I haven't been following this thread, so I don't know what led to your
rant, and really it doesn't matter.


They were helping me troubleshoot a DOS 6.22 problem and I uploaded
some screencaps to show the problem in a format Lostgallifreyan wasn't
able to play, so he got all sensitive and started bitching at me for
assuming he knew how to get them to play. I guess some people obtain
knowledge at the expense of social skills and offer help on forums for
narcissistic instead of altruistic reasons. or as I call them - dorks.

With regard to your comment (above) about x264 (or is it h264?) not
being compatible with win-98, I'm not sure who's saying that, but it's
probably someone here with an anemic PC (pentium 2, 300 mhz or some junk
like that) and who's never tried kernelex and VLC (that is probably
about half the people who read this win-98 newsgroup).


Most likely.

I do a lot of downloading and I'm seeing more video's (movies, tv-rips)
being posted as MPEG-4 (x264) and not xvid, and a lot of other people


XviD is MPEG-4 too, though it really should've been called MPEG-3. In
the ITU naming convention, XviD is the H.263 standard and MPEG-4 part
2 (ASP) is the ISO equivalent. Just like H.264 is MPEG-4 part 10
(AVC). I find the ITU terminology a lot simpler to follow. Don't
attempt to make sense out of them, I regret ever taking the time to do
so.


are bitching about the end of Xvid in a lot of different forums (and I
don't know what their problem is), but win-98 and VLC can play 264 ****


Problem is they are change-resistant fanboys who have no dick. Do
yourself a favor and don't attempt to understand them either, I regret
ever trying.

So I download DOS 7.1, then what? Do I have to install this on a thumb
drive to boot from it, and then do I cd to the directory with the
program I wanna run?


The program is not a game, btw. It's an emulator that runs ROMs
(games).


You could boot DOS from a USB drive or CD, and then create a RAM disk
via a line in autoxec.bat. If your app requires TEMP space, then SET
the TEMP directory to your RAM disk. Otherwise, if your app writes to
some other directory on the disc, then copy your app to your RAM drive
and launch it from there instead. All this could be done automatically
via appropriate lines in autoexec.bat.

If you could be more specific, perhaps one of us could expand on this
for you.

BTW, how much disc space does your DOS app occupy and how much RAM
does it require?


The application itself is around 300 KB, the roms are between 2 to 6
MB. RAM usage shouldn't be above 60 MB.

I set up DOS 7.1 with Virtualbox because this was more intuitive than
having to restart the comp every time to get around issues. This
virtualization **** is kinda cool, the only disappointing thing is the
fact that I can't browse my regular OS from it. The only way I could
copy files to the virtual DOS is making a CD ISO of the directory with
my app and loading from there.

This has failed, though. There is no sound and the emulator freezes
the moment I tried to load a game. How do you set color depth on
Virtualbox btw? It says its on 32-bit and needs 16-bit but I don't see
such option anywhere.


ISTM that you could follow the procedure used by Seagate in its
firmware updates. These packages boot to FreeDOS. They then create a
RAM drive and copy their executables to it. The program is then
launched from the RAM drive.

Some CD ISO based update packages incorporate a 1.44MB floppy diskette
image, while others incorporate a HDD image.

You can see what I mean if you use IsoBuster, Winimage, and 7-Zip to
analyse Seagate's CD ISOs:

Which emulator? There might be a more elegant solution than trying to
run it in a DOS-like environment.

60 MB? Okay, not that surprised, even DJGPP stuff uses a lot these
days, but it seems overkill for a few MB of data.

Yes, of course.

You may be able to use MS NET and/or an FTP server. Check
lazybrowndog's networking guide. (Or if you later try VMware, then try
Eduardo's VMSMOUNT tool.)

Yeah, VBox has quite a few bugs in DOS emulation. If your cpu has VT-X
(which I guess not, sadly), it should work okay though. Too bad more
cpus don't support it.

In what, Windows or DOSBox? I'm not big on Windows internals, but I
think DOSBox uses SDL, and later versions (1.3 ??) are multi-
threaded / multi-core or whatever for better performance, though
DOSBox itself isn't. So maybe?? that's why? (Confusing.)

It was overkill actually, I set up a new VM with DOS 6.22 with 32 MB
of RAM this time and it works perfectly time. 60 MB was my upper
guestimate.

Good to know, but it's allright. I never used a VM before so I
completely missed the point behind it which was to isolate itself
completely from the OS yet be operated from it. I thought it would
just be another directory on my hard disk where the files can be
manipulated from my physical OS.

threaded / multi-core or whatever for better performance, though

In the DOS VM, but on DOSBox too and this has happened with other
programs too. Could it be that my audio drivers are multithreaded or
something? I'm genuinely curious. This hasn't happened to anyone else,
apparently.

Almost all old programs do not use multiple threads. Setting affinity
to a single thread (or using Windows compatibilities modes which does
this automagically) is a common technique to get games to work that
don't like multiple processors.
