ETHFLOP - a network-backed floppy emulator for DOS
Copyright (C) 2019-2024 Mateusz Viste
ETHFLOP is a DOS TSR that emulates a floppy disk drive using a floppy image over Ethernet. The emulated (virtual) floppy disk is stored on a server as a floppy image. All the communication between ETHFLOP (the TSR) and its server (ethflopd) is performed 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 or SLIP) and a suitable packet driver. The server and the DOS PC must be connected to a common Ethernet segment (same LAN). The server can run either Linux or DOS.
Shortly said, ETHFLOP:
- emulates many types of virt. floppies, from 360K up to 31M
- needs only a packet driver for connectivity
- presents a block device to DOS, almost undistinguishable from a real FDD
- fits in 2K of memory (can be loaded high)
