Maybe I should try qemm 8.03 from this webpage: http://www.chsoft.com/dv.html Afaik this software gives big memory boost, but some games will crash.

Mouse driver works fine :) Other software like Dos Navigator and Ufo2 (terror from the deep) works too. In fact my problem is: Adding lbacache could improve system performance so I could kill aliens faster :) All I need is to recover some memory for cache. -- Best regards, up mailto:[EMAIL PROTECTED] ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Freedos-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-user
