My virtual #MSDOS system had gotten way too messed up, so I just had to start again from scratch. Memory usage already looks pretty good ... as I was able to put most of the drivers into high memory. I admit, using the 3K "cute mouse" driver from 2008 feels a bit like an anachronism, but yeah... I am cheating the system ^^. https://files.techhub.social/media_attachments/files/111/168/261/924/917/169/original/b1e6d090b4498d98.png https://files.techhub.social/media_attachments/files/111/168/290/901/228/250/original/d14ba901a6a509ee.png
