointing to one of our
data buffers!  Clearly, this is a disaster waiting to happen.  Better is to
resize the memory to include both code and stack, and then adjust SP.
That's correct.  However, if you look farther down in the code, you'll see
that I used [si] instead of [di-320] a total of three times.  The
instructions to load si takes six bytes, but each use saves two bytes, so
it's a wash.
No, I'm afraid not.  I have no FidoNet address anymore -- only internet.
That address is beroset@mindspring.com.

NMI.
FYI, there is a way to disable NMI on many motherboards.  Writing to port
0x70 (which is one of the ports used to access CMOS RAM) with the high bit
set causes NMI to be disabled on most modern motherboards.  This standard
was set by IBM in the PS/2 series and was adopted by many other
manufacturers.  Unfortunately, other good ideas from IBM, like the watchdog
timer, did not catch on.

Write your reply.

assistant: I checked my Intel Handbook on these processors and up to 386DX and they
all can be interupted between those two instructions... As for testing
that in Debug.EXE that's another matter. Remember, Debug uses that same
stack. When single tracing, Debug pokes the trap byte into the next
following instruction. Then it sets the registers to the last saved
values from a previous single trace and jumps to that address. Once
that instruction is completed it hits the trap instruction next. The
trap interupt occures. It saves the values of the current registers and
then fallows the routine to display them to you. Odviously, if Debug is
using that same stack when doing a trap interupt it had better check
ahead and make sure the stack is a valid one. Debug itself jumps over
them two instructions in a trace trap. Forcing a breakpoint overrides
that.
There are a number of ways to do that. In multitasking on a PC is not
possible. It's a single tasking processor. Basically, it task switches
very quickly from one task to the next in a daisy chain fashion but
it does not do two or more tasks at one time. Keeping this in mind,
there are a number of ways to interupt a processer every so many
clocks, instructions, or time intervals to make it switch from one
task to the next. While on SOME motherboards it is possible to use
the NMI for a multitasking interupt, it's not an absolute for all of
them...
If your curious, try using debug to INT 02h from plain MSdos.
(NMI interupt vector) If you don't get a reboot, look at what
it says on the screen. I bet you'll find those words in BIOS rom
somewhere.

Write your reply.

assistant: Sidebar to the discussion:  OS/2 and NT are pre-emptive multitasking
Operating Systems.  The BIOS is not reenterant code.  Therefore
BIOS code cannot work in a pre-emptive OS.  This is not true of
Win 95, DOS, and Win 3.1 which are not pre-emptive MT systems.
Note that the Win 95 manual says it is a multi-tasking OS.  But it
is really only a Task Switching OS - which can execute a non-
reenterant BIOS.
  The BIOS is used for the booting of the OS - when the OS is not yet
operating in a pre-emptive MT environment.  The vectors used to access
the BIOS routines are changed to code provided by the OS as it loads.

Write your reply.

assistant: Replying to a message of Glen McNabb to Scott McNay:
All Intel processors starting with the 80286 place the PUSHed value on the
stack before decrementing SP; that is common practice, but the 808x/8018x did
it the other way around: decrement SP and then write the PUSHed value to the
stack.
In the above code fragment, the 808x will thus do this (assume top of stack,
SP=0FFFFh at the beginning):
PUSH SP                 1)  SP <- 0FFFDh
                        2)  write value of SP to stack, ie. OFFFDh
POP AX                  1)  AX <- 0FFFDh
                        2)  SP <- 0FFFFh
This code sequence *should* be functionally equivalent to MOV AX,SP, but on
the 86/186, it is not.

Exactly; DOS merely assigns all available memory in one block to any program
it loads, and it is then up to the application to manage what it has been
given.
In this case, we wish to give up some of that memeory so we can request
memory for a different purpose. In a .exe, you can achieve that with linker
directives, in a .com you must write the code yourself.

AB> What does LES do?

Write your reply.

assistant: Replying to a message of Arnoud Bakker to All:
It loads the segment:offset of a data variable into ES and a scratch register
you specify. Thus, if THIS is a data variable, "LES BX, THIS" loads the
segment of THIS's location into ES, and its offset into BX. That is, after
executing the instruction, ES:BX is a pointer to the first byte of THIS. An
equivalent 3-instruction sequence is:
MOV BX, OFFSET THIS
MOV AX, SEG THIS
MOV ES, AX
Related instructions: LDS, LEA. LDS accomplishes the same as LES, but the
segment value is placed in DS rather than ES; LEA merely loads the offset
into the specified scratch register, as in LEA BX, THIS.
LEA/LDS/LES are far more flexible than equivalent MOV instructions, because
you can use indexed mem operands, which you cannot use with the MOV. For
example,
LEA BX, THIS[DI]                 legal
MOV BX, OFFSET THIS[DI]          illegal
