Yeah, the programmer didn't know very much of anything when he wrote the 
program and never could figure out how to use the Gestalt crap in MacOS.  
(Hopefully I didn't offend anyone with my comment since I wrote it.)

The ROM Sniffer utility isn't really used much any more.  It was 
originally designed to try to find the ROM addresses for the internal 
tables used by the MRG code in the kernel.  NetBSD/mac68k doesn't use 
this approach in GENERIC kernels any longer and instead uses a direct 
hardware approach to dealing with the ADB and such.  The MRG approach was 
to attempt to use the Apple routines that were in ROM on the system.  
This approach has some problems that weren't easily solved.  Many of the 
"newer" 68k Macs use System INITs to patch the ROM code and those patches 
aren't available to NetBSD.  In some cases we couldn't determine which 
set of ROM routines to use for certain models of Mac, probably because of 
the MacOS patches.

So unless you're looking at building a custom kernel that uses the MRG 
code the output of the ROM Sniffer is pretty much useless.  The only 
other use of the routine would be to try to find other ROM values that 
might be used in extending support to cards and devices on the Mac that 
we currently don't support.  I think Hauke made some mods to the ROM 
Sniffer to try and locate some of the info for the floppy when he was 
working on the floppy code for NetBSD. Since then I don't think anyone 
has found a real use for the ROM Sniffer.

Hope this helps,
