This really depends on how much ram you have free in the upper memory block. Usually this would be 128k at the most. I can do a lot with that. I spent ages looking for the smallest functional drivers I could get away with. For example, BENQ.SYS is about 5k and I use it a lot with CD ROM drives using MSCDEX.EXE. I find that if you use the tiniest device drivers available, you can put a lot into these upper memory blocks! -- http://www.munted.org.uk One very high maintenance cat living here. ------------------------------------------------------------------------------ _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
