Title: Installing Locator on a PC Workstation

If a PC is running Locator Service, it should be dedicated to this task
only, as using this machine as a workstation may have adverse effects on
NetBIOS applications.

When installing Locator Service on a PC workstation, there are three
parameters that can be tuned at the command line:

   *  Number of names (represented as -n)
   *  Number of nodes (represented as -a)
   *  Number of receive buffers (represented as -b)

The Names parameter (range 1-23200) specifies how many unique NetBIOS
names can be in the Locator.  Up to 16 unique names can be used on each
workstation.  The number of names required depends on the NetBIOS application
being used.  Each name requires 38 bytes of memory.

The Nodes parameter (range 1-1500) specifies how many full NetBIOS
workstations (nodes) can be tracked by the Locator at one time.  Each node
requires 44 bytes of memory.

The Buffers parameter (range 1-40) specifies how many Locator receive
buffers are available.  Generally, increasing the number of receive buffers
improves Locator performance.  Each buffer requires 240 bytes of memory.

To run Locator on workstations with either full or partial NetBIOS, add
a LOCATOR.EXE statement to the AUTOEXEC.BAT file between the RUNMINDS
and SETNAME statements:

   RUNMINDS mindspro mindsbuf...
   Login
   Locator.exe -n200 -a40 -b2
   .
   .
   NetBIOS
   SETNAME $$3Com$$

Locator must have the local Name server's network number.  Without it,
Locator defaults to network number 0, making NetBIOS internetworking
impossible.  Either the LOGIN command (shown above) or the GETNET command
can be used to get the local Name server's network number.  GETNET is
preferred for PCs dedicated to running Locator.

On workstations running LPO and Locator, GETNET must be used if NetBIOS
internetworking is desired, because LOGIN cannot be run before loading LDR
in the AUTOEXEC.BAT file.  Append the statements Program=GETNET and
Program=Locator.exe (with parameters) to the end of the LDR.CFG file.
