Running an old DOS program

You are the classic OS genius, figure out how to get the latest **** to work without it needing to be a hassle 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. |

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: http://seagate.custkb.com/seagate/cr...p?DocId=207931 - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

I am the one here that Running MS-DOS 622, I ask him to send the name of the Game, Now he needs to Zip-File it, and send to:: http://hot-text.ath.cx/upload/ To see if have bugs in the DOS.. :/ |

Hi,

Okay, not that surprised, even DJGPP stuff uses a lot these days, but it seems overkill for a few MB of data. 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. Yes, of course. 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. 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.) http://lazybrowndog.net/freedos/virtualbox/ 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. 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. |

Hi,
On Mar 11, 7:57*pm, Industrial One wrote: I managed to install Soundblaster finally (I hate having a thousand choices) and figured out why the sound was cracking up. When I set core affinity to 1 the sound stopped crackling and was perfect. What does core affinity have to do with sound quality, does anybody know? 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. 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.) http://lazybrowndog.net/freedos/virtualbox/ 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.

I'm genuinely curious. This hasn't happened to anyone else, apparently. |

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. |
