I'm sure it's possible. You'd want some sort of custom electronics between the serial port and the speaker pins. You could shoot for just a resistor type setup that would make sure the proper voltage is supplied, but you'd be better off setting up a relay that would get tripped by the voltage sent to the speaker, then supply the proper voltage via a battery to the selected pins on the serial port. Hacking the serial port driver wouldn't be that hard. There is plenty of example code out there. There is probably something else in place. I'd bug Mike Smith first. He does the raid stuff for the core group. I think his email address is msmith@freebsd.org. Good luck. :) On Tue, 09 October 2001, Paul Chvostek wrote: > > > Thanks for the advice, but.... > > If there is a speaker on the Dell PERC card, I suspect I wouldn't be > able to hear it from where I'm sitting.

Most of the cards have their own built in speaker that will signal you with a beep system.

I can say that from experience the beeping is really frelling annoying. A lot of OEM's elect to turn the speaker off in the config. You should ctrl+m during boot and turn it back on. My megaraid 1300 has been awesome so far. The only issue is that for some reason I couldn't get into the config from the boot prompt. I had to download a disk image of a win98 boot disk, and spend a saturday afternoon finding MEGACONF.exe for DOS.
