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

   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
