This is the CD ROM Diver for the Compaq LTE 5000. DOS (i.e., ver 6.22) must first be loaded, then Win 3.1 (trust me on this one!!!). Then, and only then, this driver. It comes with a read me file and instructions on modifying the config.sys - which must be done before it will recognise the new driver. From then on you can load the upgrade version of Win 9x from CD ROM on top of Win 3.1. Any problems (and you probably will have!, e-mail me - email@example.com).
