Under MS-DOS 6.22 you have 600K free memory, MS Network Client 3.0 in the most basic install will use 250K. Secondly dual NIC's are not supported, even if it was supported you would have memory issues.

If you must have 2 NIC's and TCP/IP then the only solution is Packet Drivers and WATTCP Stack, see:

http://www.smashco.com/wattcp.asp

Though if you want to connect to Windows Networking and *NIX Samba PC's it is more difficult. If you only want to play games over IPX then there are IPX shims for Packet Drivers

thank you for help,but i don't know how can use wattcp stack of using 2 nic tcp/ip on dos without MS Network Client 3.0 ,thx

You ditch M$ NWC 3.0 completely !

Depends on what you wish to achieve is achievable ?

This page has a section called: "small small How To : Connect to a LAN and run TCP/IP under DOS"

Could you able to bring up two NIC in DOS, if so please let me know I was not able to find it up.
