For others, the qt5core fix is linked from https://github.com/bitwiseworks/qtbase-os2/issues/121
That may be an option, but I think it is better to try to learn to understand how memory and swapper work.
I don't know yet, but doing this works very well for me.
You can try this, rename the two lines of the config.sys
1- rem MEMMAN=SWAP,PROTECT
and
2- rem SWAPPATH=C:\OS2\SYSTEM 2048 2048
Copy this lines after that:
MEMMAN=SWAP,PROTECT,COMMIT
SWAPPATH=C:\OS2\SYSTEM 402048 402048
SWAPPATH=C:\OS2\SYSTEM 311286 311286
MEMMAN=SWAP,PROTECT
SWAPPATH=C:\OS2\SYSTEM 402048 402048
SWAPPATH=C:\OS2\SYSTEM 311286 311286
MEMMAN=SWAP,PROTECT,COMMIT
SWAPPATH=C:\OS2\SYSTEM 402048 402048
SWAPPATH=C:\OS2\SYSTEM 311286 311286
MEMMAN=SWAP,PROTECT
SWAPPATH=C:\OS2\SYSTEM 402048 402048
SWAPPATH=C:\OS2\SYSTEM 311286 311286
Doing this increases my memory by about 200mb.
Try it, the speed, and lightness is never seen before.
I do not need any patch for the processors for now.
Set the virtualaddresslimit to a value that works for you, and you're done.
I now have 1688, but I still have this under observation.
