This functionality is not implemented in dosemu. The relevant API is missing in a DPMI server, the $_hardware_ram option doesn't work, the DMA controller (at least the legacy one of ISA) is not accesible under dosemu and will most likely require a kernel module to be. > Where can I found documentation about > the DOSEMU DPMI API for memory allocation, physical > address mapping, etc? Nowhere. Nobody is working on that. So unless someone needs this badly enough to start coding it up, it will not be implemented. I don't even remember if someone ever asked about this here during the last 4 years. In general this is needed if your hardware is not supported natively under Linux, so it is not a common thing. __________________________________ Do you Yahoo!? New Yahoo!
