pretty straight forward.
* Port DosEmu from Linux to SUN SOLARIS
* boot dos, giving it a lot of memory (for the RAMDISK)
* start XMSDSK
* start MS LANMANAGER as server, and make the ramdisk a shared
resource.
maybe I missed one step or too, but that's the general direction ;)

call a device driver - you don't need that (see below)

you don't need blockio.
you should replace the read/writeblock() in blockio.c;
blockio.c is mostly about caching, and there's little
sense in caching a ramdisk.
