[comp.sys.ibm.pc] memory use

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?
