assistant: Hmm, you could check out that Table Assembler (TASM) that gave everyone
  a headache a while back! :) Using "tables" it allows you to create your
  own code templates to generate code for various CPUS. Such as 6502.
  The author of the Micro-C compiler also has some assembler or something
  which supports various CPUS. I'm not to sure, you'd have to double check.
  Cheers, congrats, bye.

Write your reply.

assistant: MS-DOS's DEBUG program only supports 808x instructions, but checkout the
 DEBUG in OpenDOS! It also supports 386+ instructions and even Pentium
 instructions and everything else in between!
 The only downside is you can't actually see the registers in the R listing,
 only the standard 808x ones. However you can assemble and dis-assemble the
 code and even modify the registers with R.
 ie:
 A
 mov    EAX,ABCD1234
 R EAX
 EAX ABCD1234
 :
 Since OpenDOS is really Novell DOS, I imagine Novell DOS / DR-DOS has the
 same capabilities.

Write your reply.

assistant: Yep, it's a 386+ prefix that would allow DWORD sized chunks of memory to
 be moved instead of WORD sized. (Possibly other things as well)
 ie:
    REP MOVSD       ;mov a DWORD chunk on a 386
 Could be done as:
    db  66h         ;386 prefix
    REP MOVSW       ;to 8x code to move a DWORD chunk
 DJGPP Is a 386 C compiler isn't it? As such I doubt you'll be able to get
 rid of it. Unless you can over-ride 386 code generation and use 808x code
 generation instead.

 Ahh good. Now you see what I mean by the registers being toasted. The hard
 part is that some shells/DOSs seem to save them for you. Such as OpenDOS,
 it returned from the call ok and so it would seem with 4DOS. Only MS-DOS
 seems to crash everything, since that's the bottom line I guess play it
 safe and save them.

Write your reply.

assistant: Bonjour David,
 Don't know about 7, but I know a bit about 6. When the CPU encounters an
 instruction it doesn't support or understand it calls this interrupt. By
 hooking your own code there, you can provide a safe mechanism to reset the
 machine when such instructions are encountered.
 The "invalid instruction" dialog that pops up sometimes in Windows when
 your DOS session crashes. or the GPF or when EMM386 takes a hit and offers
 to reboot your machine.
 Hmm, just theorizing here, but when the int is called it will be pointing to
 the "instruction". So, if your handler looked at this instruction, you could
 perform some action based on it. Thus you could create your own special
 CPU instructions.
 Cheers,

Write your reply.

assistant: Hi Balog or is it Paul or Paul Balog? :)
 Really? So you mean that a CLI doesn't really disable the interrupts but
 just puts them on hold? So, say I press keys on the keyboard would that
 generate a backfill of interrupts that get processed when the STI is
 encountered?
 I was thinking that the MOVSW to scroll the screen would be pretty fast in
 itself. So I figured if I disabled the interrupts during the retrace check
 I'd be sure of doing the dump the moment the beam is at top.
 Perhaps it doesn't really matter, without the CLI/STI pair the program works
 the same. What would be better probably would be to change the MOVSW that
 scroll the screen into MOVSD.

assistant: Hi Barry,
Thanks Barry. I've archived the file for possible future use but at this
stage
I've opted for adding three functions to my original program (this particular
one being a super simple TIC file processor). During a normal run (no command
line switches) it saves the return code to a file before exiting. There are
two
command line switches which utilize that saved return code. By doing it this
way I not only get around the original problem but I can use the saved code
in
a number of different ways and in different batch files. Functionally it's a
bit like having an environment variable which remains even after turning the
computer off. I'm quite pleased with the results. :-)

Write your reply.

assistant: Hi BRAD,
If you're prepared to accept the fact that assembler is completely
unforgiving and generally not as easy to use as a higher level language it
will reward you with faster programs, as well extremely compact programs.
Obviously, just how fast and how compact will depend on your particular
programming skills.
If the current version of MSDOS was written in assembler you would only
require one disk to distribute the uncompressed files.
Beware: That "total control" you get with assembler is the same reason it's
unforgiving. Think of assembler as a high performance sports car. Great for
getting places fast and terrific cornering but hard to take the family on
holidays. High level languages are more like the family station wagon. Good
and versatile but with distinct performance limitations.

The first one wouldn't, since diskcopy copies ALL sectors of the source disk,
regardless of whether or not they're marked as used.  I'm not entirely sure
what you mean for the second one, so I don't know whether or not it would get
past diskcopy...  I know of a trick used in Ultima IV that can detect the
original disk, and diskcopy wouldn't work on it...  I found out by running
Turbo Debug on it that it does some low-level disk access to load part of the
program, and it verifies the disk with a couple of different check with
different data in the area pointed to be Int 1Eh.... If I remember correctly,
the first check was done with 1024 bytes/sector and a gap length of 80h... I
think diskcopy assumes the bytes/sector to be 512, and the gap length the
standard for the size of diskette.  I also discovered when doing a scandisk
f
it, that there was a section marked as bad, which is probably where this
"secret" data is stored, so that it won't accidentally get overwritten, but
the FAT table wouldn't tell you where to find it.

Write your reply.

assistant: On (08 Jun 97) Martin Preuss wrote to Tom St Denis...
4 MB pages are useful primarily for dealing with memory that won't be
swapped.  For instance, if you have a video card with 4 MB of RAM that
you want to mark as usable pages, but obviously will never swap to disk,
you can do that with either one page of 4MB, or 1024 pages of 4K each.
Marking it as a single page of 4MB simply saves a great deal of space
for the page table entries themselves.
Likewise a typical OS will have a few megabytes of code that can't be
swapped out.  Again, you can create one big page that covers this entire
chunk of code rather than using thousands of page table entries up, even
though you're never going to swap any of it.
Finally, even if you do swap some code out, you sometimes _need_ to have
an entire system in physical memory before any of it can be used.  For
example, consider booting OS/2 straight to a command line.  Then later
you run a program that uses windowing.  OS/2 has to page in pretty much
the entire windowing manager before it can run the program at all.  You
can page that in as either several thousand 4K pages, or one 4M page.
(Offhand I'm not sure if it occupies a full 4M or not, but it wouldn't
surprise me a lot if it's close to that, at least while it's starting
up.)
Depending on how the system is designed, there's a pretty fair chance
that loading one 4M page from disk will be considerably faster than
loading thousands of separate 4K pages instead -- to the point that even
if you only really needed, say, 3M, it might still be faster to load a
4M page instead of 3M worth of 4K pages.
    Later,
    Jerry.
