This would work. But, if we are to "cook up" a new scheme to handle memory beyond 4-GB, why limit it only for RAMdisk usage? If the XMS drivers/handlers support such "large" memory, EVERYBODY could use it! >> But, a much-LARGER "issue" here is "Do we really NEED all this?"! > > 6, 12 or 24GB RAM machines are becoming more common now with the Intel > Core i7 platform (uses triple-channel memory, so 3 or 6 banks filled > DIMMS, 2 or 4GB per DIMM). Soon, we will need something like the Enterprise with a guy named "Data" to hold and run such MONSTERS! I must be in a minority: I still think an efficient computer CAN be achieved with only 4-GB! > My use would mainly be > 1) use up all RAM in my system in a useful way. > 2) use RAM as temporary storage for all harddisk-affecting activities, > mainly creating drive/disk/partition images, and write them to CD (up to > 700MB) / DVD (4.7 or 8.5GB ) /Blu-ray (up to 50GB at the moment). Can you not read up to 2-GB of new data, while simultaneously writing out the PREVIOUS 2-GB of data?? I assume hard-disks are still a LOT faster than writing to CD/DVD drives, so a simultaneous I-O program should work! Or, are "simultaneous I-O" schemes no-longer taught at computer schools??

Most remaining DOS users/programmers, including me, have little time for "fun and games" in today's CRASHING world economy! I would be "up for the challenge" of working with Japheth and implementing some sort of over-4GB XMS scheme which benefits ALL users of DOS systems, IF as I noted before such a scheme is REALLY necessary. But a "fun and games" task, for only 1 highly-specific application like copying a DVD/BluRay disk, is NOT the best use of my time! ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
