#  The following is an installation script for use with System V, Release 3
#  using either linkable or installable device drivers.
#  
#  This script does the following:
#    -- Finds the current major numbers and driver configuration parameters.
#    -- Asks the user if the major numbers need changing.
#    -- If yes, it prompts for new major numbers and modifies the driver
#       config files as appropriate.
#    -- Asks the user if the driver configuration parameters needs changing.
#    -- If the system requires any driver config parameters to be changed, it
#       modifies the space.c and config file.
#    -- Checks for conflicts on the interrupt vector set in the previous
#       steps; if one is found then a bunch of instructions on how to
#       proceed are written to the screen.
#    -- Adds the driver(s) to the kernel configuration files.
#    -- If necessary, changes netd.cf for the driver.
#    -- Removes any existing special files and create the special files
#       (devices) required by HBTCP.
#    -- Calls kconfig to build a kernel if the user wants to.

There is a conflict with the device "$matchdev" on interrupt level
$irqvec.  Please resolve this conflict by changing the Interrupt
Request line of either the conflicting device or the $NAME board.

Change the IRQ value of "$DNAME" in ${SDEVICEDIR}/$DNAME file or make
modifications to the configuration file of each conflicting device
resident in ${SDEVICEDIR} directory named after the corresponding
device.  If you are changing the interrupt vector and request
line of the $NAME board then you will need to do the following:

     1    Abort this installation.
     2    Change the IRQ jumper on the $NAME board to the desired IRQ
	  level to reflect the desired IRQ level.
     3    Restart this installation script by executing sysadm, giving
	  the correct value for the interrupt level when asked by the
	  script.

This conflict must be resolved before the new kernel can be linked.
Please refer to the INTERACTIVE UNIX TCP/IP software and $NAME hardware
installation manual for more detailed instructions on changing the
interrupt vector, I/O address and etc..

Now interrupt this script (usually the DEL key) to abort the
installation...
