Title: Fix for Error Using DEC's Pathworks with EtherLink16

A problem exists when using 3Com's EtherLink16 (3C507 and 3C507TP) adapters
in conjunction with DEC's Pathworks for DOS version 4.0.  The workstation
will display:

   pathworks NDIS datalink, v4.00.039
   MS DOS LAN Manager Netbind v1.1 loaded

Then the workstation will attempt to load network kernel version v4.0.07.
The syntax error will be displayed as:

   Network Kernel version V4.0.07
   Copyright(c)Digital Equipment Corporation.1985,1991.All Rights Reserved
   Error: !! No NDIS interrupt Activity.  Maybe NI_IRQ set wrong or cable
             not attached or hardware/DLL broken!!
   ** ERROR ** Unable to start the Network Scheduler


This problem can be resolved by adding a /N parameter at line 80 or 81
within the STARTNET.BAT file.  The line should be modified to look like
this:

   %boot%\decnet\sch /h /n


Also, follow the instructions that DEC provides when using their
installation software.  Modify their PROTOCOL.INI file and CONFIG.SYS
files, using the following configuration.

;PROTOCOL.INI file created by DECNET.OMO V4.0.17
;                          via DECNET.WIK V4.0.26

[PROTOCOL MANAGER]
DRIVERNAME  = PROTMAN$

[ETHERLINK16]
DRIVERNAME  = ELNK16$

[IPX4MAC]
DRIVERNAME  = IPX$MAC
BINDINGS    = ETHERLINK16

[DATALINK]
DRIVERNAME  = DLL$MAC
BINDINGS    = ETHERLINK16
LG_BUFFERS  = 16
SM_BUFFERS  = 6
OUTSTANDING = 32
HEURISTICS  = 0
;specify IRQ level used by workstation network adapter
;NI_IRQ     = 5


Here is a sample of DEC's Pathworks 4.0 CONFIG.SYS file:

;CONFIG.SYS
buffers=25
files=30
device=c:\decnet\protman.sys /I:C:\DECNET
device=c:\decnet\ELNK16.DOS
lastdrive=z
