ethflop - a network-backed floppy emulator for DOS
Copyright (C) 2019 Mateusz Viste

ethflop is a DOS TSR that emulates a floppy disk drive. The emulated (virtual) floppy disk is, in fact, stored on a Linux server as a floppy image. All the communication between ethflop (the TSR) and ethflopd (the Linux daemon) is exchanged over raw Ethernet. No need for any network configuration - the DOS PC only needs to have some kind of Ethernet adapter (physical or emulated, for example through PLIP) and a suitable packet driver. The Linux server and the DOS PC must be connected to a common Ethernet segment (same LAN).

Shortly said, ethflop:
 - emulates many types of virt. floppies (from 360K up to 31M)
 - requires only a working packet driver for connectivity
 - presents a block device to DOS, almost undistinguishable from a real FDD
 - fits in 2K of memory (and can be loaded high)
