- I've got a DTK 486-33, with DTK's own BIOS, and a Symphony chipset. One of
- the config options is a choice between relocating 0K and 256K of the shadow
- ram. The manual is quite vague about what this does, but with 0K relocated,
- I have 384K of memory dedicated to shadow ram, and with 256K relocated, only
- 128K of memory is used that way.
-
- The trouble is, the 256K relocation seems to confuse QEMM386 2.42. I get
- weird crashes as though it thinks my memory is quite different than it
- really is. If I ask for 0K relocation, the problems go away - but so does
- 256K of memory.
-
- Does anyone know exactly what this relocation does, and how to tell QEMM to
- live with it?
