DIS_PKT is an NDIS transport driver for DOS that provides a Packet Driver (v1.11) interface on top of an NDIS MAC driver. It acts as a shim, allowing Packet Driver applications (TCP/IP stacks, etc.) to share an Ethernet or Token Ring adapter with NDIS clients.

Originally written at FTP Software (1988-1991), with major contributions by Joe R. Doupnik (Utah State University) and Dan Lanciani. The last official release was version 1.11 (December 1992).

This fork picks up where 1.11 left off, with fixes for use on period-correct DOS hardware and emulators (DOSBox, 86Box, PCem, etc.):

• Proper section lookup from PROTOCOL.INI via the Protocol Manager, matching the module by its DRIVERNAME keyword rather than relying on a hardcoded section name. This follows the same approach used in pktndis.

Requires TASM, TLINK, and EXE2BIN on the PATH. See src/makefile for details.

cd src
make

An OEMSETUP.INF is included for automated installation through the network setup of Microsoft LAN Manager or Windows for Workgroups 3.11.

See doc/dis_pkt.txt for the original documentation by Joe R. Doupnik, covering configuration, PROTOCOL.INI keywords, and usage.
