assistant: Pointing to 0000 or having a value of 0000?  In protected mode there IS a
difference there, as 0000-0003 are considered null selectors...
If you want to use it as a real mode address while in protected mode, you
ave
to use the DPMI function "Segment to Descriptor" (Probably can be found on
he
Interrupt List)
You can't take the 30000000h directly.... Unless you had 1.5 GB of physical
memory, which is only practical on a Supercomputer... for a computer with
6MB
ram, the highest physical address you could get is 00FFFFFFh.  (even though
32-bit protected mode would allow 4GB of LOGICAL address space.)

nothing short of using a completely different format disk at low level, it
would be impossible to prevent someone from running diskcopy on it (unless

    Your Tsr alters a lot of registers without restoring them.  The computer
is almost guaranteed to hang.  If you are worried about using the Dos
stacks (which well you might be), set up a local stack.  BUT SAVE ALL
REGISTERS.
   I'm never quite sure what I get when I use the 'simplified
directives'.  Try
   cseg   segment
   assume cs:cseg
   org 100h
   Not necessary.  When Dos loads a COM program it sets all the
segment registers to point to the code segment.
;
;
;
    Save all registers
Restore all registers before exiting Tsr
You need to do things in a different order in order to do that.

Well, but if you just change the order of the pops (and certainly the pushes
too) you will not need that cli/sti pair. Well, unless one try to run your
code on a 8088 from a _buggy_ serie. As any move toward SS will automatically
disable the interrupts (even NMI) for the duration of the next instruction
that is supposed to be a mov to SP.  And other thing to consider is LSS. :)
Dropping cli will have good effect on protested mode systems (like NT). And
dropping sti will not open the floodgate if one happen to call that routine
with interrupts already disabled.

assistant: Certain things, particularly graphics, can be immensely speeded up when
written in assembly language... for example, if you look into high-level
language graphics routines, you'll find that 1. they probably have some
comparisons to determine what video adapter is present, and 2. they won't
translate very well from the assembly/disassembly code to the high-level
language.  If you write your own graphics routines in assembly language, you
can make your own functions, and if you're only using it on your own
omputer,
you can make it adapter-specific and not worry about checking to make sure
it's run on the right adapter...

assistant: These two are very slow, and use the stack... not only do you have near CALLs
to slow it down, you have multiple calls to int 10h...  My suggestion to
peed
this up is to use some REP MOVSWs, and eliminate most of the near CALLs...
also when you call the old Int 1C, you'll have to do a PUSHF before, since
he
IRET at the end of the previous interrupt routine will try to pop flags off
the stack after it pops CS & IP.  Another trick you might try is this:
when you want to go back to the old Int 1C, do this:
        PUSH    CS:[OldInt1COffset]
        PUSH    CS:[OldInt1CSegment]
        RETF
Then you'd let it do the IRET part, and it would think it was called directly
from the program, rather than from your interrupt.

Write your reply.

assistant: t
That doesn't surprise me.  Your three biggest problems are still there:
1. You're assuming DS will stay the same, which is NOT necessarily true,
especially in a timer interrupt.
2. You're not saving any of the registers you use...  a timer interrupt is
often called from the middle of a program, which expects the registers to
tay
the same... only interrupts which are never caused by the hardware can skip
saving the registers.
3. You're using int 10h calls for single characters, which is too slow for
se
in the timer interrupt...  see my previous message re using REP MOVSW
My "PC Interrupts" book (by Ralf Brown & Jim Kyle) lists this as an obsolete
call... it suggests using int 21h function 31h instead (DX is the number of
16-byte paragraphs to keep, so you can just do a SHR DX, 4 (if smart code
generation is turned on, it'll automatically assemble as 4 SHR DX, 1

Write your reply.

assistant: Hi... this program is full of bugs..!
needs to be proc far... since it can be called from anywhere.
you should preserve all registers - your interrupt routine should never leave
any registers with values other than what you started with. Push every
register that is modified and pop it before you return.
Keep your whole ISR in one procedure. Don't split it up.
DX contains the number of paragraphs to keep TSR, NOT the absolute location.
A paragraph is 16 bytes...
so, you should do something like:
mov dx,offset endofprog     ; end addr
shr dx,4                    ; divide by 16
inc dx                      ; add one to cover the last few byes.
which will select, at worst, 16 bytes too much. At the moment you're
selecting <codesize> paragraphs of memory - 16 TIMES too much.
there are just a few things, for staters - there's probably many more faults
yet.... but keep at it - you are getting closer, slowly.
