Lines: 15 Is there anybody who can tell me how to use the unused memory in the D- and E-segment. This piece of memory is still not used and now I would like to use it. Originally it is reserved for ROM cartridges and stuff like that, but the Expanded Memory Manager does use 64K of it. My computer, a Laser XT3, contains an EMS-board, which I don't use, so it should be possible to use it, because EMM.SYS does so. HOW?? When I try to put some data into the D-segment with for instance Debug, it isn't there when I look at the same memory location after that. AFD displays the following message:' Patch location not in RAM.' How do I let the computer know it is RAM instead off ROM? John Graat.
