Can anybody tell me the key combo for re-set the Firmware on my e-Mac?Thanks, Buck

I'm not sure what you want, or think you want to do.
Firmware is data that is stored in an EPROM chip, and it's something you might upgrade, but not reset...
Are you thinking of zapping the PRAM? That is Command-Option-P-R held immediately after the startup chime, until the chime has sounded five times in all.

reset-nvram <enter>
another "OK"
reset-all
and the thing should reboot! If you're having problems getting it to boot off a particular drive (should you have more than one volume) you can reboot while holding down the option key by itself and you will be given a choice of bootable volumes that the open firmware finds!

To get into the Open Firmware on that machine you hold down Command-Option-O-F (for open firmware) when it's booting up and you should go into a sort of text mode which ends in a prompt with "OK." When you get that you should type the following:
reset-nvram <enter>
another "OK"
reset-all
and the thing should reboot! If you're having problems getting it to boot off a particular drive (should you have more than one volume) you can reboot while holding down the option key by itself and you will be given a choice of bootable volumes that the open firmware finds!
reset-nvram <enter>

I wasn't sure of the key strokes. You conffermed that I was doing it correctly.
So here's. the problem.
When resetting the firmware. I get a (word unknown) when I type (reset-nvram).
Ever hear of this happening? Thanks, Buck

I can try it on an eMAC tomorrow if you would like me to do so. I would say that Open Firmware could be messed up and you could "update" the firmware if it is messed up! It could also be that you didn't type it correctly (it should be "reset-nvram" with no spaces between)!
I do have it typed correctly.
I have had to reset my firmware in the past.
Things went fine then. Buck

Try resetting the computer by typing "reset-all" at the Open Firmware prompt. If this does not seem to make a difference, the fault maybe hardware related. Typically, a defective processor card causes these types of symptoms.
I just read something on the Apple Service Source website about someone who had been experimenting with a Linux on their computer and got a similar message in the Open Firmware to what you're getting. They mentioned "resetting the PRAM" as a possible cure: Command-Option-P-R.

How many times have I said that only to discovered ( or worse, have it pointed out! ) that I actually only thought I had typed it correctly. 
Since you are basically in the Terminal, you have to be absolutely, positively, 100% correct. You will never win an argument with the Terminal by claiming you have done something correctly and "it" is broken. 
As a tip for showing input in Terminal ( and just about any other program ), I'd suggest setting the font to one that shows lower case "L" differently than the number "1". It is also great to have one that makes the letter "O" and the number "0" easily recognizable. Of the choices available here, I tend to use Courier ( because I can remember and spell it in FastReply!
).Thus, the suggested commands to enter when in Open Firmware are:
reset-nvram <enter>
[response on screen] "OK"
reset-all

Buck - For what it's worth I just went into Open Firmware on an eMAC and everything worked just like it did on a Powermac or iMAC or whatever else I've ever worked with. It also looks like there are no updated Open Firmware for eMAC's on the website. The reset is actually the "reset-all" command so maybe it doesn't matter. Why are you trying to do the reset; what problem are you trying to solve?
I just read something on the Apple Service Source website about someone who had been experimenting with a Linux on their computer and got a similar message in the Open Firmware to what you're getting. They mentioned "resetting the PRAM" as a possible cure: Command-Option-P-R.

Thanks for the help. I no longer had a problem.
Problem solved. I hope.
Ya'll have great day. Buck

And it worked. Even though I typed the very same over and again. Go figure.
Goes to show one never knows how a problem will get solved if at all.
Have a great day, Buck

BTW, did you know that there is a "TS" Frappr Map? Unfortunately, it appears that Flash is now required, the map can no longer show as much of the world as previously, the page must be much wider to keep from scrolling horizontally and it is now tightly linked to a bunch of "My..." junque. It's still Beta and free, so what should I expect. I must apologize for not visiting it more, I discovered that at some point 'our' map became visible to the public list of maps, that might explain some of the SPAM the board/members got with TS spoofed addresses. My bad!

But, how does one know when the firmware should be re-set? Or zapping the pram, for that matter. I do these things once in a blue moon, but only because I think I should; I mean, it's never hurt to run the checks.

I'd just reset the PRAM by shuting the machine off and reset it from a cold boot. Press down the Comand-Option-P-R afer you hear the chime is done on boot and hold the down until they chime 5 times as ktxbear says, then let go.
I haven't done it in a long time on OSX.
