How do I disable these so I can get Ultima VII/SI to run thanks ?

modifying the config.sys and autoexec.bat

I had to completely uninstall qemm.. my windows 3.11 stop working.

You can use a multi config config.sys so you can choose at boot time your configuration.

You can also use a floppy boot disc image.

Instead of a multi-option config.sys or a floppy, it's also possible to just load EMM386 on demand when you need it if you use a device driver loader like Devload, available from https://www.ibiblio.org/pub/micro/pc-st ... vload.html

For example, I have the following in a batch file called ems.bat in my path along with devload:

Code: Select all

@DEVLOAD.COM /H C:\WINDOWS\EMM386.EXE X=CE00-CFFF I=B000-B7FF I=D000-EFFF NOTR
@C:\WINDOWS\EMM386.EXE

Doing it this way avoids the performance hit of having EMM386 running unnecessarily, and won't delay your boot sequence with a menu. It doesn't even have a larger memory footprint this way, I still have 620 KB of conventional memory free even with EMM386, cd-rom and mouse drivers etc. loaded.
