Note The Readme.1st file inside the zip file explains what to do.
1) Copy files FWS2CD.SYS,FWS2ASPI.SYS and MSCDEX.EXE to your root directory.
(which is C most of the time)
2) Insert into Config.sys the following
DEVICE=FWS2CD.SYS /D CDROM1
3) Insert into Autoexec.bat the following
MSCDEX /D CDROM1
Good luck..... Email me if your have questions
