In porting our MS-DOS-software to XENIX-Systems we will have to write a device driver based on memory mapped I/O. The device controller expects 32K contiguous memory mapped to physical adresses within the first MB. Do XENIX-Systems offer facilities to prevent a memory area from being allocated, swapped or moved. Any information would be appreciated. Thomas Gaenshirt MODICON Europe
