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.

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.
