    Game freezing in DOS
    « on: September 27, 2017, 02:38:37 PM »
    Guys,

    I've got a problem with Wolfenstein 3D freezing the computer when I try to play it directly in DOS.  The sound card I've been using with it is the Sound Blaster AWE64 ISA.  I am still waiting for the Sound Blaster 16 to arrive.  Do you think the game won't freeze if the Sound Blaster 16 is used?  I am only able to get it working in Windows without it freezing on me.  From what I know, the in-game music is freezing the computer when Wolfenstein 3D is loading directly in DOS.

    Did you configure the IRQ, DMA, and IO Addresses correctly using the SETUP program? Or if it doesn't have one (I can't remember) do you have a proper SET BLASTER line when running in MS-DOS?

      What about CTCM and AWEUTIL /s? Are you running those programs in pure DOS before running the game?

      His brief answer tells me he's done none of the suggestions...

      Turns out wolf3d has no setup program and tries to autodetect, which would have made that one impossible to have done to start with as well...

      Which is why you need to do the settings manually...

        When I last ran Wolf3D, I ran it straight from Windows.  I will try to troubleshoot it later.  It may want IRQ5 for the SoundBlaster.  Since I just beat the game last Friday (finished the sixth episode), I'm in no big rush currently.  I will look into the BIOS and check the AWEUTIL and CTCM and make sure they're correct in DOS.

          I just ran another test.  At first it froze like before.  I also tried Spear of Destiny, which did the same thing.

          I booted into windows, edited the Autoexec.bat and Config.sys, removing the CD-ROM drive from them.  I have a backup folder with the CD-ROM drive in them, so I can go back to that.

          When it wasn't loaded, MS-DOS had more memory.  I tried to load Wolfenstein 3D directly in DOS, and this time it didn't freeze but ran in full.

          I have the following set for the sound card:
          SET BLASTER=A220 I5 D1 H5 P300 E620 T6

          My reason for using P300 for the midi is because the Roland SCC-1 is using port 330 for midi.  Nothing is conflicting with the SCC-1 so I have nothing to report regarding it.

          OK, was the CD-ROM driver being loaded into the HMA? You might try that to free up more conventional memory. (use LOADHIGH= instead of LOAD=) And lines like DOS=UMB could be  helpful for DOS-only mode as well. Of course make  sure HIMEM.SYS is loaded first.

            I was using LOADHIGH, BC_Programmer.  Even with that set, Wolfenstein 3D froze as it still wasn't getting the full memory it needed.

            Why not just play it inside DOSBox?

              Because I prefer the way it is in real DOS.  I don't want to accidentally go to Windows.
