The M6498 iMac is a 2002 model.
Re OS 9, that machine came with a model-specific version of OS 9.2.2; it can not use any other version of OS 9 for booting. This means that it can not use any retail OS 9 Install CD, nor an install of OS 9 from a different model Mac.
Chances are very slim that you would be able to find an original disk set for that machine, but it would not hurt to check places like Ebay.
Re OS X, it can use up to OS X 10.4.11, the last version of Tiger. It can not use Leopard (OS X 10.5) or later.
You can use a retail Tiger install CD to install Tiger on it.
There is no keyboard command which will defeat or bypass the password prompt at startup - if there were, there would be no point in having a password intercept.
In order to get past the password prompt, you would need to use its original disk set for OS X or a later-version retail OS X Install disk set. By booting the machine to that, you would be able to change the password.
Re USB booting, the USB on that machine is USB 1.1. This is far too slow for booting. And, early versions of OS X are not bootable from a USB drive.
You would do better to use a firewire drive if you want to have an external bootable drive.
So i managed to get hold of the retail cd, now i have booted it up while holding "C" and its shows the apple logo.. however, its either slow or is stuck in that boot (though all i need is to reset or reformat cuz i dont have admin)...is there anything else i can do? or leave the iMac on and see what happens? normally it shows a type of an old mac logo with a face on it, however when booted up with the cd it has like a current apple logo... thanks
There is no retail OS 9.2.2 Install CD. All OS 9.2.2 Software Install CDs are specific to the model with which they originally shipped, and are neither designed nor intended to be usable on any other model.
Since Apple has not yet released any version of OS 9 into the public domain as freeware, any torrent site making it available is not a legal source, and no one here will help you in that endeavor.
Folks are reluctant to mention this, but it's documented on the apple web site.
Get the Mac to set up an additional administrative account. You can then change the password on your old account.
Start with your computer power off. Hold down command-s. Power on your computer.
Type in the following:
The first two commands will depend on your release of Mac OS X. Look at what is typed out in the console to determine the exact format.
# Type the follow two instructions to access the startup disk in read/write. Press return after each command.
/sbin/mount -uw /
#List all files. The l is a lower case L.
#The move command acts as a rename command in this format.
mv -i .applesetupdone .applesetupdone.old
Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

You will need to scroll down to see this post. Search for applesetupdone
Once you have a new administrative account, you can change the password of your old administrative account

White label with gold 9?
The only ones I've seen like that are upgrade-only versions, non-bootable.
Hardcore Mac seems to offer one - but if you read the details, it's a retail OS 9.2.1 Install CD with a burned copy of the 9.2.2 updater on a second disk.
I never saw a retail OS 9.2.2 Install CD sold by Apple.
