Write your reply.

assistant: INT 21 is a DOS call, hooked in by IO.SYS at boot time. It is
a vector in low memory, at 0:84, pointing to code loaded higher
in memory. No, assembly is not the same between OS's. What you
are refering to is called portability, and assembly is far from
portable.

user: You are replying to All about "Static segment overlay".

Write your reply.

assistant: Hello All ...
A DOS program I'm developping needs some data only at initialization
time, and not after. Since this data isn't used anymore while the
program is running, I thought it made sense to try to overlay this
data with unitialized data that's only used _after_
Had this been a "one module program" there would be no problem:
INIT&BSS                SEGMENT
bss_1                   LABEL WORD
init_1                  DW 1
[ etcetera ]
INIT&BSS                ENDS
However, it isn't. Data comes in from many modules, so I went
searching for a way to overlay entire segments. Conceptually:
INIT                    SEGMENT WORD    PUBLIC
INIT                    ENDS
BSS                     SEGMENT AT INIT PUBLIC
BSS                     ENDS
The "AT INIT" (offcourse?) isn't allowed, AT only accepts an immediate
operand, but it is what I'm trying to accomplish. That is, I want the
BSS segment to reside at the same adress as the INIT segment, with the
linker allocating (and/or reserving though the EXE header) enough
space for the larger of the two. I tried fooling around with the
COMMON and VIRTUAL segment attributes, but to no avail.
This should be possible, shouldn't it? Using Turbo Assembler 4.1 and TLINK
7.00.
Thanks in advance,
Rene

Write your reply.

assistant: Replying to a message of Glenn Delahoy to Scott McNay:
It often takes quite a bit of time for a response back from hardware after an
OUT instruction. The JMP $+2 will clear the CPU instruction buffer, forcing
the CPU to re-read the subsequent instructions. This generally is more than
enough time for the response to be received back from the i/o port. In other
words...
Absolutely.

Write your reply.

assistant: Replying to a message of James Vahn to Rejean Lambert:
I think it would be highly unwise to rely on this being true forever. Any
unused port is free for use by any hardware device, unless it is reserved by
the CPU or system board manufacturer. In the latter case, it would be
suicidal to use the port to force a delay (remember, this is exactly what
happened when IBM decided to use the interrupt vectors Intel had reserved for
CPU use.. take a look at Ralf Brown's interrupt list to see the debacle that
exists today).

Write your reply.

assistant: Replying to a message of Tim Hutzler to Serguei Shtyliov:
Always a possibility, but one easily overcome by always using explicit
overrides: JMP SHORT $+2 or JMP NEAR $+3, for example.
Not really; since the prefetch queue must be re-read as soon as the JMP is
executed, the JMP instruction is virtually guaranteed to force enough time
until the i/o instruction has completed and the response can be read. Given
the unpredictability of hardware access time, it would be virtually
impossible, I think, to predict the exact number of NOPs that would be
required to produce enough of a wait in all instances.
The JMP has the added advantage, in situations where the memory footprint of
the code is an issue, of requiring only 2 or 3 bytes, whereas one byte per
NOP is always required.. a few bytes may not seem like much with the amount
of memory generally available today, but if everyone thinks that way every
time, total memory requirements will quickly build.

I seem to recall that 4F was mirrored on the motherboard in some
way and impossible to use in any real fashion..? I don't think
a card on the bus can use anything in that range, and if that
is true it means a motherboard manufacturer would have to be the
guilty party.
Here's a clip from the Linux kernel. He uses port 80h, which
shows in a port list as being used for DMA.. Any comments?

assistant: Hi Danny Phillips,
 I have no idea how linux handles low-level stuff but interrupt 21 is a gate
to dos interruts under dos so above example should not do whatever it does
under dos even if you use linux on a PC. Most probably only kernel parts
would allow an interrupt call as linux is not a real mode operating system
and there is no point in allowing the programmers reach that low level. You
should use the libraries instead provided that you don't try to enhance the
kernel. If there is a way to use bios interrupts under linux for PCs, your
code will be highly unportable (other unix clones won't be able to run it,it
won't run even on a non-PC linux machine!), and your system will loose
stability.
 Unless you have absolutely no other way, do not use interrupts and direct
hardware accesing codes under any multitasking os. it won't be safe.

old. Even if it is free, since 81h is already in use by a DMA controller, 80h
is one I would be absolutely sure to stay away from :)
