A .com is a binary image file. It is loaded into memory exactly as it appears
on disk, and there is no program header to do any reallocation of memory. A
.exe is not; segment relocation is necessary (eg. set up the stack segment)
so there must be a header, and that is where memory reallocation is done.

Write your reply.

assistant: Replying to a message of Sam Izzo to All:
Yes, it is necessary, because PIC2 actually signals to PIC1 that an interrupt
has occurred, and it is actually PIC1 that informs the CPU that an interrupt
has occurred. This is the heart of "INT02 redirection" that confuses many
people. My memory is a bit vague, but I think this is how it works:
INT02 is not actually redirected anywhere; rather the INT09 bit on PIC2 is
latched onto the INT02 line on the system bus, while the cascade bit on PIC2
is latched onto the INT02 bit of PIC1. When PIC2 issues an interrupt, it
raises the cascade bit, which in turn raises an INT02 on PIC1; it is actually
PIC1 that raises the INT signal to the CPU by raising its cascade bit.

One can get around this partially by both checking the flags to see if

Pentium-class or better.
Do you know if ports 22h and 23h are always used the same way in all of the

Hi Ben;
What you are describing is a FIFO, or queue. They both work the same
in that the first element in will be the first element out. Since you
mentioned the word, "buffer", then I will presume that you are
thinking of a FIFO stack.
Also, when you stated. "Any data that could not fit in the buffer
would fall off the top." Are you saying that (overflow) data will be
lost? I don't think you want that, but I need to ask.
Second, since this an an assembly echo, can I presume that you are
developing an assembly subroutine for a higher-language mainline, or
will it be all in assembly?
Anyway, if you want a FIFO buffer, you need to have two pointers.
And, you will have at least two subroutines: One to pass the data
into the buffer - called 'put', and one to pull it off - caled 'get.'
You also should have two other functions: One to test if the buffer
is full, and the other to test if the buffer is empty. However, you
can make them part of the 'get' and 'put' subs, if you wish.
If this is what you are looking for, let me know and I can talk about
implementing the pointers.

Okay, currently it

2. Yep, we got a dir command!
3. No, we don't got a format command... that's the easy part

Write your reply.

assistant: I don't think you described a circular buffer..
Whadya mean: 'buffer is empty' head=tail ?
That's a stacked buffer.
Otherwise you're right, fiddling with the pointers might not be
easier but certainly faster than moving gobs of data.

BOFAQ is a good document, fairly well maintained and available

Write your reply.

assistant: Hi..
it
I'm afraid you are somewhat incorrect. Instead of starting a mud slinging
contest, I will state my sources here. Please bear in mind that we are
discussing the disabling of NMI's related to ram parity errors, not NMI in
general.
1. Book: "The Undocumented PC" edition 1, page 671. Describes port 61h.
bit: R/W use
7     r  RAM Parity error present
6     r  I/O Parity error present
5     r  Output of timer 2
4     r  Refresh request clock / 2
3     rw enable I/O parity check - Generate NMI if error
2     rw enable ram parity check - Generate NMI if error
1     rw speaker data enabled
0     rw gate timer 2 on
This book makes copious references to NMI in chaper 17 'Interrupt control and
NMI'. This book does not mention port A0h for NMI on an XT.
2. Ralf Brown's interrupt list, ports.lst, edition 56, table P102.
(Essentially repeats data above).
Ralf Brown also documents port A0h. He says if you set bit 7 to a '1' then
NMI is prevented from reaching the CPU.
The difference is that if you use port A0h to disable parity NMI's, you also
disable NMI from the math coprocessor. If you use port 61h, you can disable
parity-NMI's but still permit coprocessor NMI's through.
So it depends on what you want to achiveve. In the context of a discussion on
ram parity NMI's, port 61h is clearly the better way to go about doing
things, and that is why I wrote what I wrote, and why I feel your solution is
somewhat worse. Granted, it doesn't make much difference if you don't have a
mathco!

Ok, here's a partial response on that; the two tests shown above are pretty
much good for determining that the CPU is not an Intel chip, and that's about
it; can't really be certain about any other meaning.  I've had my doubts
about these two tests for a while.  It doesn't help that UMC chips aren't
available in the U.S. (supposedly due to copyright violations), so can't be
tested easily by folks in the U.S.
Right now, I'm trying to test another method that will (hopefully) detect
EXACTLY what CPU is being used, with a single test, and even identify chips
that the routine doesn't already have a name for.

Write your reply.

assistant: Replying to a message of James Vahn to Darryl Gregorash:
Ummm.. a stack _is_ a LIFO buffer.. you read from and write to the stack
using the "head" pointer. If you re-read, I said "write at the tail, read
from the head", and that is a FIFO buffer, a queue.
The only reason you ever need a separate "tail" pointer with a stack is in
the case of a circular stack, and then only if you wish to prevent data loss
after a wrap-around ([head+1]mod stack_size = tail, the stack is full.. you
cannot push more data onto it without losing the value at the bottom of the
stack).. not that I can imagine why one would want to prevent such overwrite,
but I suppose it might be desirable in some cases.
Take another look at my code.. it is much easier than fiddling with gobs of
data. Just as I used LODSB to read from the queue, I would use STOSB to write
to it :)
