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. ÿ
