Re: Dos 6 conventional memory tricks

1. Is there a reason why you are calling menu.bat from autoexec.bat rather than creating the menus in autoexec.bat and config.sys? So that if you press X to exit the menu to the prompt, you can type menu to get back into it without restarting your computer or re-running your autoexec.bat stuff. 2. …

Thanks, could you please clarify how to do this? Do you mean that I should edit my PIF file from Windows 98? I meant customizing/creating autoexec.bat and config.sys like you did, then creating a file like this with a name like menu.bat , then starting it from autoexec.bat : @echo off :TOP cls echo …

I assume that COMMAND.COM is being loaded twice? While it's not eating conventional memory, I'd still like to know why this is happening and if it could cause any problems (I'm trying to learn how this stuff works, not just how to use it). I'm booting into DOS using a PIF file created by making a …

Another thing you could try. If your COMMAND.COM is taking more than 816 bytes of conventional memory, setting 4DOS 8.00 (the "Free 4DOS" link at https://www.4dos.info/v4dos.htm#751 ) as the shell= can give you tab completion, command history, and a bunch of other nice stuff while also freeing up …

It tells me that SHSUCDX can't open CD driver optical That was an example of what they use. You need to use the same CD drive identifer you're currently feeding to MSCDEX. (/D:MSCD001 rather than /D:OPTICAL) The /D:mscd001 on your oakcdrom.sys line in config.sys creates the name and then the /D: …

You mean I should change it (by adding your lines) to : device=c:\windows\command\display.sys con=(ega,,1) DEVICE=C:\WINDOWS\HIMEM.SYS DOS=HIGH,UMB DEVICE=C:\WINDOWS\EMM386.EXE NOEMS Country=351,850,c:\windows\command\country.sys Edit : I did it and it worked, I can now launch Descent :) Thanks! …

Hi! I'm having the same problem you had, but I don't know how to "call HIMEM and EMM386". Is this something I must do in autoexec.bat? They go in the other DOS startup config file: config.sys Something like this: DEVICE=C:\WINDOWS\HIMEM.SYS DOS=HIGH,UMB DEVICE=C:\WINDOWS\EMM386.EXE NOEMS The …

I thought BUFFERSHIGH could put the buffers in upper memory. I haven't looked at my config.sys or autoexecs in decades now, but recall that we would do this in msdos 5.0. I think it actually works only on Windows 9x (DOS 7.x), and FreeDOS (possibly since certain versions). Huh. You're right …

...like the BUFFERS and FCBs. I thought BUFFERSHIGH could put the buffers in upper memory. I haven't looked at my config.sys or autoexecs in decades now, but recall that we would do this in msdos 5.0. Possibly. I am quite tired right now and without it being easy to boot it up and check, it's …

What do you want in a DOS installer wizard?

Posted on 2020-08-29, 18:20

One of the hobby projects I've started to poke at again (mind you, very slowly) is an effort to build an installer builder for DOS. (InnoSetup, NSIS, WiX, and MS Setup 2.0 serve everything from Windows 3.1 onward, but I couldn't find anything for DOS that was both legally free and as polished as the …

I've been using qemm since it originally came out. Never had a problem with compatibility. I found that my AST Adventure! 210 didn't like QEMM97 (It rendered it unbootable) so I just went for borrowing stuff from FreeDOS distros that's more space-efficient and can load itself high more completely …
