configuration must be saved to
NVM and the system rebooted before the E/ISA boards can be used.
Drivers and Device Files
Running
eisa_config is not the only task necessary when adding an
E/ISA board to a system.
Corresponding
I/O drivers must be added to the kernel and appropriate device files must be created. These
steps are the same as is required for any
I/O card, and can be performed either before or after running
eisa_config . The important thing to remember is that the
E/ISA board cannot be used until all neces-
sary tasks are complete.
Interactive Commands
If the command form
eisa_config is used, eisa_config
runs in interactive mode. Interactive
mode conducts configuration changes by using a series of keyboard commands.
eisa_config prompts
for a command, executes it, displays the results of executing the command, then prompts for the next com-
mand. Interactive commands are broadly grouped into five categories:
action Alter the configuration in some way.
display Show current configuration.
cfg Manage
CFG files.
comments Display help and comments information found in CFG files.
help Help for using eisa_config interactive commands
The action commands are:
add cfgfile slotnum Adds a board to the current configuration. cfgfile specifies which
CFG file
corresponds to the board and slotnum identifies the slot where the board resides.
remove slotnum Remove a board from the current configuration. slotnum identifies the slot
where the board currently resides.
move curslotnum newslotnum
Move a board that is currently configured in one slot to a different slot. curslot-
num and newslotnum specify the current and new slot numbers, respectively.
change slotnum functionnum choicenum
Change the choice used for a given function. All three arguments, slotnum,
functionnum, and choicenum are required. The function number (functionnum)
and choice number (choicenum) can be obtained by using the show board
command on the slot in question. Function numbers are of the format
Fnum and
choice numbers are of the format
CHnum. Note that a board must already be
part of the configuration before the change command can be used.
When eisa_config adds a board, it selects a choice for each function. Gen-
erally, the first choice for each function is selected (the default). However, in
order to resolve conflicts, eisa_config may select a different choice for a
given function. When specifying a choice for a particular function by use of the
change command, eisa_config always uses that choice; it does not select
a different one, even when a conflict needs to be resolved.
save [ filename ] Save the current configuration. If the current configuration is not conflict-free, a
warning is produced and the save is not done. If you specify a file name, the
save is done to that file; otherwise, the save is done to NVM (and the
/etc/eisa/system.sci file). Note that the quit command also (option-
ally) saves the configuration to NVM (and file /etc/eisa/system.sci).
When the configuration is saved to
NVM, a log file is created that provides a brief
desription of the new configuration. The log file is named
/etc/eisa/config.log, and contains information generated by a show
command, followed by a show board command, followed by a show
switch
command.
init [ filename ] Initialize the configuration. The initial configuration is retrieved from a file if
one has been specified. Otherwise, it is retrieved from NVM. Note that an impli-
cit init is done when eisa_config is first started. This command should
only be used when the current configuration eisa_config is dealing with is
incorrect. For example, if you make some changes that you decide you do not
