I wanted to ask: to what degree does FreeDOS implement the redirector
interface?  Are there any known incompatibilities?

The reason I am asking is that I started a project that I was never able
to find time finish (and don't expect to have any more for the
forseeable future) to write a 9pfs redirector for DOS, which would let
DOS access a filesystem (as opposed to a disk image) using Qemu.

If there is interest, the code so far is at:


It contains a lot of infrastructure work done (tested under MS-DOS 6.22)
but not much of the actual file operations.

This also requires that any protected mode memory manager (EMM386 etc)
implements the DOS VDS (Virtual DMA Service, INT 4Bh AH=81h) API.
