I have an iMac 266Mhz 256RAM 40gig HD front loading tray which came with OS 8.6.
I decided to upgrade to OS X, it loaded OK, and ran OK.
However after awhile i got the open firmware when i turned on. Ityped BOOT ( i just guessed that after typing just about everything)and it worked.
I checked the NVRAM settings  ( on foot of some advice)and the Boot Setting is set at 0BOOT. I changed this to MAC BOOT, however when i reboot this changes to 0 BOOT again, i checked the CMOS battery, and this is OK.
This is where im at, still have have to type BOOT.
Any advice would be great

You CAN run OS X on that maching but i absolutely wouldnt recommend it for a variety of reasons. I would check to make sure your firmware is up to date, and run Norton Disk Doctor or Drive 10 (the latest versions). Also do a Permissions Repair via the Disk Utility. You could also boot with command-s held down, then type fsck -y. Do that until it doesnt report any errors.

Sounds like you need to type "setenv auto-boot? true" while still in OpenFirmware. If that doesn't work, you can also try typing "set-defaults" to reset all OpenFirmware variables.

If it still won't auto boot, did you say you had reset the PRAM? If not, check this link out:


As a last resort, you could try opening up 'Startup Disk' in your System Prefs, and select your disk/folder. You should get a dialog verifying your choice, when closing/quitting Sys Prefs.

Good luck.

Thanks for the advice,weed and Cocoa, just in the door so i will give it a go , however weed you say i should'nt run OSX on the iMac, Why? The graphics will be a bit shy of the full load it only has 6MB and i understand that's it, but i don't intend to do much( if any ) graphics work, i dont expect to get the full advantage of OSX, but expect that it should run OK, am i wrong in that expectation? Hope not i think OS X is pretty nifty, and thats before i mess around with its innards!
Thanks for the advice, will let you know how i get on

First 266mhz is going to be painfully slow. I used to run it on a 400 and it was barely usable. The graphics card isnt only going to be slow, its TOTALLY unsupported. You're getting NO graphics acceleration.
