Using the Boot Monitor Setup menus, you can change a subset of terminal configuration parameters. Using Boot Monitor Setup, you can set the following:

• Network addresses required for booting and network communication
  

• Files and directories needed for booting
  

• The order of booting attempts
  

• Monitor resolution and dpi (dots per inch)
  

• Keyboard type
  

The Boot Monitor Setup menus provide a help menu and help text for each item.

The content of the Setup menus differs slightly depending on the Boot Monitor version you are using.

Parameters are saved to NVRAM when you exit the Setup menus unless you specify otherwise in the Done submenu.

Starting Boot Monitor Setup

To start Boot Monitor Setup from within the Boot Monitor (at the > prompt), press the Setup key or type the se command. The Boot Monitor Setup Menu bar and Help window appear.

The menu bar displays the names of the six submenus:

• Help-how to access the windows, move from item to item within the windows, and exit from Boot Monitor Setup
  

• Keyboard- keyboard type
  

• Monitor-monitor resolution, refresh rate, and dpi
  

• Network- IP and NCDnet addresses
  

• Boot-names and location of boot and configuration files and specify file transfer protocol preferences
  

• Done-save changes, reboot the terminal, return to the Boot Monitor, and restore original parameter settings
  

To move from one menu to the next, use the left and right arrow keys. The active menu name is highlighted, and the corresponding window or submenu appears.

Note:

If you are using a keyboard that does not have arrow keys, you can remap the movement functions to other keys. See "Programming Navigation Keys for Boot Monitor Setup Menus".

To move from field to field in a window, use the up and down arrow keys. Below the window, a description of the current field is displayed.

If you enter an out-of-range value in a field, an error message appears. To delete a value in a field, use one of the following methods:

• The Delete key backspaces a character at a time.
  

• Ctrl-U deletes everything you typed in the current field.
  

• The Escape key erases everything that you typed and returns to the previous value.
  

When you select the Keyboard menu, the Keyboard window displays a list of the keyboard types and languages supported by the keyboard group to which the keyboard belongs. The current type is highlighted when you display the window.

To select a keyboard other than the default (usually the US English language type), press the arrow key until you have highlighted the correct type.

Setting Monitor Resolution and Dots Per Inch

When a terminal is first turned on, the display appears at its default resolution (number of pixels in height and width) and refresh rate (in hertz). This setting may not accommodate the highest resolution or refresh rate that your monitor can support. For detailed information about monitor resolution and dpi, see your hardware documentation.

You can use the Monitor menu to select another resolution, refresh rate, or dpi for your monitor.

When you select the Monitor menu item, the two Monitor windows described below appear. Use the right and left arrow keys to move from one window to the other.

The Monitor Resolution Window

The Monitor Resolution window lists the monitor resolutions (in pixels of height and width) and refresh rates (in hertz) that are supported by the video cable attached to your monitor.

To make sure that the resolution or refresh rate you select is supported on the terminal, press Shift-T.

If the resolution or refresh rate that you selected is supported, a grid test pattern appears, labelled with the selected resolution or refresh rate. If the value is not supported, the test grid might not appear.

The Dots Per Inch Window

To change dpi, backspace over the current setting and type the desired dpi.

Setting Network Parameters

Use the Network window to set the basic networking parameters. Table 11-3 lists the fields and how to change them.

Table 11-3 Boot Monitor Setup Network Window

Use the Boot window to set the filenames and directories used in booting. Table 11-4 lists the fields and how to set their values.

Table 11-4 Boot Monitor Setup Boot Window

¹ The Boot File, TFTP Boot Directory, and NFS Boot Directory items must have a combined length of 128 or fewer characters.

² The Config File, UNIX Config Directory, and NCDnet Config Directory items must have a combined length of 166 or fewer characters.

To save parameter settings, restore old settings, reboot the terminal, or return to the Boot Monitor, use the Done menu item, which displays a Done window. The items in the Done window are described in Table 11-5.

Table 11-5 Boot Monitor Setup's Done Window

The Boot Monitor's keymapper allows you to program menu navigation keys for unsupported keyboards that do not have defined arrow keys. You can, however, change the navigation keys for any keyboard.

Please read the following usage notes before you begin:

• As you assign keys, write down the key assigned to each navigation function in case you forget the new assignments after exiting from the keymapper. This is because the keymapper displays only the keycode, not the legend on the key. For supported keyboards, you can check the keycode against the keyboard maps. For unsupported keyboards, however, there may be no way to find out which key corresponds to a given key code.
  

• If you assign a number key to a navigation function, you can no longer use the number key for entering data in the Boot Monitor Setup menus or for entering data with other Boot Monitor commands.
  

• Mapping keys and then attaching a keyboard that has a different layout may cause problems if the assigned keys do not exist on the new keyboard.
  

• Do not assign one of the defaults to another keymapper function. For example, if you assign the default key for the left function to the right function but do not assign another key to the left function, pressing left causes the cursor to move right. There is now no way to move the cursor left. Be especially careful that you do not lose the escape or setup functions.
  

Follow these steps to map the navigation keys:

1. Enter the Boot Monitor and type the following command:
   

   
   > km 
   

   
   The current keymap is displayed:
   

   
   Current keymap:
   Key         Current        Customized
   --------------------------------------
   left        (default)      no
   right       (default)      no
   up          (default)      no
   down        (default)      no
   setup       (default)      no
   escape      (default)      no
   backspace   (default)      no
   Change any items [y/n]?
   

2. To start changing the keymap, type y and follow the directions displayed:
   

   
   Change any items [y/n]? y 
   Press one of the following keys:
   <key>       Key to use for this item (must not be A-Z)
   Return      Do not change this item
   d           Restore default for this item
   q           Quit without any changes
   

   
   When you press a key, its code appears in the New column. In this example, the user has remapped all items but one:
   

   
   Key         Current       New           Customized
   --------------------------------------------------
   left        (default)     0x6B          yes
   right       (default)     0x74          yes
   up          (default)     0x75          yes
   down        (default)                   no
   setup       (default)     0x76          yes
   escape      (default)     0x77          yes
   backspace   (default)     0x7E          yes
   Save new keymap in nvram [y/n]?
   

3. To save the new keymap, type y:
   

   
   Save new keymap in nvram [y/n]? y
