This README file accompanies JUMPERS v2.01.
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 <Esc>.
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 <Esc> and then <Enter>.
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.
