All true, so far.

Not so.  You can use ResEdit to construct the new icon (actually an
ICN# resource), close it, then option-open it to get the hex data.  Go
to the resource with the old icon, cut out that data, and paste in the
data for your new icon.  ResEdit's actually very good for this.

That's backwards.  It's immediately *before* the "Where:" string, not
after it.

In the Jasmine driver, it's much easier, because I got tired of
Jasmine bugging me about icon changes.  To find the icon in your
Jasmine formatter, open the SDRV (SCSI Driver) resource, and search
for the string 'ICON'.  From there to the "Where:" string is the icon
data.  I suppose I should have put it in a resource and patched the
driver at installation time, but that's all hindsight now.

So true.

I would!
