You must install the PC LAN Support program so that you will have the proper device drivers. You should use the COPY command to copy the device drivers from the LSP 1.2x diskette in drive A:.
MD C:\LSP COPY A:\DXMA0MOD.SYS C:\LSP COPY A:\DXMC0MOD.SYS C:\LSP
Additionally you should get the RESETOKN.SYS device driver and copy it into the C:\LSP directory.
COPY A:\RESETOKN.SYS C:\LSP

RESETOKN.SYS can be retrieved from:
