This utility allows you to configure the board so it will operate without interference from the other boards in your computer. This chapter describes how to run the Configuration Utility using the installation diskette included in the product kit. Before you begin, make a copy of the diskette as a backup. NOTE It is possible to install the board before you run the Configuration Utility, but you receive a system error on the terminal screen when you boot your system. (See Chapter 2 for the installation procedure, if you wish to install the board first.) 1-1 1-2 Configuration 1.2 The Configuration Utility The EISA board settings (called default settings) are already configured to correspond to the needs of most users. If they do not meet your needs, you must use the on-line Configuration Utility to change them. Figure 1-1 shows an overview of the system configuration. 1.2.1 Accessing the Utility To access the Configuration Utility, use this next procedure. 1. Load the diskette that contains the EISA system configuration (!DEC4220.CFG) software, and copy the .CFG file to the directory that contains all the configuration files in the system. 2. Set the system to the drive being used. 3. Type SD at the prompt. This command displays the Set Up menu. 4. Select the Basic Configuration option from the Setup menu using either MB1 or the keyboard arrow keys. 5. Select the slot, using either MB1 or the keyboard arrow keys, where you plan to place the board. The configuration menu for your board should now appear. 6. Choose to either keep the default settings, or to change them, as described in Section 1.4. 7. Exit the Configuration Utility by typing ------------------------------------------------------------ ------------------------------------------------------------ Alt ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ S ------------------------------------------------------------ ------------------------------------------------------------ . If you select Save at the prompt, you save the settings you have changed. They remain the same unless you re-enter the Configuration Utility and change them. Configuration 1-3 Figure 1-1 System Configuration Overview 1.3 Menu Choices Using the Configuration Menu, you can choose to set the EISA board to specific settings for: · Network interface · Network interrupt · I/O memory address · Network controller buffer · Remote boot · Remote boot time-out If you do not know the settings for the other boards check with your system administrator for a list of the settings. If you configure the board to the correct setting, and a conflict occurs, you need to change the setting on the board. This is described in Section 1.4. NOTE If the board is set to use a setting that another installed board uses, your computer or other boards may not operate correctly when you boot the system. 1-4 Configuration 1.4 Changing Settings This section describes how to change the settings on the EISA board using the Configuration Menu. 1.4.1 Network Interface If the network interface selection is changed, then the Network Select jumper on J1 must be changed manually. Figure 1-2 Network Interface 1.4.2 Network Interrupt You use the Configuration Utility to select an interrupt request line (IRQ). The board uses one IRQ line for the network interface (NI). By default, this is set to IRQ5. IRQ9, IRQ10, and IRQ11 are also available. The Configuration Utility displays an error if you try to set the IRQ to that of an existing board. Figure 1-3 Network Interrupt Configuration 1-5 1.4.3 Network Controller Buffer You use the Configuration Utility to set the memory buffer address range and size. There are two selectable buffer modes. · 64 KB · 32 KB By default, the memory address range is set to 64-KB mode (Figure 1-4). Figure 1-4 Network Controller Memory Size Assignment Only one board can be set to use a given memory address range. Check the documentation supplied with your personal computer and other boards to determine memory address requirements. If other boards in your computer use memory ranges that conflict with one of these ranges, select a range that is not used. 1-6 Configuration 1.4.4 Remote Boot This menu choice determines whether the remote boot feature is enabled or disabled. By default, remote boot is disabled. Figure 1-5 Remote Boot Enable/Disable 1.4.5 Remote Boot Time-out This menu selection controls the time-out period for trying to enable a remote boot operation. By default, this is set to 30 seconds. Figure 1-6 Remote Boot Time-Out Configuration 1-7 1.5 Default Settings The EISA board software is preconfigured to work in most installations.
