PMMOUSE is the PicoMEM Mouse driver, it is a modified version of CTMouse. There is no need to enter any port and IRQ, everything is detected automatically.

PMEMM is the EMS Driver, a modified LTEMM Driver supporting the EMS Ports detection and test, plus 4Mb of EMS.

You need to add it in CONFIG.SYS, like this :
DEVICE=PMEMM.EXE /n

/n means no RAM Test.
The Driver is able to detect the PicoMEM, the EMS Port and Address. Then, /p and /i parameters are not needed.

If you want to experiment with UMB, to extend the RAM above the 640Kb, you can go through this Vogons forum subject:

As the PicoMEM is ne2000 compatible, PM2000 is exactly the same driver as the ne2000 With parameters auto detection (IRQ and Port)
Then, unlike ne2000.exe, it does not load the driver if the ne2000 is not detected.

I will regularly update the tools to add init fonctions when DOS is Booted.
