Folks According to LIM EMS3.2, the page frame in the conventional memory maps only 4 16K pages. I have read some material that EMS4.0 allows non contiguous page frames and allows access to more than 4 physical pages. In 3.2 I can find the address of each physical page by offseting n * 16K from the page frame to get at address of the physical pages. How can I do this with 4.0 (find page addresses) with non contiguous page frames and more than 4 physical pages. Second what do the functions 25 subfunctions 0 and 1 provide me ?. According to the materials I have, function 25 subfunc 0 gives me the number of entries in the mappable physical addresses array and function 25 subfunction 0 gives me an array of segment addresses and physical page nos. I am not sure how to use the information contained in this array ? I would appreciate if somebody can help me. Thanks vas@attunix.att.com
