Am I the only one out here that finds the beep that the mac makes on power on to be annoying? I'm doing some program development and everytime I have to reset the machine everyone in the office knows that I've bombed again! IBM PC's don't beep, why should macs. I hope the new ROMs I've been hearing so much about eliminates the beep.

Many of you have seen that there is a RESUME button on System Error dialogs.
With most software, it is dimmed, but developers can set a resume routine that
can be called when a system error is generated. It is set by passing an address
in the InitDialogs ROMcall. This address will be called if the user presses the
RESUME button in the error dialog.
A good call to use is the ExitToShell command. This will return the user to th
finder where he can choose whether to edit again, or whatever. To do this in C,
do the following:
resumeProc();
{ExitToShell();}
and in your main procedure:
InitDialogs (resumeProc);
The resume procedure will usually work, but there are a few cases where it won't
for a reason that I don't know.
Hope this helps...

Yes they do. The ROM start-up diagnostic on the IBM PC uses a beep to
signal whether the CPU test completed successfully, and other beep patterns
to signal if it failed (and for what reason). This is done in case the
display is not working, so you can find out whether it's not working
because the CPU couldn't initialize the display, or whether the display is
bad but the CPU is fine. Actually, the IBM PC also makes a distinctive
"honk-honk" noise from the A: disk drive whenever you reboot it, also,
because they move the heads in and out, with the stepping rate set to a low
(and thus noisy) rate, in order to test them before loading the OS. At
least the mac makes a nice bell tone, instead...

Such a routine was posted on the network a while back in BinHex 76.83 format. I tried it. It didn't work. Maybe it could be blamed on the fact that I was using BinHex 21.54 instead.

I have noticed that newer Apple software (notably Finder 4.1) beeps much less, but the ONE beep that I can NOT get rid of (even with the lovely Control Panel) is the Power On beep. ANNOYING. By the way, responses to this message having to do with the Resume command are NOT solutions. This is about restarting the Mac, not how to add Resume to an application. Darin Adler ihnp4!tmq!darin

Writing a resume procedure is no mean feat. Since exit to finder doesn't rebuild the system heap from scratch your takings some risks in letting the finder attack on your disks at that point. Consider what happens if it rewrites a disk's directory without checking that the directory is absolutly pure and noble, bye bye data... I'd be interested in what other people have done to create a reset procedure that is reasonably safe. For example do you forcably dismount the disks? Do you reinit everybody? Do you check the consistency of some read only data structures and use them as a vote of confidence? My only use of this feature is to get some oportunity to look at things prior to the machine rebooting.

Consider what > happens if it rewrites a disk's directory without checking that the > directory is absolutly pure and noble, bye bye data... I guess I'm not as paranoid ... I just exit to finder. After probably scores (hundreds?) of exits like this I've had absolutely no trouble. On the other hand, I haven't ever needed to do this while mucking with files; maybe I've just been lucky. (Actually, I really exit to SkipFinder; that reminds me, I need to send Darin some money for it...). Thanks for the warning; I'll be careful about not restarting if I've been writing on the disk.
