MMD.386 virtual device driver is not loaded .

I tried to run microsoft power fortran on window XP. And I have got message returned as follow :

MMD.386 virtual device driver is not loaded .

Recommend to set \'DEVICE=<Directory Specified in Setup for Binaries>\\MMD.386\'  in SYSTEM.INI .

How can I do that ?  

Can anyone give me answer ? Thank you .
