English Amiga Board - View Single Post - OS3.2 installed using 3.1 roms but failing now that I have 3.2 roms

Got this install done when my amiga 1200 had the 3.1 rom; then I got the 3.2 roms and now when it boot I get an error when it try to execute the line in startup-sequence:

Code:

LoadModule DOWNGRADE

I get an object not found, and indeed if I type in amigados the string as in the startup sequence, it does give me the error because it does not know what DOWNGRADE means.

I assume that the code was added to the startup sequence only because I did the install using 3.1? Looking at the code seems that the first time it check for exec library, if it is not v47 it does the

Code:

loadmodule L:system-startup ROMUPDATE

and then the second time it does a

Code:

version strap version 47

and if that fail it run the DOWNGRADE line.

Not sure what DOWNGRADE and ROMUPDATE are; those do not look like old school commands; also can't find what strap does and why is it checked in that line.

Any help to understand this would be really appreciated; for now I just put back the 3.1 physical roms and the OS boot fine (twice since it need to load the roms in memory); but I would like to understand this code also for the future, if I want to modify the startup sequence. Thanks!
