1. If you ve been using previous version of LINKUP make sure you delete all the old LINKUP files from your hard drive They would probably be in a directory called LINKUP INSTALLING THE LINKUP FILES YOURSELF 2 Place your backup copy of the LINKUP disk in Drive A 3 Type the following DOS commands at the command prompt c makes Drive C the current working directory md linkup makes a new directory called linkup or whatever name you prefer unless a directory by that name already exists copy a c linkup copies files from Drive A to the directory on the hard drive 2 4 Modifying Your AUTOEXEC BAT File You might need to use a number of DOS commands to set up your system for LINKUP If you add them to your AUTOEXEC BAT file they ll run automatically when you turn your machine on and you won t have to type them in again every time you run LINKUP Reboot your PC after modifying your AUTOEXEC BAT file If you don t know how to create or edit the AUTOEXEC BAT file See your DOS manual s sections on the AUTOEXEC BAT file and the DOS editor program EDLIN 2 4 1 DOS PATH AND APPEND COMMANDS You might want to add these lines to your AUTOEXEC BAT file so you can access LINKUP files from any directory or drive on your machine Otherwise you can access LINKUP only if you make your working directory the directory LINKUP was installed in path c linkup allows DOS to find the exe f2.
