DAutomatic bootup - For automatic bootup at power on, the select code of the LAN card on the client machine must be set to 24 and the CPU switches on the remote computer must be set for autoboot. Refer to the installation and service manual for your computer for CPU switch information.
Upon power"up, the client sends out a broadcast message to the LAN to be booted up. However, you could also configure a particular or a multicast download server station address onto the client's LAN card. The client would then be serviced by a particular server or group of servers on the LAN. This configuration can be set by running the LAN Node Manager program, NM, when the client's card is in the backplane of a disk"based system. See Chapter 5 for more information on using the Node Manager software.
DRequired server software - The following modules are documented in this chapter:
IPL_BUILD and IPL_EDIT create the configuration file containing each client's LAN station address and memory"based system download file. IPL_BUILD creates the configuration file, and IPL_EDIT is used to alter it.
DISPATCH monitors the LAN packets and determines whether the packet is to be handled by the remote VCP monitor or the LAN Node Manager.
VCPMT and RMVCP download the operating system to the memory"based node and handle the remote VCP session. VCPMT is the monitor and RMVCP is the user interface to
VCPMT.IPL_BUILD and IPL_EDIT - Configuration Files
A configuration file is needed to specify the memory"based system download file name and its client. More than one system and/or client can be specified. You create the configuration file with IPL_BUILD and modify it using IPL_EDIT. The names of these programs were derived from the term, IPL, Initial Program Load.
The default configuration file is /FILES802/IPL_TABLE.TXT.You can also use EDIT/1000 to modify the configuration file once it has been created using IPL_BUILD. The configuration file is a type 4 file. Make sure that you do not accidentally truncate the records as you edit. Otherwise, the entry in the configuration file becomes corrupt.
The configuration file is used by the VCPMT monitor and RMVCP, the remote VCP program, to determine which system to download and its destination.
IPL_BUILD and IPL_EDIT prompt you for the following entries. Enter the required information in between the square brackets ([]), left justified.
| IPL table file name | The name of the configuration file. The default file is |
| /FILES802/IPL_TABLE.TXT. A different file can be used for |
| another server system, but VCPMT always looks for |
| /FILES802/IPL_TABLE.TXT. |
| Node name | The name of the client node. Up to 17 characters can be specified. |
