Hi, all implementers or programmers: I feel very strange that why DJGPP use VCPI to swap in-out the memory? Why the sequence of memory usage is VCPI then XMS then other....? The performance for a 4MB ram machine use only XMS is faster than XMS +EMM386 (or 386MAX or QEMM). Almost better than 200% ~ 300% ! Is EMM386 will disable XMS or DJGPP's GO32 will confilt with EMM386 ? otherwise, why use EMS paging to allocate memory? please enlighten me :) tony -- >> Anthony Lee, << << Institute of CSEE, National Central Univ | ARPA: cs8023 AT mbox DOT ee DOT ncu DOT edu DOT tw>> >> Chungli, Taoyuan, Taiwan,# Free China | oper2 AT ncuee DOT ncu DOT edu DOT tw << << Republic of China (ROC) # Chinese Taipei| oper2 AT ncuee2 DOT ncu DOT edu DOT tw >>
