Installing and Exploring Mouse Drivers for DOS 

Thanks ✌️

Thanks for adding that!

I'll have to take a look

Me too, first 32 bit CPU just arrived, time for an UPGRAYEDD!!

@@TemporarilyOfflineRetroTech I use the PS2-Part of the Cutemouse-Driver in some of my applications without to start the mouse driver. My routine use the PS2 mouse user device handler from the bios without to use a software interrupt for mouse support. The Cutemouse-Driver use interrupt hex12 and support software interrupts with int hex 33 using a terminate and stay resident(tsr) part. My applications stop the device handler at the end. This is the different.
