- purpose: Patch INITs to bypass ICON display during boot-up.
-
- soapbox: Every INIT which displays an ICON at boot time (especially those
- which are also CDEVs) should allow the user to enable or disable
- the display from the control panel ala Vaccine. (bravo!!)
- I rather like StartupScreens of my own choosing once in a while,
- and nothing ruins it more than a string of ICONS marching across
- the bottom. For debugging purposes, however, it is very useful to
- have the ICONs visible to trace the boot progress.
- Hope all you future INIT/CDEV programmers are taking notes.
-
- solution: Patch a copy of the original INIT file with FEDITplus or other file
- sector editor. By replacing the ICON display subroutine branch
- instruction with a NOP (no operation) instruction, we can bypass
- the hard-coded ICON display at boot time, leaving the ICN resource
- intact. The following patches have been successfully tested:
