Hmm, I'll post mine when I get home today... both my autoexec and config are pretty complicated menu option deals 😁 I get LOTS of memory with QEMM, and I bypass the SB16 drivers with SBMIX 😀

Played around a bit more, used DOSMAX as well.

608K free conventional memory and 718K total under 1MB.

Ha, well I get 625K largest executable program size! Beat that! 😉

We should have a "How much memory can you get with X machine and so many device drivers?" thread 🤣

The difference between yours and mine is, I have no CD driver (separate menu option), and I use SBMIX (doesn't install into memory) instead of Creative's mixer drivers. Also I use QEMM but I have no idea how much of a difference that makes.

For XMS setting: 556K free conventional memory

Here are my multiple-choice files 🤣
They need some editing depending on the hardware combo, but you get the idea... not many fancy stuff included 😊
On my systems with UMBs activated I get more than 600kb of conventional memory, never needed more. Getting UMBs under DOS is mandatory 😀

Good stuff

Also I fiddled around some more, got it to 751K under 1MB and 619K free conventional!

I use a modified version of the one Phil provides in his DOS toolkit.

I wish I understood what these all mean. I never grew up with Dos, so I don't know how to use it. I am trying to learn now and trying to get my first dos machine built. But I have do idea what I'm doing 🤣. Hopefully I'll be able to post my own settings in here soon
