the hardware_ram option works but is really limited, as it only works for addresses between 0xc8000 and 0xf0000. the example hardware_ram in dosemu.conf gives you the following mapping: 000c8000-000c9000 rw-s 000c8000 03:06 273019 /dev/mem 000c9000-000cc000 rwxp 000c9000 00:00 0 000cc000-000d0000 rw-s 000cc000 03:06 273019 /dev/mem > > Where can I found documentation about > > the DOSEMU DPMI API for memory allocation, physical > > address mapping, etc? > Nowhere.

True. And in Tim's case it would just be a layer so he can avoid porting.
