Lisa Error 45

Was trying to get some code running on my Lisa and got this:



Anyone know what it means?  Is there a document with a list of these somewhere?  I googled a bit but obviously missed the keyword.

Here's a link to the table of startup error codes: https://lisafaq.sunder.net/single.html#lisafaq-hw-rom_error_codes

Looks like a Bus error (not entirely sure what that entails, but maybe a poke around the Lisa boot ROM source would get you somewhere?)

Bus error means you tried to access memory that does not exist or belong to you or the MMU hasn't mapped. It's equivalent to the unix segfault.

You can tell it was late at night, can't you.  I really have no excuse for not looking at the FAQ...

Bus error means you tried to access memory that does not exist

That would make sense.  There's a pointer in this code where I'm not sure where it ought to be initialised (I don't think anyone has tried to get this building for a very long time, partly because there seems to be a critical file missing from the source tree and nobody's noticed, so a little reconstruction is being required)
