Yes, probably.
Never heard of it.
Yes (Quake/2 has been out for quite some time now, and there's tcp/ip support
provided in a Dos box). And to stay on topic: it will run your dos assemblers
too <g>
:)
And concerning PowerMacs (which also have been mentioned in this thread),
there's a very interesting piece of software now called VirtualPC. It's a
really special emulator, in that way that it doesn't just emulate cpu
instructions, but it emulates all the basic hardware of a Pentium/MMX!
I think those programmer's must've had a hell of a job disassembling all
those components (or getting enough information about them) and finding out
their relations. And it must be really good at it's emulation of the 80xxx
hardware, as it runs Dos, Win 3.11, Win95, Win/NT, OS/2 and OpenStep
(straight out-of-the-box versions, not specially modified ones). Further it
also emulates an SB/Pro, an S3 videocard and all the ports (ie. ethernet,
modem, ...) from the PowerMac are transparently used in the PC-environment.
And they claim the emulator is so fast that it allows you to play PC-games on
a higher end PowerMac (or compatible)!
More info on www.connectix.com
BTW: I'm not saying this start a MCIBTYC-war (I'm currently still using a
PC), and I think this is kind of on-topic as it handles about the 80xxx
architecture & emulation of it on other platforms.

Write your reply.

assistant: Cameron, 12.06.97 ("Re: INT 06 - Invalid Opcode"):
Right.
Well, virtual address space is much more, but physical space is 4 gig.
The virtual size is much higher because you may use nearly as much page
directories as you desire, each page directory may point to 4 gig of
address space.
The cpu has something like that, that's the reason why you should load CR3
after applying changes to the paging structure. Loading CR3 invalidates
the tlb.
Sounds true ;-)

You may use C (like you do now) but without using standard io functions
(like printf). I do not write C programs but I think a C-compiler
generates ASM source code which you can scan for some hidden int 21h calls
(like 4Ch). Or you may try djgpp and change some parts of the source code
to not use dos calls.

It's not very hard to seperate fax connect from normal data connect, but
voice detection may be difficult, because a normal modem doesn't tell you
if there is a voice call. But you can send ATA in answer to a ring and
wait for a specified time. If there is no connect in that time then you
can assume a human caller.
Unfortunately your modem generates some noise while waiting for a connect

opyable.
sn't
Some cpc games used an interesting copy protection mechanism. It worked in
the following way:
-Take the disc an puch a hole in it with a small neadle (use an inner
 circle, because the outer ones contain the boot sector and the route dir)
-Search the disc for the sectors which are destroed now
-Write a little routine that test your disc for the damage to be exactly
 at this position. It's almost impossible to destroy another disc at
 exactly this position
Another effect is that disc copy will reject to copy this disc due to a
read error.
Anyway, if some guy cracks this disc checking routine your copy protection
is -aehem- ineffective ;-)

Of course CX has to change !
There is a difference between transporting a byte or a dword, as you know.
If the source says MOVB and you change it to MOVSD then you have to divide
CX by 4. BTW: Therefore you do not have to search for the line assigning
CX, you just have to shift CX right (twice, will only work if
CX MOD 4 ==0). And the REP MOVS? uses ECX if you use the address size
prefix (67h, uses ECX, eSI, eDI instead of CX, SI, DI).

A> The CPU doesn't permit a single-step interrupt immediately after a mov SS:
B> Most debuggers know that to execute, they themselves need a valid stack.

Write your reply.

assistant: Most debuggers execute the instruction after the mov SS: for 2 reasons:
instruction
They _know_ that whilst ss: has changed and SP has not, the stack is not
valid. They also _know_ that the very next instruction is usually a
SP-modifying instruction, so they simply ASSUME that is the case and execute
the next instruction without breakpoint. That way, the debugger assumes that
the stack will again be valid, and continues on.
There are also issues with the CPU itself - I'm not sure, but I'll bet that
most CPU's would have an interesting time if you tried to insert a breakpoint
instead of the mov sp command - it would probably execute on early 8088/8086
(the ones without the automatic protection) but with all later 8088+, it
would be real curious, since interrupts are disabled at that point, who knows
what might happen.
Remeber that in order to execute a breakpoint, the first thing that happens
is the return address is put on the stack....but right now SS:SP isn't
valid.... even if that works, the first thing a breakpoint handler usually
does is enable interrupts... but SSP:SP _still_ isn't valid....
It might be interesting to set up some test code to experiment with here, but
I'll give you even money you just crash, either just after soon into your
breakpoint handler.

Write your reply.

assistant: The touchpads I've seen work exactly the same as a mouse - you can even use a
standard mouse driver to run them, and program them thru int 33h.. so there's
no easy way of telling a touchpad from a mouse, as far as I know. Perhaps one
of the mouse driver functions might help - but don't count on it.
If you become aware of any touch pads that use a system other than "use a
mouse driver" I'd like to know about it..
