This README file accompanies JUMPERS v2.01. The following files are included
for this revision:

JUMPERS EXE 76377 06-26-90 9:30a
JUMPERS HLP 4547 06-05-90 3:01p

This version of JUMPERS corrects problems in v2.00 that result in garbage
characters on the screen and messages saying there are no available options
for NET$OS.EXE or IPX.COM files. Problems in reconfiguring multiple drivers
was also addressed.

JUMPERS is used to

o Reconfigure the IPX LAN driver to match settings you want
to make on a network board in a dedicated IPX
workstation.

o Reconfigure the LAN driver in the bridge (router)
software to match settings you want to make on a network
board installed in a bridge (router).

Note: Only drivers specified as JUMPERS configurable can be
reconfigured. See your Novell authorized reseller for information
about JUMPERS-configurable drivers.

When you use JUMPERS to reconfigure LAN drivers, you do not need to
regenerate the IPX files or bridge (router) software. JUMPERS also allows
you to use custom options not provided in utilities used to generate IPX or
bridge software.

Note: Be sure to reconfigure the LAN drivers before you change the
network board settings.

If "Packet Size" is included in the list of options for the LAN driver you
select in JUMPERS, you can change the workstation packet size specified in
the IPX file of a dedicated IPX workstation. (Although you can change the
packet size specified in the bridge (router) software, the bridge only routes
the packets and there is no particular advantage in making such a change.)

The server packet size specified in the server operating system determines
the maximum packet size on the network (the maximum packet size determines
the buffer size). However, if the packet size specified in the workstation's
IPX file is smaller than that in the operating system, the workstation
operates with the smaller packet size.

Larger packet sizes in the workstation IPX driver will improve driver
throughput, while smaller packet sizes will free up more memory for
applications.

If your driver allows you to use JUMPERS to change driver configurations, we
suggest you set the workstation packet size to the same size as the server's
maximum packet size.

You can make a working copy of JUMPERS on a floppy diskette and use it in the
floppy drive of the console, bridge (router) console, or at appropriate
workstations.

If you load JUMPERS in SYS:PUBLIC, regular users can use it to reconfigure
the LAN drivers in their workstation IPX files.

To reconfigure the LAN driver in the bridge (router) software:

1) Run JUMPERS, specifying the filename of the bridge software when
prompted for a filename.

2) Select the appropriate LAN driver and change options.

A list of options for the LAN driver you select appears with the
current configuration for that driver (If the driver allows, packet
size is one of the parameters).

Select any parameter and choose from a list of supported values.
JUMPERS reads all LAN drivers, including disk drivers and LAN drivers
JUMPERS cannot configure. If another driver in the operating system
uses a particular option, that option will appear with an asterisk
(*).

If JUMPERS cannot configure a driver, the driver will not appear on
the list, but its current configuration will still be used to check
for option conflicts.

3) Exit JUMPERS by pressing .

4) Bring the bridge (router) down.

If you changed only the packet size: All you need to do is reboot.

If you have a bridge with micro channel architecture: Run REFERENCE
(or similarly-named program) to change the board settings. Then
bring the server up.

If you have an AT-compatible server: Turn off the computer. Change
the network board settings. Then bring the server up.

To reconfigure the LAN driver in the workstation IPX file:

Note: Some microchannel workstation drivers are self-configuring.
In this case, use the REFERENCE (or similarly-named) program to
change network board settings. Use JUMPERS only if you want to
change packet size.

1) Log in at the workstation.

2) Run JUMPERS, specifying the IPX file when prompted. For example
(depending on the location of the boot files), type

A:IPX.COM
or
C:\IPX.COM

If you have renamed the IPX file, use the new filename.

3) From the list of "Shell Driver Options," select the options you want
to change and change them.

4) To save the changes, press and then .

5) Exit JUMPERS by selecting "Yes" at the confirmation box.

Note: If you have more than one workstation with the same
configuration, copy the modified IPX.COM file (depending on whether
your workstations boot from diskettes or hard disks) to

o Boot diskettes;

o A network directory (you can download the file to each
workstation's boot diskette or hard disk).

6) Log out.

If you changed only the packet size: All you need to do is reboot.

If you have an AT-compatible workstation: Turn off the workstation.

Change the network board settings. Boot the workstation.
