Installing MASM for ECE291 at home is easy. You will be running Masm and CodeView from a DOS shell. You, therefore, do not need to install all windows files. For my installation: Platform=MSDOS/Windows Windows=NO PWB=NO Mouse Driver=NO MASM=YES HELP=YES Samples=NO There are a number of environmental variables that are *not* set automatically by the install program. Specifically, you'll want to append your AUTOEXEC.BAT with MASM611\BIN\NEW-VARS.BAT. (As noted in the setup program, This does *not* happen automatically). This can be done with the command: type masm611\bin\new-vars.bat >> autoexec.bat For a typical Windows95 configuration, you do not want or need to alter config.sys After running your autoexec file, the path will include MASM.
