Guru Meditating in style

[Michael Sykes]

If thats possible is there also a tool to change the 'Software failure' into a 'Guru meditation' message out there?

The guru code vector (RT_INIT) can be found in the alert.hook module (kickstart). Search for the string 'alert.hook' in the ROM (file) and add like #$23 to that offset, the RT_INIT (guru) code execution address should be stored somewhere there (depending on kick version).

        ; The "alert.hook" mechanism
        ; --------------------------

        ; This is a RomTag.  At system startup, this will be found and added
        ; to the resident module list.  Since it has the RTW_COLDSTART flag
        ; set, it will be initialized along with the other libraries,
        ; devices, etc.  The RTF_AUTOINIT flag is not set, therefore, the
        ; code at RT_INIT is called.

        ; The code at RT_INIT is the Guru routine.  This reads the LastAlert
        ; field in ExecBase.  If this is not -1, then an alert is still
        ; outstanding (from before the reboot), and this puts it up, lets
        ; the user click the mouse button, then returns.  The resident
        ; module initialization then continues, the DOS boots, and the
        ; system comes up.

        ; The purpose of all this is to allow the system to defer display
        ; of a guru message until after the system has been cold-started.

This is from kick 1.2, but I checked, and the alert.hook module is available in 3.1 also.

EDIT:

Perhaps not needed, but uploaded GOMF v3.0 to the zone. Thanks goes to idrougge @ AUGS.
