REM Device Drivers

  
:-/Need help getting more memory. When I run Scandisk I get the message that I don't have enough memory and get this message: "You need to REM some Device Drivers from your CONFIG.SYS file. Or, in your CONFIG.SYS, you may need to load EMM386.EXE Driver to load your other Device Drivers into Upper Memory Blocks using DEVICEHIGH= statements".  I need to know step by step how to do both these functions.  

HELP!!!    :-/
