I installed winME on a 600mhz pentium system that had been running a toshiba dvd and a yamaha 2100ez. After having some problems with system locking-up, removed winME and system is now '98se again. I also have remove the yamaha to put in another system. Everything seemed ok until I installed a game which needs to run in the pure dos mode(Jetfighter 3 Platinum). While trying to figure out problem I discovered that dos does not recognize my cd/dvd player. I went to Toshibas site and downloaded drivers to supposedly get it to work in dos. During the loading of driver it says I don't have mscdex? OK....Where do I get mscdex? How do I get dos to recognize cd?
