Do I _need_ these "symbol tables" to run bootvis?

Well, I got a basic boot profile run to function,
without a folder full of symbols.

But the TRACE_BOOT+DRIVERS_1_1.BIN is 60MB, which to
me implies a *lot* of information was collected. Bootvis
has a zoom function, and the claim is you can zoom in
on things. Now, whether that is to the subroutine
level (like they were running a code profiler)
or something, I don't know. I haven't run it with
symbols yet to find out.

My symchk run only netted 600MB of stuff, and I could
have sworn the first time I ran it, I got 1.5GB of
downloads.

Symbol tables also come in handy for running various
debuggers. So the topic of symbols would come up,
if you were using a code debugger.

Thanks. I'll try that when I need to.

The main place I intend to run it is when helping others try to figure
out why their boot takes so long (my own, though not of the fastest, is
OK - mainly, I tend to boot when I come in from work [which it does
while I'm doing other things] and then leave it running, as it's stable
enough - those I help need to reboot a lot, though, so it matters for
them); the main person I'm thinking of is a blind person, and I won't be
visiting her until September. I'd been hoping to be able to (install
and) run bootvis on its own, and get something useful from just the
picture like you showed. It hadn't even occurred to me that there might
be a zoom function!

Understood. If I'm honest with myself, I suspect I won't be doing
programming/debugging to that sort of depth now: there was a time when I
would have, but it seems too much like hard work
nowadays/at-my-time-of-life. (Especially when there are kind Pauls
around who will do it for me ...)
